TV Panasonic TH-50PZ85U 2 blinks

Re: TV Panasonic TH-50PZ85U 2 blinks

I have Vizio VP504 with this PSU. It doesn't throw a blink code. When you plug it in, the amber VIZIO led lights up (it may dim somewhat after lighting up) and that's it. No reaction to button presses or anything. I've read on AVS that this vizio was fixed by swapping the cap (do I really need to swap the IC too?) on the MC301 and MC201 board.
I'm going to order up the stuff and do it to see.

Kinkose, did you ever find out what you needed to about that resistor? Is that something I can do for you with a regular DMM? Let me know. Thanks

It's advisable to swap out the IC, but I didn't in one my Panasonics; it's been running for almost three years without issues. I swapped out the ICs in my other Panasonic. The ICs are inexpensive.

Did anybody ever answer kinkose? I did the same thing to my mc201.

I've sold mine, so I can't personally help you. Try contacting eBay seller Koshevo (his name is Sen). He rebuilds these power supplies and may be able to help you as he probably has a few cores on hand.

Thanks guy's i run across this forum before buy the Panasonic 50 for $60.
Well with a little dig throw out audio motherboards I got for free.

I found two 1uf 50v cap so desolder them and solder them on the m301 and mc201 the tv works good.

Only question is how I get the files to update the firmware on the Plasma?

I don't think that it's necessary for this model, only the older PZ70 series TVs.

Okay and thanks.
I'm glad to found this forum. I'm use to fixing motherboards with blown cap's. I'm not use to fixing flat screen tv's its fun to work on. I bought vizio 42 lcd messed up picture for 20 googled it here well followed replacing u33 $2 chip works amazing. Now 60 dallors for a TV Panasonic TH-50PZ85U cap's I had $0. Time to sell the 42" vizio :-)

I have all the guts out of one of these besides the lower buffers. All working 100%. Might be persuaded to sell/trade for parts I need!
