SOURCE: red light on power button flashes, but no picture....blank screen

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

It sounds like the power supply board has some bad capacitors that need to be replaced. Samsung is covering the cost to repair this problem on some models. You can call 1-800-samsung to find out if your unit is covered.

Tv turns it self off after only 2-3 seconds and makes crack noise


Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.

Tv will not power up - makes a weird noise and red light blinks constantly.


It sounds like a bad lamp, a bad lamp driver or a combination of the two. Be aware that sometimes a bad lamp driver will blow a perfectly good lamp, so if you're not sure which is causing the problem, replacing BOTH would probably be the best course of action

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??


According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
