If you replace the inverter board, you need to check and see if it is getting the correct voltage going to the board, from the power supply. The voltage should be written on the connector on the inverter. It is coming from the power supply board. Make sure it is correct, if it is correct, than you probably have a bad panel, if it is not correct then you need to change the power supply.

I have a Vizio E550i-b2 55 LED TV. I have no LED backlight. When I hold a flashlight to the screen I can see the images and I have sound. I was going to replace the LED driver? Thoughts??


U are on the right track - problem is caused by the board that drives the backlighting - the inverter board.

If you can get the number for the board it may be available on the cheap on ebay.

Screen dark unable to adjust/ external screen works fine.there is a 1/2" x 6" board just below the screen w/ #41095 on it. that board is falling apart, i need a new one


There are plenty of the screen inverters on Ebay, just search by the computer model number, not the inverter part number. They should be about 20 bucks with shipping. That is why your screen is dark, the inverter takes power from your power inverter and converts the DC power to AC for the LCD backlight. Yours sounds like is failing or failed.
