Re: Vizio M421VT LED no display

We have two M421VT tv's that have no back light, but have video. On one the Vizio led blinks 96 times before it stops and the other blinks 36 times before it stops. After each one stops blinking we can press power and get video, but no backlight. We have voltages on the connectors similar to what you reported.

Are you reporting that the problem on yours was solved by replacing just the power supply? Can you tell me the part number on the supply?
