Re: Panasonic viera th-l32c22m
Can you post better pictures of the power supply.
Have you checked the On/Off switch is working OK and what voltage if any do you have across the two legs of the large capacitor.
What voltage rating is given on that capacitor.Last edited by dick_barton; 06-28-2018, 03:40 AM.Willing to help but I'm no expert.

Re: Panasonic viera th-l32c22m
What is the P/N of that SMPS IC mounted on the heatsink in the hot side?
Since no PFC so he is probably getting around 330VDC.
There is small lytic startup/running cap in the hot that shoud be checked or just replaced it.
The rectifier diodes on the cold side all tested good?Last edited by budm; 06-29-2018, 09:08 PM.Never stop learning

The red-power-light Viera LCD TV, does sound like something pre-2012, if not pre-2011 or pre-2010. You can tell it's that period, if you see a mercury warning on the back. I have an October, 2010-built Viera TC-L42U22 that was given to me, the only problem, seems to be some image retention.
It looks like you haven't showed us the boards for the backlight. If it's CCFL-based, there will be inverter transformers and often little blue things, which I believe are KV caps for the CCFLs.
The LED-backlight versions, often look like they hardly have anything, LOL.Last edited by RJARRRPCGP; 06-30-2018, 03:30 AM.ASRock B550 PG Velocita
