Re: VIZIO M70-C3 Power Supply?
I do get 5.1v at PS on when the power button is pressed and red led on main board comes on for a while then flashes about 16 times and shuts down

Re: VIZIO M70-C3 Power Supply?
I am not getting 12V to any of the T Con pins. I'm not sure if it's the Power supply or Main Board. Does the Power Supply receive a signal back to the Main board to power up T Con???...Leave a comment:

VIZIO M70-C3 Power Supply?
No Back Light, No Sound, No Video The board and red light on the CPU audio out tries to power about a minute. Not sure if it the power supply is the problem. Attached photos of voltages at Power Supply board when powered up and then turned on.
Any Suggestions Welcome.... -
