Hi all, is there any TV engineers on here that could help me out?
I have a Panasonic TH-42PX80BA, and last night without warning i heard a click/pop sound and the tv went off.
The fuse in the 3 pin moulded plug had blown and when i replaced it it blew again.
I have done a search on the internet at a few suggestions are that something has gone on the PSU board.
Does anyone know where i could source another one from or have any other suggestions. Warranty has obviously expired?
Many thank`s for reading and taking the time to reply

Oh, I was going to recommend an engineer but I have no contacts your way.
PANASONIC TH-42PX80BA TV PSU POWER SUPPLY UNIT BOARD LSEP1260 LSJB1260-2 (VV13) | eBay
is the PSU PCB which if faulty is consistent with the status : dead blowing fuses.

Here is the problem, there is a small chance other damage has occurred to the rest of the TV.
If you are competent enough to replace said PCB then all you need is the price of the board and a bit of luck!

are you feeling lucky?

I am a bench engineer, specialise in electronic repair and will help you as much as possible if you have any more questions or if you want to take the plunge.

all the best

Feel quite confident replacing the PSU/PCB, i was just struggling to find a replacement, searched the web for ages. I seen some used ones on EBAY but was a bit concerned as to how long one of these would last

Again it's a risk buying used parts but your only option for a cost effective repair. The original Panasonic part will be too expensive if available and you will no nearer if the set has other issues. In my professional opinion the ebay PCB is your best option if you are going to proceed. I would say you have a 75% chance of a reliable outcome.

Had a similar problem with a TH-37PX80BA. I got the board repaired by GTV Watford for £130 incl. postage, VAT and 3 month guarantee. Did the swapping around myself and everything works fine now, so if you are comfortable changing the board out then go for it.

Sorry for the late update. I ended up getting a psu board from somebody off ebay, who was clearing his old stock. He had a brand new board and delivered it to me for £120 all in if i recall.
Fitted it and tv fired up as normal. Happy days again.
