Vizio TV No Image Black Blank Screen No Backlights Basic LED... Led drivers are on the power supply board. Here's a video

Posted on Sep 09, 2016

  • selzlerj Sep 09, 2016

    The guy in the video says" as you can see here it's on the power supply board". That doesn't help me because I don't see it on the board I'm not sure where exactly it is. There's no markings or notations on my board to tell me. I'd like to test it but really have no idea how. Additionally, when I chatted with the people at ShopJimmy.com they told me the led driver was on the main board for my particular tv. This is why I need someone to point out EXACTLY where the LED driver is.

    If Shop Jimmy told you your model TV has the led driver integrated into the main board, then that's where it is. You'll have to locate the wire harness going to the leds and trace it back to the board connector on the ain board in order to test for voltages.

SOURCE: I have a Vizio E500i-b1 50" led tv and if I turn it off I can not get it to turn back on for hours/days....any help is appreciated!

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. Surf the site with patience. Pull up older posts.

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.

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 E500i-B1 TV sometimes black screen with no back lights but has sound. Watched Youtube - may be Power Supply board. LED inverter must be on it. What do you think? Any other way to test it?

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.
