Re: Vizio D55-F2 backlights won't turn on

Thank you Neil for pointing me in the right direction. I had ordered a main board off of ebay, installed it and no luck. Not being convinced the ebay board was good, I ordered a different main board, installed it and have a working tv again! The in-laws are very happy to have their tv again.

Hello all! I'm looking for some help in trying to fix my parents-in-law's Vizio D55-F2 tv. The tv will power on, but the backlights won't turn on. I can see a picture using a flashlight and the tv responds to the remote. The audio also works. I have tested all the LED strips and all of the LED's illuminate on every strip when powered from a separate source. I used a multimeter to take voltages from connector CN801 on the power supply board and had the following readings:

TV plugged in, powered off
Pin1-0
Pin2-0
Pin3-0
Pin4-0
Pin5-0
Pin6-0...

Re: Sharp LC-60EQ10U 3 long blinks, 1 short blink

Whew! The tv is fixed. I peeled off the tabs on the right side of the tv. I started with the tab on the bottom that appeared scorched. The display was much better in the area where I had removed the tab, but was still poor higher up on the display. I removed the other 4 tabs and the screen looks great. I found some great information in a few other threads.

Hello, I'm looking for some help on fixing my parents-in-law's tv. The tv is a Sharp LC-60EQ10U. They said that the display had dark horizontal bars that were spaced a few inches apart (I don't have pictures of this display issue). The tv would not respond to the remote or tv power buttons and was eventually shut off by pulling the power cord. The tv display would not turn on and an error flashing code started on the front of the tv with 3 long flashes and 1 short flash.

So far I've tried replacing the main board and a t-con board purchased off of ebay with no change in the tv....

Re: New Members - please post your introductions here

Hello everyone! I have enjoyed reading through the great information on this forum and have already found answers to many tv problems so far. I don't have much knowledge on electronics yet...just enough to make me think I can fix things that turn out to be over my head
