Sony KDL55W800C Stuck On Sony Logo


Novice Member

I have a Sony KDL55W800C which suddenly started showing horizontal lines moving up and down the screen. Initially, it would return to normal after a while but then it stayed for a few days.

So to troubleshoot, I tried to do a factory reset through the menu - but after I started it, it didn't complete and was stuck on a black screen for a long time.

Now when I try to boot the TV, it just shows the Sony logo and doesn't start the Android OS.
I tried the hard reset through the manual buttons (by pressing power + volume down and then plugging in the TV) - the TV turns on, shows the Sony logo and the light does turn green - but then it reboots and then just shows the Sony logo and goes black again.

Any help on troubleshooting and getting the TV back to regular working condition would be greatly appreciated.

Thank you!

The TV worked again after replacing the board - but the lines going up are still an issue - any advice on this?
