Most require the set to be repaired. That's a known solution so my guess is your words "no solutions" is code for DIY free fixes. There's a second problem in that there are rarely any user serviceable parts. So we're back to a repair tech.
I have seen many posts on this but no solutions. I have a 3 yr old TV with intermittent vertical red lines. Sometimes 1, 2 or 3 and happens with any media and and all inputs (aka multiple different cables, from cable, laptop etc) . Any solutions ?
