Question about Vizio Televison & Video

Disconnect all the circuit boards from the power supply board and test the voltages again. If the voltages are correct, connect the other boards one at a time to see if one is dropping the voltage on the power supply. If you find one that lowers the power supply voltages to what you read before, that may be the problem board.

Testimonial: "Sorry Knight changed board still doing same thing. I did notice the motherboard very hot, you think this could be it? Power supply maybe?"
SOURCE: Vizio LED TV model # e500i-b1. No sound picture. On light stays on. Not sure if it's the main board or the t-con board or another thing. Did the flashlight test and didn't see anything in the screen.
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.
