Last night my screen started to flicker... it will dim a little, horizontal lines appear and shift downwards then normal, and repeats every 2sec.

I unplugged the TV, held the power for 15sec, and left it unplugged overnight but same issue.

Not an HDMI cable issue, it only has the one plugged in and unplugged and at the ROKU main screen the issue still persists.

It's a TCL 55R615 55" TV.

Any ideas? Only thing I can think of is to remove the back and clean connectors.
