Vizio M65-D0 turns off then on

hello, quick question. I have a vizio TV model number M65-D0, came into my shop as it would turn off and on, showing the logo, then turning off over and over again, did a diagnosis and it seems to be the power board, however, after waiting for the same model of the power board to arrive, plugging it in and putting the ground screws back in, it continues to do the same thing, has anyone encountered this before? and I’ve tried putting the original board in, that didn’t work. could I have a bad motherboard also? if youve seen thing please let me know how it got fixed? also Tv is out of warranty.

@savfix it is continuously turning off and on by itself?

@oldturkey03 Correct, I noticed that later after spending a few hours on it I had unplugged it and plugged it back into the wall, jumped on here and then I heard it click on and it started cycling on and off

@oldturkey03 unfortunately, the customer had stripped one of the screws for the legs so I am unable to currently get to the MotherBoard to get photos of it.

@savfix sounds like some IC on the main board which is giving signals to the power board to turn things on (very simplified). Post some pictures of your main board (both sides) so we can see what you see. 在已经存在的问题里加入图片

这个答案有帮助吗？

Hi @savfix ,

Wondering if it is a firmware problem?

Worth a try perhaps to see if it does detect the USB drive etc.

Just a thought
