3 Red Flashes. Screen won't come on.

I have a Sony KDL-55W802A tv. Walked into the room the other day and the tv wouldn't turn on and the red light would repeatedly flash 3 times. I looked up the code and it said it was either a bad main logic board or the power board. I tested and replaced the power board to no avail. Can anyone please give me insight into this issue? I'm stumped!

I have a Sony KDL-50W800B 3d TV and I am still getting the 3 blinking lights even after I changed the main logic board and the LED driver board.

Mostly it is NAND error (bad chip and or corrupt file system), no communication.It is programmed.it is same as the hard drive for computer.it goes bad by time, unfortunately.

Hey.. its the cover that goes on where the bulb is. There is a little nub on the cover sticking out and when the cover is in place it pushes the switch in. My cover has gotten a little melted and tweaked so the nub doesn't push the switch in all the way. I took some masking tape and rolled it in a little ball just so it fits in the hole. Maybe the size of a bb . After I reinstalled the cover I turned the tv on and waaaaaalaaaa! Its working again. I then put the other cover on that covers all the buttons and stuff and called it a day. . Hope this helps u if u didnt already go buy a flat screen.

We did not know that our bulb door was not installed properly. After reading this post we adjusted that and the TV started working fine again. Thank you.
