Question about Vizio M370NV 37 in. LCD TV
My TV will turn on by switch or by remote to the point of lighting the Vizio logo and the red laser/LED on the optical cable connection. However, the LED backlight for the panel does not turn on so I am not able to see anything on the screen. No sound either but can not tell if the TV is in a mode where there should be sound. Disconnecting AC power while the TV is on yields a flash from the LED backlight indicating the LEDs work and power can get to them. No visually obvious blown/leaking capacitors on the power supply board. System may have been victim of lightning strike through cable or AC. Thanks

Yes it does sound like the mainboard. But we have to confirm. I will see if there is a service manual for this unit in my collection but do you think you can safely work on it? Have you worked on electronics before? The last thing I want is you hurting yourself trying to fix it. HV circuits are not to be messed with unless you know about them.
