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 E500i-B1 won't power on unless power is cycled. After unplugging/plugging it back in it will work but it may need the power cycled a couple of times to get the audio and remote to work reliably.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

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.

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.

My Vizio mod E500i-B1 heard a pop and no picture or sound. Would replace main board be possible fix?


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.

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.
