Re: Vizio M65-C1 No Picture, Backlight or Sound, External LED Working



Edit:
Actually it looks as though we have our connections crossed. CN9201/CN9203 ON/OFF and DIM is not used by the PSU, but it is used in CN9101/CN9102 which ends up going to the mainboard. Being late last night, I overlooked that....

Nah. No liquid cleaner was used. In fact, I am not sure if it had ever been dusted either. Good thing my cleanliness is not directly related to this item

If there is some further test I can do, I am open to suggestions....

Hi All From Texas,

I have searched the forums and believe I have a bad mainboard after testing my power supply and coming across this thread where the OP had low On/Off voltage on Pin 15 (+0.149V~+0.157V) of CN9101/02.

If someone does not mind looking over my results and reassuring me that this is indeed the case and the mainboard is bad, it would be much appreciated!!

Oh, Hi Everyone! Like, resistance is futile, I chant 'Ohm' in the shower every morning, and am the only one in my cooking class to catch a breadboard on fire.
