Want to fix my Vizio D55u-D1 TV. Anyone have experience?
Have had this Vizio for about 5 years. After 1 year it began freezing - the picture froze with the only solution being to hit the power button. It would then take a minute or two to restart. Figured since not happening sometimes for a week that we could get by.
Then we've just noticed flickering in the upper left portion of the screen - there's a band that gets dark going from the left side to the middle and another one above it near the top that's not as bad. The other freezing problem persists as well.

You have main board issues, the write protect circuitry has caused the EEPROM data to become corrupt. A new board will be very hard to find and expensive, I've attached a link below for a new EEPROM however it's not something most people can replace it takes some special equipment and a lot of solder skills because of the very small size and the pads are easy to lift. Another option is to send your board in for repair, look on ebay and you will see places that do it like Copell TV.
If the status light doesnt light at all the first thing to check is the power board.
If you dont have experience it can be a dangerous procedure, do it at your own risk, TVs keep charge even after unpluging them.
I would check the fuse right after the power inlet and go from there. In my experience about 1 in 10 LCDs have only a blown fuse from a power surge, however it is IMPORTANT to check the rest of the power supply board before testing with a new fuse (i normally use the oportuny to change bulged capacitors and check voltages), if the cause was something other than a power surge it could do a bigger damage and ruin the board.
Hello DD777, it would be good to send one or more pictures of the screen showing the failure that occurs, to be able to evaluate the possible failure and find a solution to the problem
I wait your answer

Hola DD777, seria bueno que env?es una o mas fotos de la pantalla mostrando la falla que se produce, para poder evaluar la posible falla y buscar una soluci?n al problema
Espero tu respuesta

Chances are you have a main board issue, you should have run some voltage tests before replacing the power board, its sad how many people order boards that aren't bad because they don't do the necessary testing prior to ordering boards.
I am having the exact same problems with mine.
