no power no standby light
I have a Vizio e470va I tried turning the tv on with the power button and on the remote and in both instances the outcome is the same. The tv does not power on and there is no illumination on the Vizio logo. I removed the back cover of the tv and tested the voltage on both 5v pins when the mainboard is connected. I am only reading 3.5 volts on both of the 5-volt pins. When I remove the mainboard from the equation and retest the 5-volt pins I get a constant 5 volts on both pins on the PSU. mainboard p/n TQACB 5K05606.
Is dit een goede vraag?
