    Turn on tv, power light blinks for a few seconds then nothing. The screen does power up but stays a grayish black. Occasionally pink stripes flash across the screen, but that is it. It sometimes turns on without any problem, but freezes and goes blank after a few seconds (20-30). Began having problems on 9-15-08

Ok so I had the "EXACT" same problem. I came here and read the posts. I ordered a new power supply and replaced it myself. It worked like a charm, and I know nothing about electronics. It was super easy. For anyone haveing this problem, just replace the powersupply. You don't need a TV repairman you just need to take the plastic back off your TV, and remove the second metal back and then remove the power supply and replace it with a new one. That's it.

Power light keeps blinking Red and TV will not turn on


Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.

No Picture - Lamp Indicator Blinking


This may be the main power supply, or the lamp supply. This is providing that the new lamp is okay.

The service tech will swap out the modules to service the set.

No picture-lg ru-52sz51d


Depending on what light is flashing it could be a few things. If the Lamp light (the middle one) is flashing that is problem with or around the lamp. That orange or amber light is an indication that the lamp is reaching the end of its life

If it is the Temperature light (the far right one) then the TV is shutting down because it is over heating and you need to check the cooling fan.

Green flashing light - no picture


If the green power light is blinking and you have no picture, then your light bulb has burned out and needs to be replaced. It is not a cheap bulb to replace. If the TV is less than 1 year old it should be covered by the warranty
