Sounds like you may need a new lamp according to my Samsung DLP manual for a HLR4667W.

"Why do I need to replace the lamp?
The lamp used in a DLP TV has a limited lifespan. For the best screen quality it needs to be
replaced periodically. After replacing the lamp, the screen quality will be bright and clear as new."

no there is no way, you have heated up the screen backing. only way is to remove the lcd screen and change it. as the screen its self is only 0.01 or 0.02mm at the most thick, you will probably smash the screen.

Most likely you have a faulty LCD panel tabs. This can be verified sometimes by turning set on and tapping or squeezing the top left side of the TV. The only true fix is to replace the panel. I've been told that Samsung may offer to replace the panel or give you a discount on a new TV. Samsung is know to have LCD panels with premature tab failure. So it may be worth while to contact Samsung and see what they can do for you. There are videos on youtube that show case the problems and show you how to patch the problem. just type in "LCD panel tab" in the youtube search box.

The LCD can be replace just bring it to the samsung service center to replace new LCD and back to normal images.

indicates a picture board or power supply problem
take it in for a proper diagnosis and quite if not under warranty

maryam_edesa, Unfortunatly once they the screen panel is damaged it cant be repaired. the only thing you can do is replace the screen panel but it would cost more than a new tv.
I would suggest you use it untill dies byitself.

You have damaged the LCD Display, the cost of those are close to the cost of a new set. One day the manufacturers will put a safety screen on the front like the older projection sets had to protect those screens. When I sell a lcd set I always recommend to the customer to have a piece of Plexiglas installed over the front, especially if it's for the kids room. Of coarse it's a DIY project.

Replace the video board, if you can find one. Letting it cool down will not help any.

Sounds like your LCD panel has gone bad.

If the unit is under warranty, take it to a Samsung repair shop. If it is not under warranty, go buy a new one. LCD panels are usually more expensive then buying a whole new monitor.
