Re: Vizio VP322 - no power, blown resistor and fuse

Just checked all green resistors, most of them unsoldered because they didnt read right on board - all tested good. I guess, only option left is to order another YSYS, or there something else can be tested? I tested some caps too - they all OK.

Re: Vizio VP322 - no power, blown resistor and fuse

Had it running for couple hours to check power board - after it got warmed up really good, those grains almost disappeared - still slightly noticeable, but only if you know what you are looking for. With regular TV/Movie play I dont see it even if I try, but I can see few (VERY few, not as many like on cold screen) when HDMI square goes away on input change or when it plays white titles on black background but I need look very close to notice it.
I wonder if it helps to diagnose problem? Or confirms that YSYS should be replaced?

Re: Vizio VP322 - no power, blown resistor and fuse

I just got another YSYS board I bought and turned out there is problem with replacement board - when I turned TV on, amber standby light turned to white like when it's coming on, but nothing else. I looked more closely on board, and even if it was listed as EBR39731301 part and posted pics showed the same sticker - board they send is EBR43988401 and definitely not the one they described and posted pics of!
It looks identical to mine, but apparently something is wrong with software or board itself is bad? I will contact seller for explanation, but meanwhile, is there anything I can do to make replacement board useful?
Also, is there any dander to damage other parts with this board installed?
