Sony KDL-55W807C horizontal lines/rollover/ghosting
crwdns2934249:0crwdne2934249:0:
The TV is from 2016.
A few months ago the problem started appearing more and more right after turning the TV on. Most of the time it stopped and stayed away when turning it off and on again, but now that trick doesn't work anymore.
It looks like horizontal lines/rollover/ghosting and is wavering, also in the left corner of the screen there is a bright spot on and off clearly visible on a dark screen when booting up for example:

I also hear electrical buzzing around the tcon board, it seems to be a few seconds louder every time the lines appear.
I already reconnected all of the ribbon cables, no change.
Could it be the tcon board or is it more something like the LCD driver or power supply?
