Sony KDL55W800C Lines Across panel

[Hwciua4i]

Hi,

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.

I have now replaced the mainboard and the T-Con panel on the unit and the issue persists.

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

Thank you!

Horizontal lines are bad panels. However, if you have a tcon board, you may be able to repair it with the tape cutoff method.
