Samsung HL-R4266w DLP. Been a great tv. Never replaced the bulb. Yesterday the screen went all blue. Got audio, just a blue screen. No strange humming or sounds. Lamp from the rear appears to be working. Unplugged everything and left off for a few minutes. Removed lamp cover, while on, and detection switch turned off the tv. Turned back on and working normal for now. Any thoughts? Almost went and spent $1000 for a new led. Guy at locks electronics store, I won't name, said it sounded like the "light engine.".

Appreciate any thoughts.

It sounds like a light engine problem, and to be more specific to a DMD board issue. This is caused mainly by overheating.
:arrow: You can prevent this to get worst by opening the lower back cover of TV and vacuum all the dust inside.
:arrow: We also recommend you to let the TV breath a little bit more by improving the inner ventilation.
:arrow: Do not have the TV near a wall and if you can have a fan pointing towards the air vents near the lamp will help you a lot.

Please let us know if this prevent from happening again. :mrgreen:
