Re: Vizio P50HDTV10A can't find bad board
I replaced the main board the ctrl board the ysus board and the power supply board. Good news is the TV works and has really good picture (for a 720p). Bad news is now the remote control doesn't work which is weird because it worked perfect before I fixed everything else. anyone know how to test a IR board, or do I need to reset the remote somehow after replacing most of the TV's insides? Any help would be greatly appreciated.

Re: Vizio P50HDTV10A can't find bad board
Further testing the connector from psb to main is P800
with it unplugged led's on the ctlr board d2-0ff d3,d4 and d5 on. when i test the p800 pins (ac-d 4.8 then 0.0 testing shuts down ps)(rl-on 0.0 testing shuts down ps)(5Vsb 4.9-5v)(DET 4.6v)(VS-ON 1.1v)(5V-D 5v)(GND 0.0). I have seen two threads with similar problems but they end without a solution being posted.
Thank you all for your helpLeave a comment:

Re: Vizio P50HDTV10A can't find bad board
There is no image on the screen if that is the "test patterns" you are asking for I have no way getting them. I can test for ohms , ac and dc voltages and for shorts. when the seven pin connector is plugged in I have no dc-v on the Vs or Va and nothing on psb or ysus fuses. the fuses all test good but no power to them. I don't mind replacing boards, but I would rather replace just the bad one and not the rest of them.[ATTACH]143562[/ATTACH]This is a pic of the seven pin connector that seems to short out everything.

Re: Vizio P50HDTV10A can't find bad board
I may be using the wrong terminology. when the set is on and without the seven pin connector plugged in the screen will have faint light all over.
It is definitely a plasma of that I am sure. What I don't know is which of the three boards is bad. I am guessing one of the has a short somewhere, but I don't know how to track it down.
Thanks for your help with thisLeave a comment:

Vizio P50HDTV10A can't find bad board
Hello All,
I am hoping someone can help me track down a problem with a vizio p50hdtv10a that won't turn on or off. The tv is always on I can only turn it off by using a powerstrip. I had the bad caps on the psb and the problem with the picture not staying on so I replaced the psb and the ysus boards but it still wont turn on or off. If I unplug the 7pin connector on the left side of the psb(see photos) the tv will power up, relays click on and i have a backlight, three led lights on one of the boards to the left and below the psb come on. If that connector is plugged in I get nothing but...Last edited by Badplasma; 10-22-2016, 12:06 PM. -

Hello All,
I am a do-it-yourself kind of guy. My current project is a P50hdtv10a that has been about to go out for years. Now that it's gone I am going to try and revive itLeave a comment:
