Replaced circuit board under warranty.

If the line is present in all inputs and modes, there is a problem with the LCD Panel. The only way to fix it is to replace the whole LCD Panel which is very expensive (usually around $1000+ for 40" Sony). Unless the TV in under warranty, it is usually around the same price for a new TV.

check to be sure your remote is sending IR signal, with a smart phone camera hold remote IR eye in front of camera and click any buttons on remote, you should see a light coming from IR eye. If no light emitting, remote needs to be replaced.

Check your cables first to see if they are causing it. Faulty cables can cause all sorts of problems. If that doesn't solve it it could either be that the colour settings are wrong, for example NTSC instead of PAL or vice versa. Sometimes it is something to do with copy protection. In some cases counterfeit discs, or faulty discs. And in some cases a fault on the DVD player.

Hi there...it is sounding like a backlight is going/has gone out...these can be proffesionally replacedat a repair shop...To self diagnose if it is the backlight take a flashlight and, with tv on and while on a tv channel and carefully form different angles look into the 'dark' part of the tv screen...if the/a backlight on a lcd tv/monitor goes out(even laptop screens) then u can still see a faint image with a flashlight(or without one with a good eye)....If you still see the (tv channel) image, then it is most likely a bad backlight......
I hope this helped you some, if it did(or not) please rate!...Thank you
