- A customer got in touch with David at LCD TV Repair and he turned this customer on to me and the customer sent his DVD-VCR to me to be repaired. It was just a mater of cleaning the oxidized, tarnished mode select switch (rotary encoder) and this unit is back up and running, major disassembly though!

Absolutely perfect video!!! Exactly what we all need to know to do it our selves. The 3 Idiots who thumbs downed it are exactly what is wrong with this world. Thank you very much.
You always make good quality videos. This video shows how much time and disassembly it took just to clean a switch. This is one reason why no one wants to work on these.

Nice video, I have three old VCR's , they work great and All differ kind. You, get 5 out 5 winner in my book
When fixing VCRs i have always just used a qtip to clean the encoder and it has always works
Thank you. With your help I was able to get my Magnavox VCR/DVD recorder/dubber working again.
A rotary mode switch is perhaps one of the biggest trouble spots in any modern VCR. When the contacts become oxidized, it develops high resistance and malfunctions. No need to replace a part unless it's shorted, open or damaged in some way. A simple cleanup is all that's needed in many cases.
Great results and no parts needed so a reasonably inexpensive repair as well - customer will be happy.
*wonderful repair! I would feel lucky if I got this video some thirty years ago. The machine is really in good shape.*
You all prolly dont care but does anybody know a trick to log back into an instagram account??
I stupidly forgot my login password. I love any tips you can offer me.
@Orion Jaxton Instablaster =)
@Conor Ayaan thanks for your reply. I found the site through google and I'm in the hacking process atm.
Seems to take a while so I will reply here later when my account password hopefully is recovered.
@Conor Ayaan it worked and I actually got access to my account again. I am so happy:D
Thanks so much, you saved my account :D
@Orion Jaxton you are welcome xD
Steve you should be an instructor in a trade school. You are a natural teacher.
Man in not too many years guys like this probably won't exist.
I have a Magnavox combo very similar to this one with the nearly identical problem this one displayed. My fix was far simpler and faster though: the VCR part hadn't been used in years and the head was froze up. All I had to do was spin it clockwise a bunch of times till it spun freely. Inserted my tape and all functions worked as they should. Do this before you start to disassemble the unit and hopefully you'll get the same results.
Excellent video for vhs repairing! Thanks for interesting vid.
Thanks so much for your repair videos. Keep up the great work!
Jeez, magnificent magnavox...
I love your videos very much!
Nice Vid. Was able to clean the mode switch without desoldering anything. Just tilt the VCR unit up 3/4". Used a GC Electronics fiberglass 'pencil brush', acetone, Q-tips, and dielectric grease. Rotor popped right back on. Never test any VCR with the top cover off unless the room is fairly dark. Light messes up the IR or opto-transistor sensors.
Do you have to remove the entire control board? Could you explain your procedure in a bit more detail? Not sure I get the 3/4" tilt. Do you have to pry the rotor off?
Yes. That works and that's exactly how I service those Funai combos.
Stefan do you happen to have a video of that method? Thanks.
@@TheVCRKing do you have a video of that repair? Thanks.
@@JasonPurdyNH Unfortunately I do not but I did film a similar repair video with a Funai built VCR.

Your awesome!
ty..
Hello. I am currently trying to fix my VCR using the same method in this video. I am wondering if there is another option to clean that spot you used the stainless steel toothbrush on.
Some of my vcrs likes to eat my tapes, but I don't mind at all!
Who's the handsome fellow on the video tape? :P
Thanks for your amazing insightful videos. Where do you get your service manuals? I have a Magnavox MDR161V /F7 that looks virtually identical to this ZV427MG9 A. that a schematic would be extremely helpful for. I owned and ran a 50 year old one man Radio/TV/everything repair shop that I shut down in 2000. I sold off all of my manuals and most of my test equipment and lots of stock. I still have a lot of new VCR parts (ASTI heads, gears, components, etc.), if you're ever looking.
Actually, i just found the manual so you can disregard.
The plastic arm that open the front flat door that opens automatically when tape is ejected came off. How you reattach it. Funai combo
Can you tell me if the Mode Switch can cause the tape to get hung up on the tape transport mechanism upon ejection? The VCR plays tapes OK, it's just that upon pressing Eject, the tape comes up and is pushed out of the VCR but the tape is getting hung up on something inside the tape transport mechanism.
how much do you take for this ???
Hi please tell me if you still fixing vcr I have a Really nice Panasonic vcr needs to be fixed

Hello. I have a lg dvd-vhs combo vcr. The first 10-15 minutes show bad. Then it gets better. I tried many different cassettes same problem. I wonder what the problem might be. Sorry google translation
So I have a magnavox dc220mw9 and the cover for the dvd won’t stay closed. I’m wondering you can show me the inside of the font cover to see if the spring is in the wrong spot. It just flips open until I manually close it. Or if there is something it’s supposed to latch in the inside to spring close. Can you help???
If you have the front detached from the unit does the door stay closed?
i have the same unit and it wont turn on anymore... some one said there is a fuse inside that might have blown.??? i didnt see a fuse in this video when you took it apart....any thoughts?
The fuse is on the power supply board under the DVD mechanism.
I need this repair for my exact same VCR DVD player. Can I send to you to repair?
YES you can. DM me on Facebook, twitter , or Instagram.
How does one get in touch with you for a repair? I have the same unit that plays, then goes into sleep mode.
Send me an email norcal715videos@gmail.com
I had the same problem. I then cleaned the rotary encoder and now it loads and plays for seven seconds and turns off. I turn it back on and it ejects the tape. It runs for exactly seven seconds every time. It can fast forward OK. Any ideas of what the problem is? Maybe no pulse from the capstan? thx
Check the reel rotation IR LED and detector. th-cam.com/video/xPXMwdAnwtg/w-d-xo.html at 11:45
Thank you. I followed the IR LED and dectector proceedure and still have the same problem. I used a cell phone and can see the LED is lit and if I block the receptors the mechanisms do respond. I even did the cap and transiter on the th-cam.com/video/btGhqj5RwB4/w-d-xo.html video. Any ideas? Thanks again
Follow up...I decided to tear into it again and solder all the contacts for the IR LED and IR receivers on the backside of the board. That fixed it. Thank you.
What would cause a Symphonic SC313B combo TV/VCR to shut down after 5-10 seconds of being turned on. If I put a tape in it will play the tape no problems. As soon as I hit the Stop button 5-10 secs it will turn off the TV. The only trick I found is if I disconnect the power cord and wait for lets say 30 mins, then plug the cord back in with a tape in it and hold the tape from coming out it will stay on. As soon as I eject the tape the TV shuts off or if I just manually shut off the TV then turn it back on it will shut off in 5-10 seconds.
I have to repeat the process of unplugging the TV for some period of time then power up with a tape in it and hold it so it won't come out then the TV will work again.
Any clues what the fix is?
Probably a mode select switch or cassette in-out switch issue. It sounds like it is trying to eject further and that is what is shutting it off.
@@norcal715 The interesting thing is the only time the TV stays on is when it's playing a tape.
Where can I send you please?
Steve how can you be contacted? Thanks

NEVER !! EVER !! use cotton swabs aka qtips to clean video heads this will cause damage, you can however use them to clean tape paths etc. also check the auto head cleaner to see if its dirty.... actually scratch that, just remove it completely and toss it in the garbage. you'll do the customer a big favor.
Only been using cotton swabs to clean video heads for the better part of 40 years. I think I will stick to what works for me. I will continue to discard the head cleaners, unless they are in pristine condition.
@@norcal715 you got lucky, in my experience ive seen soo many chipped video heads from folks vcrs from them using qtips and having to replace them. back in the day. blank paper soaked in isopropyl alcohol works best.
That is not good put that in mode switches it causes not to lasting longer on not being cleaned
What???
Please clarify your question/statement!
Are you referring to the dielectric grease?
If so, I have only been using it for about 40 years now and I have several VCRs of my own that are over 30+ years old and have not had to service the mode select switch after the dielectric grease treatment. I have had to replace belts and idlers though. There is no fix for consumable items.
Terrible design! Funai made the last VCRs in 2015. Cheap parts and stupid quality- marked the end of VHS. Our magnavox combo drive had a dirty center tape sensor. Cleaned with alcohol and works perfect. You should remove that foam head cleaner. It's very problematic
IS ruins motor bro you give so much
??? What???
