- Panasonic DMR EZ48V DVD/VHS recorder U80 and U81 faults cured.
This video will only be of interest to someone wanting to know how to strip down of a Panasonic DMR EZ48V DVD-VHS player/recorder to get to the faulty PCB and replace the failing capacitors that causes the U80 and U81 faults.
The reason that I made this video is that when I found someone on eBay selling a ‘Fix’ for this fault they said that it involved a fair bit of dismantling and that anyone not comfortable with a significant amount of dismantling may not want to carry out the repair. The only tools you need are a Philips screwdriver, a small flat blade screwdriver, a soldering iron and a small pair of wire cutters. I use a solder sucker but you can manage without one. Once you know what has to be done and how to do it, it should probably take around 30 to 45 minutes to complete the job. In this video you’re with me for the first time that I’ve carried out this repair.
I purchase the fixing kit, which comprises of nine electrolytic capacitors from Steve who trades on eBay under the store name of ‘wizardfest’ the nine capacitors cost little more than a cup of coffee and Steve emailed four pages of instructions.
I don’t know Steve and I’ve never dealt with wizardfest before but he has a good rating (November 2017) and his ‘kit’ works for me, the delivery was fast and the instructions are good.
You can contact Steve at vtsrepairs@tiscali.co.uk The repair kit has the item number as #172638133006 and you can find it on eBay by entering that number.
Maybe you’ll let him know where you found the info?
I hope this helps you.
Kind Regards . . . Andy. - วิทยาศาสตร์และเทคโนโลยี
Just replaced the same components on an EZ47V (In Australia) same machine no Scart and found this video invaluable for the dismantling/reassembly . I also sourced components from the same supplier. Thanks again.
That's great I love it when I can say that I've been able to help someone and somehow it's even better when it's someone on the other side of the world (not that the world is a very big place anymore)We'll probably never meet my friend but I'm really pleased that I could help you. This is good and the way TH-cam should be used, to help each other.Kind Regards . . . Andy
Things like this are becoming a lost art Andy. Good to see you are still tinkering. Every good man enjoys a good tinker
I have two of these Panasonic EZ series DMRs. Both have been dead for over a year with the code "F60" I may have the courage to attempt a disassembly for capacitor replacement now that I have seen your video. It was very informative and I enjoyed it immensely. Thank you.
Thanks for the video.... glad to see you are still on the right side of the turf. Hope to see more from you, always informative. Thanks again.
Just checked your channel and found this video you produced. I hope that it is a sign that you have returned. If its just a quirk and you won't be back for a while it was good to hear your voice again, and enjoy your free retirement time. 73
Very helpful video; my Panasonic had "died", and I got the bits from Wizardfest, and had no problems other than that the DVD player arrangement on mine had far more screws holding it than the four on your model. It took a while to work out what to undo in what order - the equipment now works again. Thank you very much for posting this.
Well done David and thanks for letting my know, it's always nice to know that I've helped someone.All the best . . . Andy
thanks for posting this mate.. .my dmr ex75 has been lying dormant for a few years with the u81 fault so i'm going to have a go at fixing it. Just bought the parts from the guy right now.
Fantastic video. Found it after I'd done some disassembly, but very helpful for putting it all back together.
Unfortunately, I didn't know about the replacement kit. So I ordered just 3 capacitors from Mouser and replace them (which were bulging); would have been better to do more while the unit was torn apart.
Yes, a slightly complicated tear-down, but really not that bad... and this video makes it easy! Thank you.
Hi Andy, Glad to see you're still around! I love all your tube radio videos (valve). This is a bit more modern than what I'm used to but I'll enjoy watching nonetheless. Take care, Gary
Hi Gary I was sure that I responded to your comment but I don't see it here. I was brought up on the old body-tip-spot resistors (carbon composite, what we used to call carbon compost ) And when electrolytic capacitors used to fail they'd blow silver foil and oily wax all over the place. I used to love the smell of the old selenium (metal plate) rectifiers when they failed, such a distinctive aroma. This modern stuff doesn't even fail with a satisfying flash and bang. I can remember very often to predict the fault simply by the smell you got when you took the back off the set. All the best . . . Andy
Congratulations on making the best instruction video I have ever seen on TH-cam. Well done
Isn't that nice, thank you very much for the comment.Kind Regards . . . Andy
Hello Andy,welcome back as a old TV and VCR technician cap problems where grist for mill in my day full marks Mate for you repair.
Hi Eddy I started off in radio and TV with body-tip-spot resistors and capacitors were called 'condensers' remember when they used to explode in spectacular fashion! Silver foil and guff all over the place. I used to love the smell of a burnt out Selenium rectifier, so distinctive. As for this surface-mounted stuff, I don't fancy messing about with some of the million pin ic's that I see in the modern kit. All the very best . . . Andy
Hi Andy - great video - many thanks! I have a similar model of Panasonic, and it had the U81 fault. After watching your video, I decided to have a try at fixing it. When I dismantled the unit, 5 of the specified capacitors were visibly blown, so I ordered the parts from Wizardfest and set to it. I haven't soldered a PCB for >30 years, so didn't make a very good job first time round. I think the main problem was that my soldering iron was probably too big, and it broke a couple of the solder pads off when I tried to remove the old blown capacitors. As expected, when I put it together it still didn't work, but now gave the 'Please Wait' fault. Not wanting to admit defeat, I got a new soldering iron for Xmas with a finer tip. I did research how to repair the solder pads, but it looked like a difficult skill to master, so I decided to bodge it instead. On the bad joints, I traced the track on the PCB to the next joint, and soldered a piece of wire from the badly jointed capacitor leg to the next solder joint along the track. It's not pretty, but when I put it back together and tried it, it all worked perfectly :) Many thanks for giving me the confidence to have a go.
I just began viewing yr video 3 years later, as I have same fault with my Panasonic HDD box.. You had done a great talk through of dismantling yr player., I think if/when I look to do mine it would be best to record it on mobile phone as writing notes are arduous if you keep drawing diagrams to show where different screws come out., Or alternatively I will first see if I can get a replacement board 😬..Best wishes Michael.👏👍🌞 Update; I purchased a power board for £44 off eBay..
That brings back pleasant memories for me. I was a VCR/Telephone/TV technician way back in the late 80s and early 90s. My co-worker got all the TVs, so I only worked on my own and a couple for the boss. Most of my work was small items and VCRs. I am amazed at how the modern item is slightly trickier - the cost cutting has resulted in some minor changes that cause just a bit more trouble to you. Just before you said it, I thought "pick up the door before installing the front." I've put on several just like that.
I can remember a million years ago fixing a pilot light on a mains powered Bakelite radio, the bulb was flickering as it was lose. I reached in to turn it and caught my wrist on the top cap (anode) on one of the valves, my reaction was of course to whip my arm back at the speed of light, the radio went over me head and smashed to pieces on the wall behind me! I can still remember the two pin plug just missing me face. I think my boss gave the customer a transistor radio to replace it. Moral of the story, always disconnect the mains first.All the best . . Andy
Excellent video. For those attempting this repair it's not that difficult, go for it!
Great video Andy and good to see you back on TH-cam.
Thanks Miles. I do like making the videos but boy I can't tell you how many times Photoshop crashed on me!!! it's not all progress is it?Regards . . . Andy
Good to see your back!
Thinking about you and worried about not seeing you,,glad to see you, keep them coming
Hi Dennis life is so busy I don't know how I ever had the time to go to work, I just don't have much time to make videos. Been busy doing some property developing and house designing which has taken a huge amount of time but it's loads of fun.Thanks for the comment. all the best . . Andy
Nice to see you back and hope you are well, Jimmie
Thanks Jimmie Yep I'm fine thanks and long may it continue I hope all's well in the world with you and yours. All the best . . . Andy
Many thanks for the best 'how to' video I've seen. With your help I've managed to repair my DVD-VHS player using the parts supplied by Wizardfest. My particular problem was the 'Please Wait' message after switching on which it has also cured. After completing the re-assembly and switching on, I found that I needed to reload the firmware which I did using a disk I'd bought from the web some time ago. Thanks again, Andy. I need to tackle a Sony LBT-A490 Hi-Fi unit with a failed tape player so I'll wait for your video....
Hi and thanks for the feedback, I'm really pleased that the video helped you. Don't hold your breath on the Sony though, maybe someone else has one they might fix. Thanks again, it's always nice to hear that it's been worth while.Kind Regards. . . Andy
Hi Andy,
Thank you, thank you, thank you! I have a Panasonic DVD Recorder that stopped working. It is a little different model than yours. Mine is the DMR-EZ485V. But I followed your directions and I had to replace four capacitors. I got it all done without any problems, thanks to your video. It now works like new. Thanks again.
Hello, I have this exact model too with a F60 error code. None of the suspect capacitors are bulging but think they should be replaced to get it working. Which 4 did you replace, if you remember. Thanks!
Great to see your still making videos Andy!
Hi, I need to build a time machine and generate a few more hours in the day. Man it took over 13 hours to upload this video! it's not all progress is it. Thanks for looking in.Kind regards . . Andy
Wow Andy, that's been a long time since I saw a video from you.
Nice to hear from you again!
Greetings from Nedeland.
Thanks Ben, you're right it's been a long time since I made a video but I was so pleased to find the guy on eBay offering a repair kit I just couldn't resist getting into the recorder and fixing it.I have no idea where in the circuit the various capacitors are but replacing them has certainly cure the problem.All the very best from the UK.Kind Regards . . . Andy gw0jxm
Welcome back Andy!
Hi Andy, welcome back and I hope you are well. I done a repair on a Panasonic sa-hx150, monday just gone it had no fault codes apart from saying "no disk" anyway voltages were all okay, the carriage switches was okay, after further checks it turned out to be the spindle motor. Anyway I could not get a motor but could get the carriage assembly "bsr=a1 i think it was" for silly money so i ended up taking the motor apart i was able to retention the fine metal "no carbon" brushes and re-lubed it etc, and after a hassle re-crimping the 1mm case "plus hot glue" lol. All worked fine after and customer was over the moon being as it was a home theatre dvd system complete with 5x160watt "D-class" power amps and 1x200watt sub amp. Take care, Paul from London
Well done Paul, it's always nice to win isn't it.Kind Regards . . . Andy
What a great video! With your video and the fixing kit of nine capacitors from Steve, I have just repaired my Panasonic DMR EZ48V DVD/VHS recorder. I have never done anything like this before so well pleased when it worked.
Saw your post and I was grinning ear to ear. Thanks for the new video!
Thanks for taking an interest in the video, I really hope that it helps someone with this particular problem. All the best . . . Andy
Thank you Andy. I have a DMR-EZ475V (I'm in the U.S and don't know if my model is U.S. only) and even though the models are not the same and the inside is somewhat different than yours, your video was a tremendous help. Kept me from going after the front panel of mine with a hammer and blow torch. I can't find a pre made parts kit like you were able to, but I can piece one together. Thanks again for your video and help!
I have the DMR-Z48V model and live in the US. The start up o's come on but then the screen goes blank. I can hear it trying to run inside but it won't play or eject. Currently we have a DVD stuck inside. Any advice?
Very good. Just fixed my U81 error code on my Panasonic DMR-EZ48V VHS-DVD Recorder
Ordered my set from ebay today. Thankyou for a great tutorial.
How did it turn out?
Nice to see a new vid from you Andy ! I don't have such a device to fix personally, but I have a Toshiba DVD player in which I have fixed two different faults, both due to electrolytics failing in a short circuit kind of way. Unlike you though, I didn't go to the trouble of recording what I did for other folks' benefit - well done. Hope to see more from you, inspite of the time it takes to upload stuff.....cheers from Dave (GW4FIC)
Hi Dave I've found TH-cam and the internet so helpful over the years. I think it's good to try and put something back into the system, I don't know how many folk this video will help but hey if it helps just one person I'll be very happy.all the best . . Andy gw0jxm
We both pre-date the WWW (and the internet!) - what on earth did we do for information like this back then ? I simply can't remember...and yes, YT has given me so much help and interest in new things I'd never have looked at without it....73, Dave
Para los que hablamos Español nos has ayudado ya que está marca da ese mismo problema en otros modelos
Concretamente yo tengo el Dmr-EX77 Y no tiene el repuesto para esa falla sí que se puede reparar cambiando todos los condensadores de la placa digital/analógico son más de 20 pero el resultado es positivo
Sólo para personas con base electrónica y algunas herramientas
Thank you for the Video so much! I had different problem with same unit and I didnt know how to release these metal pins from VHS board ))) THANK YOU for details and effort you put in this video!
Thanks, glad to have helped. Kind Regards . . Andy
First Class video ,Thanks it was very helpful
Thanks for the useful video, I bought the kit from wizardfest on ebay, arrived very quickly indeed. Thanks for the recommendation, my DMR EZ47V now works once again.
Hi glad to hear it worked for you. Did you follow these exact instructions? Thanks
Hey Andy, enjoyed this video very much. Hope you do more of them. Between this video and the video before this I earned my extra class license. Don't really have a way to use it yet, but we're working on it. Hope you and Sophie are doing well.
Best regards, Rick.
Hi Rick thanks for the kind words, I appreciate your comments. I haven't had much time for video making (or watching) as we've just been busy having fun and doing some property developing with buying and selling houses. Man I love to be doing something exciting and pushing the boundaries a bit. How did we ever have the time to go to work? Well done on the licence. We're planning a move one hour up the road to Aberystwyth, we've bought an huge old 1950's building with fabulous sea views and loads of space for aerials so I might be getting back on the air once we've demolished the existing concrete block building and built a well insulated house there. As for this video I think I might make snappier version of it as I've just received the second kit to fix the other recorder that has the same fault, I figure as I now know what I'm doing I can make a better video.All the very best to you and the family and a bit early but have a Happy Christmas. 73's . . Andy
I figured you were busy, and I'm glad you're having fun with it. And good luck with the move, might make an interesting video. I'm doing part-time work for a guy who has some very interesting patents. One of them is putting nitrogen in water, to fertilize plants, without using any chemicals. Another one of his patents is a process for cleaning the water in swimming pools without using any chemicals. I build and repair these units and more, and have some influence in design. But I would like to be a little busier so I have been thinking about teaching at the senior center or at a junior college, but I'm not quite sure what the subject would be. I need to go there and find out what they need. I used to be a course developer and instructor for Nortel Networks, besides being a software engineer. I'm glad to hear things are going well with you'll.
Best regards Rick
Hi Rick good to hear about the interesting work. As for teaching, teaching us old farts how to undo the damage that Windows 10 updates do would be great. I bought a new printer as the previous update killed my HP printer and now the latest update has immobilised the new HP Printer, man its a pain. When Windows 10 first forced itself on us I lost all of the text from the dropdown menus in Photoshop, about a month or two later they reappeared but the last update has robbed them again. Boy it really makes my lose heart. All the best . . . Andy
I'm still on Windows 7 and plan to stay there.
VTS repairs no longer supplies the kit for the USA market. I sent them a email and this was their response. "Sorry but we don't sell kits to the US as your models are internally different.
Sorry but you'll need to source any parts locally.
Kind regards
Sue " So please let me know if any of you know who on Ebay or elsewhere carries the capacitors that Andy talks about in his video. Great video Andy.
Hi there, Wow! that looks like quite a job, but being that this was back in 2017 and I'm viewing it just now sure does help.
Kind of a shame I didnt see it back then as looking at your power board you can see the caps that were Bulged on the tops. I bet those were the ones that were giving you the problem of the error codes, the rest probably were ok - but you would need a ESR meter to test the resistance value to be sure. As the caps dry out the resistance goes up and thats the problem most of the time in power circuts. Again a job well done and you saved it from out of the land fill.
Thanks. Especially helpful in separating the psu board from the vcr/video processor.
Hi Colin i hope you got it all sorted out.
Regards . . . Andy
We had a power outage, and when the power resumed, I got the U81 message. I switched the unit off and on, and I could use it again. I don't live in the UK. Any advice on whether this is likely to occur again?
Nice to see you again
Thanks for the kind words. All the best . . . Andy
Thanks for another great video.
Thank you for the comment, it's nice to know that folk are interested. Regards . . . Andy
Was the circuitry in this machine worked with the old lead solder or the newer lead free solder?
Thanks for the video, I've just ordered my repair kit from wizardfest on ebay.
Hello are you able to tell me what the part wth the copper cord wrapped around it is called?
Hello Andy.
I have the EZ45V model of Panasonic video cassettes recorder. I
bought it fairly used recently but it developed the same kind of fault yours had with the error
message, "U6I" and stopped working. The power comes on and that is all;
once it shows this error message, it stops there.
Please, do you have any solutions to this problems.
Do you know can you run S-vhs in and out of that unit as a pass through?
Iv ordered my kit :) just wondered.. how do you know which capacitor goes where? I can see on the circuit board it is identified.. but is there a corresponding number on the cap??
would you know if the RAM Drive/digital assy is available
Good tutorial Andy. I have a DMR-EZ48V, but the problem with mine is that the dvd drawer will not open. Any ideas on what may be causing this?
On your PCB some of those capacitors were fine, no need to replace them. A few were obviously domed but a few were just fine. Novices changing capacitors that do not need changing can do more harm.
Great detail Andy in your breakdown and advice. I've not long acquired a DMR EZ49V. It seems that Wizzardfest doesn't hold a kit for this particular model. I'm experiencing the same U81 error message so seems likely to be this common capacitor issue. Do you think the relevant capacitors needed would be the same as in the DMR EZ48V kit. Furthermore do you have any experience of the EZ49 ? I've got no knowledge of electronic components, but do have a good range of tools and a have a go attitude
hello mate, i have the same model but my tape won't go in, i have took the top off and found a little bit of plastic, but i can't see where if goes, do you know how to get the vhs mechanism out. i have nothing to compare it to.
Great video funny thing is my dad has just got the exact model from a car boot sale .the original owner had died and he got it for £3 as the remote was missing the vhs deck had someones wedding video in it and the dvd drive seemed like it was not working it had a film inside tried a couple of other disc a dvd and a cd read fine then noticed the dic from the drive was a blu-ray .Very helpful video as no doubt at some point the caps will also fail in the one my dad got .
Hey £3 that's not bad at all. originally one of the attractions of this particular model was that it can take RAM discs witch are reusable many time over. I use a hard drive now for most things, I love it as we record everything we want to watch and we never, ever, watch an advert! And yes I think there's a good chance your dads machine will develop the U80-U81 fault as it' seems to be a well known stock fault.All the best . . Andy
*I have a Panasonic DMR-EZ37V, the disc drive wont open and also wont read the disc! I found this problem after the drive couldn't read the disc, then wouldn't eject it! Any ideas whats wrong?*
Hi Andy, did the repair you carried out for Error U81 solve the problem, because I did the same repair and U81 is still showing. Regards, John
AndyDaviesByTheSea I have the same fault but even with this video was not able to fix it. Any recommendations?
Received my capacitors from ebay yesterday. Here goes . ill let you know how i get on
Finally got to make a start. I have the circuit board out. Now to change the capacitors.
Taking my time. Finally soldered the 9 capacitors in the circuit board. Be careful flipping the circuit board over each time you look for where the capacitor is located. Its very easy to bend the other capacitors and the side wire clips, when lightly pressing on the board. Also when soldering. Now to put it all back together. Lets see how it goes
After checking it over and putting it back together. I plugged it all in, and success. It all works. Thankyou for a great video. I'm really pleased it went smoothly.
Regards Rob. From Australia
is it normal for the fan of these things to just go on for a minute occasionally while it's turned off..mine does that , seems weird, it works fine otherwise
It's been a long time Andy. Hope you're doing well!
Hi not sure if I replied or not but thanks for the thoughts, Yep I'm doing just fine thank you and I hope that all's well with you. Kind Regards . . . Andy
Hi Andy I own a dmr-ez48v from panasonic and after 2 years sitting in my attic now when I try to use it I have a standard message "please wait" looping and I'm not able to use it in any way.Do you think I can do the same fix as you did in this video to solve the problem or there might be something else?Thanks and good luck with your videos they are very good and explicit.
Got one the same it seems it's a regulator on the PSU that has failed with mine
I have same one but I can't shut it down and cd keep saying no disc and I can't open the cd tray if you can fix it for me I pay you thank you
Does this video apply to 240 V for Australia
Also can you use the unit without a remote?
Life Sized you can use some minor functions without the remote with the front buttons
you should just do story reading videos. The ASMR crowd would love it.
Andy I think you I am the same vintage i can remember the old type resistors and caps also sadly these day we live in a throw away time,I recently was at our local tip and found a Panasonic Hard Drive recorder with luck complete with remote,On the bench it worked fine I guess only about two year old,Thats is way thing goes these days Andy,Ian VK2IJ.
Scrap yards are treasure troves.73's . . . Andy
I have a DMR-EZ47VEBK. The VCR has an audio problem, it's all muffled!
How do I fix please?
Sorry can't really help you with this one but I'm sure that if you ask the question on the 'UK Vintage radio repair' site you'll get help. (they do cover TV as well as radio) Regards . . . Andy
I'm getting a issue with the dvd disk drive, it just doesn't seem to line up at all with the front panel and Jams itsself
I am sorry, I can't help you, but good luck.
Get onto the 'vintage radio and TV net' someone there is likely to have a solution. ( I know it's not vintage but these guys know it all)
Regards . . . Andy
This was an easy fault, capacitors in PSU but there is a fault when you replaced capacitors and the fault with U81 still appears...
Hi,great video.Can you tell how to fix the U61 problem on the Panasonic DMR EZ48V?
Hi sorry I can't help you but I'm sure that there is help out there for you. Good Luck.Regards. . . Andy
@@AndyDaviesByTheSea Ok thank you
Can you do a Video about PANASONIC DMR ES15 DVD Recorder..
can you please help i can not get a tape into my machine
I'm sorry but I can't help without actually seeing the machine.
Not as bad as I thought, 3 machines fixed
Hi andy long time , how are you getting on with hho , I found in the dark there is more activity as in nature
Hi Tony I haven't had any time looking at HHO as I've had a lot of things to keep me very busy but I have real hope that someone will find an economic answer to the conversion problem. I haven't go the answer but I bet when the solution is found everyone will be surprised at how simply it can be done, well, that's what I'm hoping for. All the best . . . Andy
Hello, I'm from Russia, I have a Panasonic DMR-ES 35 error code U61, how to repair, maybe you know how to do a general reset. Thank you.
Здравствуйте, я из России, у меня Panasonic DMR-ES 35 код ошибки U61, как отремонтировать, может знаете как сделать общий сброс, Спасибо.
wanted turn on it's says hello about six time come on channel 3 ,minutes den go off
Great video. I think of you often when I microwave something such as a mug of tea to re-heat it. A pet peeve of mine is that the microwave platter does not stop in the same position as it starts, I cannot see through the door as it is opaque so a manual switch off is impossible. What matter? Well, I put the mug in with the handle facing me and when the m/wave has finished after a minute or two the handle is usually around the back somewhere, so I go in carefully to turn the mug around to reach the handle. Every time this happens I think "I bet Andy could fettle this!" LOL. Why are these white goods so stupid these days when I can tell Alexa to control lights and heating etc? Regards.
Hi Will, don't get me started on modern equipment. I can't understand why we have to put up with so much rubbish software. When I used to design and built industrial equipment folks expected it to work tomorrow the same as it did yesterday, we don't get that with a lot of new stuff.Kind Regards . . . Andy

Heya, just to let you know, somebody seems to have reuploaded your video without credit, elsewhere on TH-cam -- they might be trying to make money off your content:
If you go to /watch?v=VKmxKQQ0xeA you'll see it's your video, you could probably file a copyright complaint there if you wanted it to be removed or you could speak to the channel owner
Hi thanks for letting me know, yes someone has simple copied the video and they are probable getting paid for adverts, anyway I've submitted a takedown request. Thank you for noticing the problem. I get a lot of fun out of TH-cam and it helps me a lot, in return I do things with the aim of helping other folks for free and without the bother of adverts for my viewers.Thanks again. Kind Regards . . . Andy
Just put Wizardfest in Google and got Harry Potter
you what you doing but your video make headache you moving your camera to much. but good info's
This was a waste did it work
some basic info but it would have been better if you had listed the capacitors that were used at the end of the video as you said you would @ 22:36. You showed the cap list during the repair but it wasn't really clear enough to read properly.Overall a laboured exercise with lots of ums and arrs as you fumbled your way through it like a rank amateur would have.
i have panasonic ez27 but i think. company invents worst players. programing. is in player is. bad only vhs has good technolgy because. Only vhs cassette is good tech nolgy
