Question about Vizio Televison & Video

The backlight is out on my Vizio E500i-B1 LED TV. Can you help me locate the LED driver board? It is not a part of the main or power boards, the Tcon board is under the metal cover in pic. Thank you!

    I have already been to ShopJimmy.com and there is no video for the specific design tv I have. They also don't have a technical support staff which is why they sent me to fixya.

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.

Vizio 55" E55-C2 LED backlight issues. Was working fine until one day half of the screen's backlight stopped working and so half of the TV shows good and the other half is darker. Tcon or LED driver?

Vizio e500i b1 black screen, no image


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.

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.
