All the power connectors have built in switches (mains, 12v barrel jack) so that when a power source is connected it disconnects from the battery. Often the internal switches in the sockets go bad. The CH Radio/TV switch is a charge switch for rechargeable batteries. When in CH position it isolates the power to the Radio/TV.
In 1971 I was stationed in Vietnam with the 45th Engineers, my wife was home and very pregnant, so in order to get home to be with her at the time of our son's birth , I took a short re-up for 12 months and extended my tour for 2 months so I could get the bonus and take a re-up leave. On my way, our plane stopped at Yakota Air Base and while there I went to their PX for a bit of shopping and purchased a CROWN Television/AM-FM Radio. It was much more compact but did run on AC/DC taking a bunch of C cells or plugging into a car 12 volt system, or had an AC adapter that replaced the battery pack. It was much more compact then yours but she served me well on my last 7 months in Vietnam. When I got home and plugged it into the 110 volt power it blew a resistor. I took it to the on base repair center at Fort Bliss but they could not repair it as the model was never sold in the US and there were no schematics on it. So I took it home and found the bad resistor, or what was left of it, no bands left as she blew, and I just wrapped a bit of wire around the two leads and the little set ran just fine for the next few years. I finally sold it to a fellow who worked part time as a security guard driving his car around some warehouses, he mounted the set under the dash of his 65 Chevy and used it to watch TV on the job. She was still working last I talked to him in 74 when I transfered up to DC to be a ceremonial soldier with The Old Guard.
The satisfaction of bringing a piece of equipment back to life is so rewarding ... I spent 25 years as a field service engineer repairing all sorts of office equipment around the U.K. so I know the feeling of getting any type of object back to life. You follow a sound path in fault finding thats for sure as many people jump here there and never follow a tried and tested format as you do ... also you have patients which is a must ... really enjoyed this video ... congratulations on the repair.
This is legendary! The repair apart this ought to go into the Guinness Book of World Record. Playing the PS5 on a 1978 portable TV. Much respect 🙏 This an engineer retro lover's dream
I used to own a lot of arcade machines, and I always HATED working on the CRTs (which was a pain really because most of the machines needed re-capping!) - still it was very satisfying when I fixed them!
That compartment was to store the mono earpiece so you could watch/listen in private, Great video, I miss old tech that actually worked when you wanted it to !
Hi Vince. Coincidentaly. I bought one of these last year on ebay, exact same colour and model. It also had the exact same issue, no power on. So while watching this video I got mine out (it was already opened up) and I cleaned the same switch you did, and now it works. What are the chances eh? lol
Great job! On radios and TVs with string tuning mechanisms, although the drive knob will slip at either end of the travel, the important bit is getting the displayed frequency to match what the tuner is set to. For radios you can set them by tweaking the pointer mechanism when you are tuned to a known frequency station -ie slip it along whilst not allowing the tuning capacitor wheel to move . You'd have to do the same for the TV in the days the signals were still being sent out.
if you had the hardware to broadcast the signal, and kept the power low enough to avoid getting the attention of any authorities that wouldn't be happy with you for doing so, you could still, even today, ensure that it's tuned correctly by controlling the broadcasting signal. It'd be a lot, and i really do mean a lot, of work for no particular reason though.
Had a similar one to this in the 80's. I used to watch Dangermouse on it in my Dad's office after school, lol. Nice video Vince - really enjoyed the process on this one.

@@Mymatevince You are welcome good sir. I have some of retro/vintage music equipment(Some in a need of repair) and love the aesthetics the builds and design. Keep doing your thing, it is wonderful to see you bring life into old stuff. Respect, peace and love!!
My sister had one of these, I think its brand was Panasonic. Black and white video. The picture was crazy grainy. Still, camping it kept us from running off in the woods for a few minutes. Until the 10 C cells or so died! When the batteries started to die I remember it would loose v sync, you could still get another couple minutes out of it by messing with brightness and such. Then another couple of audio only.
Hi Vince, great repair. The large wheel with the spring is attached to the tuning capacitor, it is that which is turned to tune the radio. It is the position of the indicator strip relative to the position of the large wheel that's important. The other wheels simply provide a path and means of tensioning the string. The tuning capacitor assy is the clear plastic housing that can be seen on the opposite side of the PCB to the large wheel.
Just be sure to connect the ground to the tube if you decide to turn it on, in this case it was those prongs I'm guessing. Lots of noise. Might have to be with the lack of grounding on the signal cable you re-soldered. The braid seemed not to be connected.
Yes, I just read that on another comment. I thought it was bad reception in my house but I can clearly see the broken braid now. Thanks Vermilicious! 👍
I know this is an old reply to an old video, but perhaps you can explain why the braided sleeve must be connected to ground? It's around 31:00 where the signal cable gets loose.
@@rogieriusVideo signals are susceptible to electromagnetic noise, messing up the signal. The grounded braid in the cable stops that from happening (mostly).
Nice fix very retro always wanted one as a kid, probably would benefit from a recap to reduce noise, they have done well for forty years well done for saving another piece of tech from history.
The first connector (with the 4 wires), for the tube you were concerned about is the connection to the deflection coils on the tube, they will not hold a charge from the tube, although when powered up can give a fair walk. A B&W tube of that size is only about 14KV whereas a large screen colour is nearly 30K. With older CRT sets, best not to start twirling any preset pots as you have what’s called the B+ voltage and if that is too high, the tube can emit x rays!!!. Other risks of CRT is knocking the back of the neck off.
The CH-ON /TV-RADIO switch on the side is actually to permit charging of NiCd cells fitted in the battery compartment (someone will probably have beaten me to this). Used to be common on battery/mains radios back in the 1970s.
This so cool. It almost makes me want to tear up. It reminds me of my childhood when my grandfather drove Semi. I remember sitting in his Semi watch the football games with him.
you can use baking soda as a super glue activator, and also use it to build up a areas by putting super glue and sprinkling baking soda on, and repeating until the gap is filled in. much cheaper and just as rock hard. and you can sand to shape it, and paint it if needed.
That superglue job was phenomenal. You practically just threw those broken pieces onto the spindle and they placed perfectly. I figured you were gonna spend 20 minutes fitting those pieces together.
I remember my grandparents had one of those when I was a kid around the late 90s/00’s and they’ll have it on the front porch watching tv. Watching the video of you fixing it brings me my childhood memories going over there and watching my grandmother watch her soap opera shows while smoking and having her tea outside. 😅
I had one of these in the day, fitted it under the dash of my mgb roadster on a switch that turned off, when the ignition turned on to keep it legal. so I could watch the TV when parked. Worked great at the time.
Wow this brought back memories of when my dad bought the exact model and we were amazed how small and portable it was , we had it in our kitchen/ dining room
Use SERVISOL for switch cleaning, not IPA. IPA washes grease out of the switch and its needed to lube the clamp in the switch. Also get two household paint brushes, one Black bristle cheapo and a quality fine brush to clean out stuff from dust.
The switch on the side you cleaned first is for CHARGE. A battery charger is built in, and a lead acid battery was available for this model which sat in the battery compartment and positive was connected to a pole in a small recess. When in charge mode, tv and radio was inoperable. Lovely little set, I got mine in 1980 and it still works!
I think EXT is 'External' as in external antenna,and not 'Extension', and rod is the telescopic.Brilliant video btw,I was engrossed the whole time.I love watching folk using their hands and know-how to renovate things and get them working again.
I have something similar to this made by Radio Shack in the late 80s. I used to carry it in my work truck when I worked emergency service and was on standby with nothing to do. It still works, but the TV side can't pick up digital signals obviously.
Gosh, this takes me back to my parents' old Hitachi TV that needed a good minute to warm up after being turneod on. The image would slowly fade into life while the audio was there immediately.
I have one just like it, I had 2 but Dads one is still in its original box- from Dixons, probably 1982. Dads was less used than mine but both us were ‘campers’ and our one was in our tent!
Great fix, it looks so good. I was a bit nervous for you with the crt high voltage thingy. Q-Bond worked really well for me when I repaired quite a big chunk of cast aluminium on a cam cover…
Very cool! A elderly lady who was a youth leader at my church brought one of these and instantly hooked us kids' attention! :D .. after our lesson I remember watching the Wonder Woman tv show on it. Great memories!
Don’t ever sell yourself short my mate Vince if I ever had something that I needed fixed and it was a matter of life or death I would put my trust in you as you have a never give up attitude and are very knowledgeable 👍👍
I am pretty sure that EXT on the EXT / ROD switch stands for "external" rather than "extension". Also, as mentioned, you may want to investigate where the shield of that little coax that came off is supposed to go.
That's where I had a good laugh asa well as trying to take it apart without removing the knobs first. It's funny though how it reminds me my first steps when I was 18 and trying to fix things.
Hello,Vince, That selector switch on its side has 2 separate switches inside. All it does is connecting the middle pin either to the left pin or the right.
excellant repair i remember having a mini tv radio in my kitchen when i was married haha love taking things apart to figure out how they work hence why i am a mechanic now thanks for sharing new sub here.
My mum had one of these, used mainly on holidays but she also used it for her video work as a small monitor and she produced quite a lot of videos on the thing. Its use came to an end when I built up a PC for her that could handle full video input and she hooked a jogger board and second monitor to it and the poor old portable got chucked in the end as it was pretty knackered by this time.
That tube was actually a tube, it's a CRT, so it is a Cathode Ray Tube. It works by heating up a filament to emmit electrons that are accelerated towards the front of the tube using high voltage cathode and focused into a ray by an electromagnet (that big coil of wire arround the CRT) and the TV signal is an analog signal that it's split into a signal that modulates the strenght of electron ray to make a brighter or darker point on the screen and a signal that controls the sync of the electromagnets that divert the electron ray into a scanning motion left to right line by line. There is a phosphoros coating in the glass that emmits light when it's hit by the electrons.
I still have my NTV one from 1982, it has extra tech on it, red LED clock on it lol, been by my bed since then, only use it for the clock and radio, I tecently hooked up a SEGA megadrive on it, brilliant.
21:40 You have black lead on +12V and red lead on GND measuring -12V at the DC input so when you measure around the switch and see -0.5V and you say "nothing" it's actually 11.5V caused by the voltage drop through a dirty switch. Use the leads properly (black on GND, red on +12V and everything else).
i remember using one of these as a kid to watch startrek next gen in the 80s .... i had fun learning about electronics and getting a nintendo to run on it etc.. one thing i do remember is that it was heavy
When you rebuild the plastic with superglue reinforce it with more superglue and bicarbonate of soda inside the drum. You can use graphite with superglue too
I have a very similar Crown TV/Radio that still works other than no TV stations to watch. It has a rotary type TV tuning and Radio dial. I even have the service manual for it, when manufacturers still supplied manuals... An interesting video as I've never had mine apart...
Crown was never a premium brand, but it's nice to see that all of the faults are due to usage rather than component failure. Wear and tear faults mean that it was used and very much enjoyed way back when it was actually relevant. I expect it was a caravan dweller and amused the family on rainy days, which in the UK, was probably all of them. Pity it's now obsolete as a TV, but that's progress for you.
Great fix. Couple of new tools/techniques used which is good. I thought the 2 large dials on the top were what controlled the tuning (with the springs on them)
Watching the video back I think you are right as they are directly above the board. Cheers Emma, I thought it was the broken wheel that tuned it. Maybe I just got lucky with the placement then, or maybe the tuning is out (slightly shifted) on the TV. 👍👍👍👍
You're correct. The radio uses a fairly standard Matsushita tuning capacitor in a plastic case. The TV uses a potentiometer to provide a tuning control voltage which is sent over to the other (TV) PCB.
I bought one of those when I was a student in 1980 for £99. There were only about 4 similar units on the market at the time. I'm not sure if you know, but the shade around the screen can come off as it's only latched in. You just press it in a bit at the sides and pull it forward. No one ran them off batteries (given the choice) as they were quite power hungry for a portable device. Incidentally the CRT anode voltage is 6kV and the line scan boost voltage is around 200V DC (exposed on the main TV PCB) so you should be very careful when working on it even from batteries. The main message is only put one hand inside at once when on in TV mode.
I have a newer set like this it was ment to sit in the kitchen mounted over the microwave and you could even take it in the car and camping and stuff its a GE spacemaker I didn't get all the accesories with it so I just use it to watch tv when I workout on the treadmilll. It is a color tube set which is pretty cool!
When my girlfriend (now wife of 38 years) first moved in together we used one of these as our main TV for several months! That would have been 1982.....There's a chance it's still in a box in the loft... We had it on a fairly high sideboard and used to draw our 1960s bucket chairs as close as we could. Happy days.
I love the way you over play the "High Voltage" danger, on a set that hasn't been turned on in years! You are correct when you say you have little experience in the electronics field. But it seems you do in the field of overkill and drama!
I have one of those AM/FM VHF/UHF B&W set that was given to me at work back in 2000. I knew right away what novel thing I could use it for -- spinning through the analog dial tuner in the high UHF range to pick up cell phone conversations!
Love the "***" on the repaired little 1978 Crown portable TV/radio haha! And in case anyone's wondering, yes, you can get smaller "dedicated" RF modulators than a VCR :P I've got a Goodmans Quadro 905 5" B&W portable TV/clock/radio/cassette but the cassette door is broken, and judging by a photo I just saw online of one with it broken in the same way it seems to be a common problem.
The worst shock I have had and probably was the closest to electrocuting me was from an old CRT monitor I was working on. It had been years since it was plugged in and I stupidly assumed it would be discharged.... NEVER ASSUME. In the words of Dr. House "You know what you do when you make an assumption? You make an ass our of you and some guy named Umption."
Great video. I had a JVC equivalent (I think - this is a huge ask for memory). What people now do not realise, is that I could be the only person watching Wimbledon in the garden or the snooker final. You soon gained friends travelling to park with one of these :-)
Very Well Done Vince. Remember my dad bringing one of these home around 1978 when I was 10 years old and I thought it was amazing, so happy to see you fixing this as it brought back lovely memories. Have you heard from Roger as I haven't seen him on in a while? Mick 👍🍻
Cheers Mick 👍👍😎 Funnily enough I did at the end of last week. I believe he is a busy man job wise so it must be hard to find time for TH-cam. Hopefully he will have another vid ready soon 👍
Nice find Vince and great repair job. I wonder though if you have a signal strength problem too, I know you are going through many connections and convertions and this maybe the result, try it with a video recorder that generely work on channel 36 direct into the RF External connection... I bought something like this way back in the early 80's, it cost me £95 It had a 5" BW TV and Radio/Cassette (top loader.) I built a 4 digit LED Clock and hacked the front in between the TV and Cassette buttons. Buttons for the clock were placed above the clock on top. It looked very cool on my bedside table..... I swapped it latter for a Suzuki GT250 RAM Air system Motorcycle...... Well made up !..😁👌
10:08 in the grey plug with yellow blue and red and green wires are for the the horizontal and vertical deflection. They attach to the yoke on the tube neck. The yoke is the large coil wrapped around the tube neck. The other attachments on the tube are the tube base and the E.H.T. cap (the red wire from the black line output transformer leads to the E.H.T. cap). The E.H.T. cap has a very high voltage (several thousand volts) on it when running. This voltage can be stored in the tube for a long time so great care should be used when removing the E.H.T. cap. Maybe discharge it with a screwdriver to the chassis or the outer "aquadag" coating on the tube body while holding the insulated handle of the screwdriver. There will also be an earth wire on the "aquadag" coating running to the chassis or tube base. Well done on the tuning dial cord - they can be very tricky. Would be interesting to know if it still works or whether components have started to fail through re-use after sitting around unpowered for who knows how long. Maybe post something if it goes faulty?
Man that's nuts running a pre 2020 PS5 console into a 1978 portable TV - radio system. Both timelines couldn't be further from one another in the concepts of time and progress here. But in a rare form they're aligned here for all of us to see. These TV - radio systems were still sold in the 1980's via Tandy/Radio Shack among others although not as big/sturdy built. Get some mates to play your PS5 like this and it'll be the talk of the town here. That Radio TV system is as old as me and is a sheer piece of electronic ingenuity as well. Nice fix.
Nice repair, the TV reminds me a bit of the Commodore SX64 in appearance. I wonder if Commodore took inspiration, or perhaps the design was bought from the same design buro. Also... I suspect Q-bond is just coloured baking soda and superglue.
All the power connectors have built in switches (mains, 12v barrel jack) so that when a power source is connected it disconnects from the battery. Often the internal switches in the sockets go bad.

1st class video to watch thank you take care kind regards from me kenneth
Gosh, this takes me back to my parents' old Hitachi TV that needed a good minute to warm up after being turneod on. The image would slowly fade into life while the audio was there immediately.
Wow thatt make's me feel old Vince . Its crazy how big that was, and now you can watch tv on your smart device, thanks for the video
I have one just like it, I had 2 but Dads one is still in its original box- from Dixons, probably 1982. Dads was less used than mine but both us were ‘campers’ and our one was in our tent!
Great fix, it looks so good. I was a bit nervous for you with the crt high voltage thingy. Q-Bond worked really well for me when I repaired quite a big chunk of cast aluminium on a cam cover…
Very cool! A elderly lady who was a youth leader at my church brought one of these and instantly hooked us kids' attention! :D .. after our lesson I remember watching the Wonder Woman tv show on it. Great memories!
Mr. Vince you're a wild man, heading into any unknown territory.
Nice to watch your vids.
Hahaha, thanks Bo 👍👍
You sir , have the patience of a saint. Roll on the next video and 1 million subs.
Very nice fix, we had a portable color tv when I was a kid that we'd hook the nintendo up to sometimes depending on where we wanted to play
Thanks Jimmothy 👍👍
@@Mymatevince thanks for hooking up the nintendo or what u suckin on??
Don’t ever sell yourself short my mate Vince if I ever had something that I needed fixed and it was a matter of life or death I would put my trust in you as you have a never give up attitude and are very knowledgeable 👍👍
I am pretty sure that EXT on the EXT / ROD switch stands for "external" rather than "extension". Also, as mentioned, you may want to investigate where the shield of that little coax that came off is supposed to go.
Correct (on the EXT issue).
That's where I had a good laugh asa well as trying to take it apart without removing the knobs first. It's funny though how it reminds me my first steps when I was 18 and trying to fix things.
Hello,Vince,
That selector switch on its side has 2 separate switches inside. All it does is connecting the middle pin either to the left pin or the right.
excellant repair i remember having a mini tv radio in my kitchen when i was married haha love taking things apart to figure out how they work hence why i am a mechanic now thanks for sharing new sub here.
A fantastic restoration of a rare retro piece of kit there Vince! Great job!
My mum had one of these, used mainly on holidays but she also used it for her video work as a small monitor and she produced quite a lot of videos on the thing. Its use came to an end when I built up a PC for her that could handle full video input and she hooked a jogger board and second monitor to it and the poor old portable got chucked in the end as it was pretty knackered by this time.
Your mum had good taste Ian, this portable TV and the Amstrad Notepad. Hope you keeping well buddy 👍👍👍
Man, seeing the PS5 playing on something from the year i was born is awesome. Great repair, well done. Cheers!
That tube was actually a tube, it's a CRT, so it is a Cathode Ray Tube. It works by heating up a filament to emmit electrons that are accelerated towards the front of the tube using high voltage cathode and focused into a ray by an electromagnet (that big coil of wire arround the CRT) and the TV signal is an analog signal that it's split into a signal that modulates the strenght of electron ray to make a brighter or darker point on the screen and a signal that controls the sync of the electromagnets that divert the electron ray into a scanning motion left to right line by line. There is a phosphoros coating in the glass that emmits light when it's hit by the electrons.
Here in the UK,the cathode ray tube is just called the tube and the other vacuum devices are called (thermionic) valves.
I had one of those, used it to play ps1 games when I went to uni in the late 90s. I've still got the ariel from it!
I really love watching you Vince
I had one of these back in 1983, it was the TV I used with my Zx Spectrum. No colour for me just glorious black and white.
Been watching this m8 since 2017 never gets old keep at it Vince
Hi Vince. great and interesting repair. to fill holes in plastic or as a strengthener I use super glue and bicarbonate of soda amazing results.
I still have my NTV one from 1982, it has extra tech on it, red LED clock on it lol, been by my bed since then, only use it for the clock and radio, I tecently hooked up a SEGA megadrive on it, brilliant.
This is so cool, as a child we had a similar unit in our family van and had our NES hooked up to it for road trips
21:40 You have black lead on +12V and red lead on GND measuring -12V at the DC input so when you measure around the switch and see -0.5V and you say "nothing" it's actually 11.5V caused by the voltage drop through a dirty switch. Use the leads properly (black on GND, red on +12V and everything else).
i remember using one of these as a kid to watch startrek next gen in the 80s .... i had fun learning about electronics and getting a nintendo to run on it etc.. one thing i do remember is that it was heavy
When you rebuild the plastic with superglue reinforce it with more superglue and bicarbonate of soda inside the drum. You can use graphite with superglue too
I have a very similar Crown TV/Radio that still works other than no TV stations to watch.
It has a rotary type TV tuning and Radio dial.
I even have the service manual for it, when manufacturers still supplied manuals...
An interesting video as I've never had mine apart...
Crown was never a premium brand, but it's nice to see that all of the faults are due to usage rather
than component failure. Wear and tear faults mean that it was used and very much enjoyed way
back when it was actually relevant. I expect it was a caravan dweller and amused the family on rainy
days, which in the UK, was probably all of them.
Pity it's now obsolete as a TV, but that's progress for you.
Great fix. Couple of new tools/techniques used which is good. I thought the 2 large dials on the top were what controlled the tuning (with the springs on them)
Watching the video back I think you are right as they are directly above the board. Cheers Emma, I thought it was the broken wheel that tuned it. Maybe I just got lucky with the placement then, or maybe the tuning is out (slightly shifted) on the TV. 👍👍👍👍
You're correct. The radio uses a fairly standard Matsushita tuning capacitor in a plastic case. The TV uses a potentiometer to provide a tuning control voltage which is sent over to the other (TV) PCB.
U can glue little magnet for this antenna to stay in place when closed
I bought one of those when I was a student in 1980 for £99. There were only about 4 similar units on the market at the time. I'm not sure if you know, but the shade around the screen can come off as it's only latched in. You just press it in a bit at the sides and pull it forward. No one ran them off batteries (given the choice) as they were quite power hungry for a portable device. Incidentally the CRT anode voltage is 6kV and the line scan boost voltage is around 200V DC (exposed on the main TV PCB) so you should be very careful when working on it even from batteries. The main message is only put one hand inside at once when on in TV mode.
Thanks John, didn't know about the shade. Cheers for the history and tips/advice 👍👍👍📺
A lot of money back then but it was state of the art nevertheless..
This is really neat. And somehow really relaxing watching you do these. Maybe it's the nostalgia.. maybe.
I have a newer set like this
it was ment to sit in the kitchen mounted over the microwave and you could even take it in the car and camping and stuff its a GE spacemaker
I didn't get all the accesories with it so I just use it to watch tv when I workout on the treadmilll. It is a color tube set which is pretty cool!
Great work. Thank you. I wonder if you may find any signal on TV with rod.
Absolutely brilliant!, I really admire your determination and analytical skills! Made my day and week and month!1 thank you soooo much!
When my girlfriend (now wife of 38 years) first moved in together we used one of these as our main TV for several months! That would have been 1982.....There's a chance it's still in a box in the loft...
We had it on a fairly high sideboard and used to draw our 1960s bucket chairs as close as we could.
Happy days.
smelling the same poopy wife smell every morning for almost 40 years?!?! what a champ.
Mine had a tape deck too you have so much patience Vince well done 👍👍👍
Superb work vince and the tuner thing worked ot well .
You make this look so easy! Excellent as usual...
I love the way you over play the "High Voltage" danger, on a set that hasn't been turned on in years! You are correct when you say you have little experience in the electronics field. But it seems you do in the field of overkill and drama!
I have one of those AM/FM VHF/UHF B&W set that was given to me at work back in 2000. I knew right away what novel thing I could use it for -- spinning through the analog dial tuner in the high UHF range to pick up cell phone conversations!
Love the "***" on the repaired little 1978 Crown portable TV/radio haha! And in case anyone's wondering, yes, you can get smaller "dedicated" RF modulators than a VCR :P
I've got a Goodmans Quadro 905 5" B&W portable TV/clock/radio/cassette but the cassette door is broken, and judging by a photo I just saw online of one with it broken in the same way it seems to be a common problem.
The worst shock I have had and probably was the closest to electrocuting me was from an old CRT monitor I was working on. It had been years since it was plugged in and I stupidly assumed it would be discharged.... NEVER ASSUME. In the words of Dr. House "You know what you do when you make an assumption? You make an ass our of you and some guy named Umption."
I really like these old units. Brilliant.
Wow. I used to have one of those!
Great vid. Thank you.
Also, the weird little receptacle with a door was meant as a store for a mono headphone.
Keep up the good work fella and stay safe!
Simply Beautiful and a delight to watch.
Made in Japan, very good stuff. I think you can easily composite mod this one.
That brings back memories for me. I had the superior JVC model which also had a cassette player in it.
Great video. I had a JVC equivalent (I think - this is a huge ask for memory). What people now do not realise, is that I could be the only person watching Wimbledon in the garden or the snooker final. You soon gained friends travelling to park with one of these :-)
Very Well Done Vince. Remember my dad bringing one of these home around 1978 when I was 10 years old and I thought it was amazing, so happy to see you fixing this as it brought back lovely memories. Have you heard from Roger as I haven't seen him on in a while? Mick 👍🍻
Cheers Mick 👍👍😎 Funnily enough I did at the end of last week. I believe he is a busy man job wise so it must be hard to find time for TH-cam. Hopefully he will have another vid ready soon 👍
liar liar dad on fire
Just found your channel yesterday - superb! Binging now!
Nice find Vince and great repair job. I wonder though if you have a signal strength problem too, I know you are going through many connections and convertions and this maybe the result, try it with a video recorder that generely work on channel 36 direct into the RF External connection...
I bought something like this way back in the early 80's, it cost me £95
It had a 5" BW TV and Radio/Cassette (top loader.)
I built a 4 digit LED Clock and hacked the front in between the TV and Cassette buttons.
Buttons for the clock were placed above the clock on top.
It looked very cool on my bedside table.....
I swapped it latter for a Suzuki GT250 RAM Air system Motorcycle...... Well made up !..😁👌
Nice repair Vince. Thankfully no shocking flyback transformer fun 🌩⚠🙂
Nice long Saturday Video before work tonight Cheers Vince 👍❤️
Nice one Jinxy 👍👍
You can get an HDMI to RF converter which allows you to use an old telly as a computer monitor.
10:08 in the grey plug with yellow blue and red and green wires are for the the horizontal and vertical deflection. They attach to the yoke on the tube neck. The yoke is the large coil wrapped around the tube neck. The other attachments on the tube are the tube base and the E.H.T. cap (the red wire from the black line output transformer leads to the E.H.T. cap). The E.H.T. cap has a very high voltage (several thousand volts) on it when running. This voltage can be stored in the tube for a long time so great care should be used when removing the E.H.T. cap. Maybe discharge it with a screwdriver to the chassis or the outer "aquadag" coating on the tube body while holding the insulated handle of the screwdriver. There will also be an earth wire on the "aquadag" coating running to the chassis or tube base. Well done on the tuning dial cord - they can be very tricky. Would be interesting to know if it still works or whether components have started to fail through re-use after sitting around unpowered for who knows how long. Maybe post something if it goes faulty?
Man that's nuts running a pre 2020 PS5 console into a 1978 portable TV - radio system. Both timelines couldn't be further from one another in the concepts of time and progress here. But in a rare form they're aligned here for all of us to see. These TV - radio systems were still sold in the 1980's via Tandy/Radio Shack among others although not as big/sturdy built. Get some mates to play your PS5 like this and it'll be the talk of the town here. That Radio TV system is as old as me and is a sheer piece of electronic ingenuity as well. Nice fix.
Nice repair, the TV reminds me a bit of the Commodore SX64 in appearance. I wonder if Commodore took inspiration, or perhaps the design was bought from the same design buro.
Also... I suspect Q-bond is just coloured baking soda and superglue.
