I recently repaired a similar model of this (owned by a shop). It had the same *_U81_* error and when I removed the top cover I found several ruptured capacitors on the power board. To save time, and reduce repair costs, I simply replaced the board with a good used working one pulled from an identical unit which had a faulty VCR and DVD drive. Once I reassembled the owner's unit and powered it up, after the normal "PLEASE WAIT" display it all worked perfectly; DVD and VCR. I then re-tuned all the DVB channels and set the clock. After some more tests, I returned the combo (now fixed) to the owners who were happy.
I like this guy because he is clearly very honest!!
Just got this exact model on freecycle with the same error code. Going to use this video as a guide! I’ve never changed capacitors before so fingers crossed! The deck came from a smoker’s house so it’s covered in tobacco stains 😢
Good luck with fixing it. It really is quite simple if you can solder.
Well done 👏 bringing another machine back to life
Thanks... Was still watching when I came to the "hope it's not a porn" comment.. Actually made me lol.. Also, yes, one of my fave films too... Surely you can't be serious!
Great minds 👍
Great and informative video as always thank you. I repaired quite a few Panasonic VHS recorders through the first lockdown all with similar capacitor faults using used caps doing the same as you with an ESR meter to check if they were good or not. The quality of new caps these days is debateable especially if you go through Ebay so I tend to use suppliers such as RS components or CPC. The larger sizes of electrolytic caps can be expensive so it makes sense to recycle and of course you dont have to wait for delivery. Thanks again 5*
Thank you. I usually use rs components, I've never had any problems with them.
good video as far as information regarding the error code U81. I would never bother doing the job twice though when once is more economical so just replace the caps at once since they are so cheap to buy anyway. I would also only use element 14 over RS components but have somewhere even better to go than both of them and have been going there for close to 40 yrs.
I've got the 48 model with the u81 error. For the sake of a few £ I'm gonna have a go myself. I'm going to take one out, put one in so I don't forget which goes where. Wish me luck and thanks for the upload.
Good luck mate and well done for having a go. 👍
Спасибо!
13:21 You: WHERE'S THAT TEA???
Your Wife: Huh? Yeah I know! I'm coming.
It was the wife not my mum lol
@@RetroElectronicRepair oh right FIX INCLUDED
Do you have a full list of the capacitors that you replaced and possibly a source that sells all of them? I have this exact model that I need to replace the same capacitors.
Sorry for the late reply. I don't have I full list as this was a while ago now, I think I did find a list online somewhere. When I buy components I usually get the from RS Components website, a reputable UK company. There are also cheap options of capacitor packs on amazon that have various values and about 50 -100 in a pack.
Which if any of these are critical values ? Can i replace the 120 micro farads with 150s for example
I'm not sure if they are critical. See what happens by using a 150 I don't think it will hurt it as most caps have a 10-20% tolerance anyway. I am only a novice though so don't take anything I say as gospel.
I just repaired my DMR-EZ47V by replacing some of the capacitors, but for some reason the sound doesn't work very well when playing from VHS tapes. I mean, you can sort of hear it, but it's quiet and fuzzy. If I play a DVD, the sound works perfectly. If I play the same VHS tape in another player, the sound works.
The capacitors I used to repair it I bought from Element14. I got Rubycon's with same capacitance values but higher voltage ratings than the originals.
Well done on getting it working. The sound from the VHS could be an alignment issue with the audio head or play head. The audio head is on the tape exit and there should be a black head and silver head. The silver one is the audio that has some adjustable screws on it. I wouldn't usually mess with these as you really need an oscilloscope to align them properly. If the picture is perfectly fine you could try and adjust the audio head very slightly to see if it improves the sound.
@@RetroElectronicRepair Well, I discovered that the audio works fine when using analogue output, but doesn't work properly through HDMI or when recording to DVD.
@@Knowbody42That sounds like something is wrong on the digital part of the board which I think would be very hard to track down.
I'm hoping you can help me. I have one of these players. When recording vhs to dvd I'm getting two audio playbacks. So an echo as they're slightly delayed. The recorded dvd is as it should be. But how do I get just the one audio playback while monitoring the recording process?
Hope you don't mind me asking.
Sorry I'm not sure of all the settings on this model or why you would be getting that problem.
I have one of these, but last week I had a rare VHS (that I was checking to see if it worked) get trapped inside - it tries to eject but seems to lift up too high and hits the VHS covering slot when it opens and then automatically re-inserts itself. Would extracting it simply involve taking the top off and taking the video out of the slot, or would it need more extensive work? Would doing it myself risk damaging the video? I would try and find someone with greater knowledge if so, as the video is very special. Thanks for any response you may have.
The best thing to do would be to take the top off and watch as the tape tries to eject. It could be getting stuck on the door and you may be able to guide it out. Otherwise hit the eject button and pull the power out just as it hits the top, this should release the tape from the mechanism and you could then pull the front of the machine off and guide the tape out carefully. Make sure you do not touch any electrical components with the top off and while it's plugged in, it could give you a fatal shock!
Update... Changed capacitors (9)and all booted up lovely.... But... My original problem is still there... Wasn't working through HDMI so I bought a second hand HDMI board. All I'm getting is 100s and 1000s type snow. Works through composite though. I've tried two hdmi leads and two TVs. It says "HDMI" in the video display .. Any ideas?
Sorry but no, I have no idea about that. It sounds like that machine has had a hard life. Sorry I can't be any help with that one.
@@RetroElectronicRepair Never mind, I only wanted it for playing my old region 1 dvds and old tapes which it does on composite now. Thanks.
Mucha suerte, solo eran los condensadores
I got this kit from you on ebay a couple of weeks ago, I`m only just getting round to doing it, problem is, I`ve removed 3x 16v 120uf caps, & just realised theres only 2 in the kit?
Hi, you've not bought the kit from my eBay store because I don't sell them. If the tops of the caps aren't blown and you have a multimeter you could test one of the caps you've taken out and if it tests ok just try using one of the old ones.
@@RetroElectronicRepair Oh, sorry! I saw a long youtube address on his instructions & decided to just type the model number & Capacitors, & you came up! I didnt think 2 people would be doing instructionals on here!
Is that a samsung D8000 TV 📺 you are using
Seen it better on another video looks like its a Panasonic you have
Got the Samsung one in the spare room but it has vertical lines on it now
Really good tv but think its going now
Thanks for that - very helpful and saved me hours of faultfinding. Went from the U81 error to things at least playing, but I have another error message 1A - have you come across this? It's not in the manual unfortunately - I have no video just colours, although the audio does come through. I did have to substitute some values however, because I couldn't get the 120 and 680uF, so subbed 100 and 1000 respectively. The latter may be an issue so I'll try to source the correct value, but stores don't seem to carry those values any more. Cheers Chris.
Hi there - pls ignore the above! All seems to be working now, and the 1A is just the analog tv channel. The video wasn't working on HDMI, so I tried the composite outputs, which worked fine. Then I tried HDMI again, and all seems to be working. No idea why or how. Anyway, thanks again for you vid. Chris
I was going to say I thought 1A was one of the AV channels. The HDMI port could just have been been a bit dirty.
@@RetroElectronicRepair Yes, and I'm embarassed about the 1A thing! Pays to just stop and think for a while before going into print. C.
Hi there I've got same dvd and coming up with same error code u81 do you repair these machines and how much for thank you
Hi, sorry but I don't offer a repair service. I do this more as a hobby than anything else.
@@RetroElectronicRepair ok no problem
Where do I get capacitors for Panasonic DMR-EZ47V
Search for rs components, that is where I buy my caps from although you would probably have to buy a pack of 5 or 10 each. Otherwise you could probably buy a kit off of eBay.
I HAVE A PANASONIC DMR BWT 800 RECORDER IT STARTED LOOSING PICTURE AND MAKING LOUD SCRATCHY TYPE NOISES WITH THE SCREEN ON THE TV LOOKING LIKE IT IS OUT OF TUNE LOTS OF DOTS AND NOISY . I TUNED IT OFF LEFT IT FOR A WHILE IT THEN STARTED WORKING CORRECTLY FOR A DAY THEN STARTED THE SAME STUFF ALL OVER AGAIN ..NOW ALL I GET IS A BLANK SCREEN WITH THE WORDS NO SIGNAL !!1 I TRIED IT ON ANOTHER TV WITH DIFFERENT HDMI CABLES ETC TO MAKE SURE IT WAS THE PLAYER WITH SAME RESULTS ... NO SIGNAL .. THERE IS NO OBVIOUS BURNT CAPS ON THE BOARD THAT I CAN SEE ... THERE IS ONLY ONE HDMI PORT COMING OUT OF THE RECORDER SO CAN'T TRY A DIFFERENT PORT WHAT DO YOU SUGGEST ! PLEASE
It could still be a capacitor, it's sounds like it by the way it's failed. They don't always bulge or give you a sign they are gone. You would need an ESR meter to properly test the caps.
@@RetroElectronicRepair i assume it would be the capacitors on the power board ?? or not ?
@@RetroElectronicRepair can you buy a new power board for these ? or where can you get it repaired ? what cost approximately please ?
Hi bud you can get a box full of different sized capacitor, l got a great solder sucker off Amazon if you want l will give you the details?
The Amazon ones are usually cheap China copies and not very reliable. As I'm selling this I'd rather use a quality and reliable brand from RS Components, CPC or Mouser. The Amazon box is ok for testing though but I usually get ones from old electronic boards that aren't repairable or not worth repair.
hi there was guy that sold Japanese capacitors on eBay
Ive recapped of these but the video side still isnt working , it doesnt respond when you put a tape in , no error codes , no life at all from the video side ?
Have you check power is getting over to the other board though the board connectors?
@@RetroElectronicRepair yeh i found a schematic and checked all the voltage rails and they were all there , the problem was me , before i recapped it and soldered a load of dry joints , it wasnt doing anything at all, no display , no lights , so after i got it running , i presumed the please wait message was an error because of the vcr side seemingly having no power , turns out i just wasnt waiting long enough (ive never worked on a vcr before ) , when it initiallised it worked fine , video side came to life
Oh yeah, that please wait can flash for a while before it decides to come to life. Good job getting working though.
@@RetroElectronicRepair thankyou very much, and thanks for the replies.
I should add that i was "getting round" the please wait message, and getting the the vcr to turn on by toggling the power switch at the outlet , but only the dvd side was working .( before i realised im an idiot and just wasnt waiting long enough haha)
What does the code f60 mean
I think f60 can also be caused by bad capacitors.
Hi do you answer questions?
Yes, I try to reply to all comments and try to answer any questions.
I think mine has this problem. What lemon
I opened it up tonight, and your correct. Im from Australia
I hope you can get it fixed now. Thanks for watching.
It boots! Sloooooooowly, but it boots.
I broke the clips 😎
Look at them SCART ports 😍🔌 we never got them in 🇺🇲🥲
They are the worst connectors ever! Glad they've died a death and not really used now.
@@RetroElectronicRepair The Australia/NZ version of this combo does not have SCART ports (thank goodness!).
