It sounds like a surface mounted capacitor blew out. Examine the main board and see if you can see the failed part, if you do then replace that board.

SOURCE: My Vizio E500i-B1 won't turn on, replaced the power board, still won't turn on. 24V pins are only putting out 15V, PS-On is outting out .3V. What can I check next? Please help! Thanks!

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.

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.

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.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

My Vizio e500i-b1 LEDtv went out last night. How can i tell if it's the main board or the tcon board that isn't functioning?


I would verify the voltages on the power supply board first because an improper voltage to a circuit board may make that board look bad.
