Question.
Did you plug something into HDMI, USB or some other inviting hole? Like PlayStation, computer, usb stick? These things sometimes resolve by themselves, or just need a good kick.
Talking aboit cr@p, my $hitty Daikin leaked onto the wall mounted TV. The picture looked like hand drawn VHS copy. People on this forum were telling me I was fkd and the whole circuit board needs replacing, but I let it sit for a week and picture is 100% back to normal.
