friend maybe your LCD was broken or loose. try to pull gently if it return to normal image.

your convergence powert supply is not working-
replace the supply or repair it

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Good Day;
Suspect Convergence IC's STK4274, part Number 2003191. Replace all three IK04(red), IK05(green), IK06(blue).
Good Luck, big IRISH.

these set are bad about the blue tube messing up.. what happens is the convergence board witch generates alot of heat cooks the blue glycol.... basically growing algea in the blue tube... it is possible to remove the tube.. and remove glycol and clean the tube then replace and adjust..i have done a few here at the shop

i have found when samsangs convergence are out of range perfect focus will fail. if the are out of range a technician will try to adjust the set in service mode. store these values and then this will be the base for the perfect focus. If the set has a bad convergence cuircit then they have to be replaced.

A screen drive issue is at hand and will require the help of a shop to get it back up to snuff....accordianman
