- Hi, this quick 'trying to fix' video shows my brother and I attempting to repair a Panasonic DVD player which will not power up. If you want the full length version then please watch • Trying to FIX: PANASON...
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince. - แนวปฏิบัติและการใช้ชีวิต
So glad I found your video, I had the issue with it just loosing power all of a sudden. I removed the case to get the disc out thinking the machine could not be saved. I checked the little fuse while in there and did notice a bulge and gunk on one cap. Not being an expert i just put the case back on. Later that evening i googled the issue with the EX77 and watched the vid. Sourced a replacement cap and followed your vid. Success for under £4 inc post 👍👍
Excellent. It is always good to see anything repaired rather than replaced, especially electronic stuff.
Have the same DVD player. DMR EX77. Just took my cover off. The same big capacitor is distorted and looks blown. Will attempt a repair. Thanks for sharing this info..
Love the quick versions!
I love when you make these quick versions! Double the dose! I find it quite difficult to find the time to edit my videos couldn't imagine make a quick and long version 😂 thanks mate all the best.

I always learn something from these videos!
Thank you. Your video helped me fix my machine and I have next to no electronics knowledge.
Either you have a twin or you have really good editing skills cause God damn you both sound very similar with headphones. I thought it was a voice over till I saw the hands
Amazing job ! Thanks for the video and hi from Ireland!
Thanks, I was over in Mayo a few weeks ago :-)
Another fantastic video 🤩
I would have changed all the caps to modern versions just as a safety point but really good job 👍
You are correct about those strategically weakened score marks on top of the capacitors. They allow a failing capacitor to gently open up and release pressure rather than exploding, which they would do otherwise.
Brilliant stuff..
I love you and your videos
Excellent!!! Your brother doesn't have much luck does he lol! He's providing a good supply of things to repair =D
Lol, very true...eBay's 3rd quarter profits will be hit hard without me buying up the junk :-)
LOL!!!
Hey Vince,good job,my friend gave me a Panasonic dvd player,he got a new one but gave me his old one to see if i wanted to fix it.i opened it and had a similar fault,3 capacitors though,i soldered some new ones in,it's working fine again now.
Excellent, I seen some of these on eBay with power issues. I bet it is quite a common fault with them :-)
@@Mymatevince I think it is a common fault with them.I might buy a couple and fix them too,then just donate them.
What type of ysoldering iron have you?
Great video fully explained could, you give the music track a credit. A fugue by Bach obviously but but which one cheers
where did you purchase the parts? do you have a link you can share?
Looking for some help/advice. My PVR records fine but when you want to record to dvd there appear to be a problem with the tray. It will come out but goes back in again. Sometimes it will wait but when i try to put a disc in it starts to close. If I do succeed then getting the disc out can be a problem. Don't want to scratch them. Has anyone had a similar problem and is it fixable?
Do you know how to open a pana dmr hwt230.they seem impossible to open..
2
faults here. Voltage on a capacitor does matter. A slight higher value is OK
But much greater than half again is not good
ESR meter reads by a high frequency low volt signal so Ecaps do not need to
be taken out to read. That is the value of the meter. You can protect the meter
with 2 diodes in parallel across the probes 1 east west the other west east.
Swollen caps are stuffed, they will leak and rot print
and Note Capacitors age due to high ripple current so PSU go long before
those in the other section
So when you install the new capacitors , you firstly solder them in then cut the excess wire ?
Yes, the excess wire will only cause problems. Just cut it so that it looks like the other ones on the circuit board.
Yes wow
Unfortunately the DMR-EX77 PVRs appear to eat capacitors for breakfast.
Mine has failed for the second time and needs several more capacitors replacing.
Often they fail under the Digital PCB VEP79157 and it's a right pain in the bum as you have to completely dismantle the entire unit to get the mainboard out... which I now have to do again 😞
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
#panasonic have very weak digital tuners...
