Hi, this ‘trying to fix’ video shows my brother and I attempting to repair a Panasonic DVD player which will not power up.
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. .

I have had a Panasonic DMR-BWT720 Blu-Ray recorder with 1 TB HDD since October 2012. In September 2019 the HDD broke down – I lost all recordings, and couldn't record any more. I took it to Panasonic repairers DK AVS, who did a good job in replacing the HDD with a new 1 TB one. All went well for almost 22 months, until last Friday, 2nd July 2021, when the HDD failed again, with all my recordings lost. What can I do ? Why do the HDDs not last ? (I have had a Panasonic DMR-BWT880 since September 2010 with no HDD problems, but it only had 500GB, hence my purchase of the – 720.) Any advice welcome.

I’ve had this exact unit sitting in a drawer not working. Also no power at all.
I have a DVD instruction video I need to watch and thought I’d open it up for something obvious. I’m not a tech guy in this respect but I have a similar pair of capacitors that have these visual tell tales. Thanks for the confidence it’s a cheap fix and hopefully another item not hitting the land fill. Cheers from 🇦🇺

Hi Vince – my panasonic dvd recorder does not work properly – the time function etc seems dead – do these machines have an internal battery to keep basic functions going when the power is off – if so can they be replaced – thanks

monkeyengine 09/08/2021 - 16:14

Mines the same model and just done exactly the same, no response from the remote control or buttons on the unit. Un-plugged it and plugged it back in, then it was completely dead. Hopefully I can get it up and running again so thank you.

William Barrett 09/08/2021 - 16:14

I nearly los it . i forgot you were with your brother. glanced at the screen and see 3 arms …freaky

Alan Westwood 09/08/2021 - 16:14

Huge thanks guys. Have same DVD recorder and same issue ie suddenly went dead. Followed your video, found same 2 caps blown and replaced them. Then the magic 'please wait' returned. My first time doing soldering on a pcb. It was a case of throwing away, or taking to a repair shop ($$$$), or spend $20 and have a go!! So glad I did.

Hello there! I have a Thomson recorder, and somehow it just stucked after turning it on. The display itself says hello, but no reaction from the machines buttons or from the remote control whatsoever. Any idea what shall I do? The only way to turn it off is to remove the power cord from the network, and that shuts it off. I digitalized so-so many VHS in the last few weeks, but this never happened before. There aren't any signal on the TV as well, so i'm kinda clueless. Thanks for reading this, and have a nice day!

Fred Shead 09/08/2021 - 16:14

Hi Vince i have a Panasonic DVD/HDD/VHS recorder cant remember the model, but when i turn it on the dvd goes in and out a couple of times and it comes up with ERRHDD which i assume is a hard drive fault, it could end up on the scrap heap its about 10 years old, it is multiregional cost me about £400 orignally…any ideas…Fred in Essex.

Paul Facer 09/08/2021 - 16:14

I have the exact same model with the exact same fault. The exact same faulty capacitors also. I replaced them as described in the video and it works! There's some stuff on the hard drive that I hadn't wanted to lose so thanks to you I haven't. Great video and thanks again!

thinlizzysupporter 09/08/2021 - 16:14

Hi Vince. I’m a relatively new subscriber to your channel and I can’t get enough of your great trying to fix it videos. This one has encouraged me to have a go at fixing my DRM-EX77 and I’m pleased to say it’s been a success and is now working perfectly. Have you ever tried fixing an old boombox ? That would be interesting. Keep up the great work 😊👍🏻

Olayiwola Temileyi 09/08/2021 - 16:14

Anyone, to help me with this? please!!!
please I want to change my Panasonic DMR – EH65 recorder language, but I don't know-how

bob rew 09/08/2021 - 16:14

Another notorious component failure on Panasonic DVD player / recorders, are the voltage regulators near the PSU's heat sink. So in future, be prepared to change that if the machine shows "Please wait" or an error code but won't come on…

Stardreams Video 09/08/2021 - 16:14

Great video Great info. Thanks

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 😞

Peter O Reilly 09/08/2021 - 16:14

Very good interesting video!

David Ellis 09/08/2021 - 16:14

Surely it would be easier just to replace the board save all the faffing about. Seems like unnecessary hard work.

DAVID GREGORY KERR 09/08/2021 - 16:14

We have a similar unit i.e. PANASONIC DMR-EH50 and ours is still working, total recap joy me thinks.

paulsenior33 09/08/2021 - 16:14

It makes you wonder when you go to the council tip to get rid of dead electrical items how many are there because of such a small fault as a blown capacitor

Thomas Richter 09/08/2021 - 16:14

Electrolytic capacitors are DC. Ceramic capacitors can be both. To know which part of the power supply uses AC vs DC you only need to understand where is the Bridge Rectifier. The bridge rectifier can be a single 4 pin component or can be an array of 4 diodes (full wave bridge rectifier), or 2 diodes (half wave bridge rectifier). Everything after the Bridge Rectifier is DC.

andrew roberts 09/08/2021 - 16:14

Brilliant. I have a Panasonic DMRES20debs which is completely dead! I checked internal and external fuses. Both OK. Looked closely at the power board and noticed some odd lookimg capacitors. Found this video which decribes and fixes exactly what I saw on my board! Thanks guys. I'll go ahead and try my hand at capcitor replacement now!

20 minutos para ver 2 condensadores reventados y cambiarlos que lento. igual dejó mi like sólo por otros vídeos que e visto

WWE Beggar 09/08/2021 - 16:14

there's a website called bitsbox in the uk where you can order single capacitors and a bunch of other components that you may need at a very cheap price
