Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

Won't turn on...

My TV shut itself down and now won't turn on. I hit the power button and you can hear the "coming on noises" and the timer light around the power button flashes but nothing happens. If you hit the button again it is like it turns off. You only get the "coming on noises" and flashes every other time you hit the power button. I called Samsung and they took me through the reset process but nothing worked. Please help.

It's possible that the convergence IC's may be bad in this set along with a few resistors. A TV repair shop should be able to fix the set for you.

Samsung HL-T6756 DLP TV Standby/temp light flashing and tv won't come on. I have replaced the lamp and the fan is working. Any suggestions?

Remove lamp and inspect the color wheel to see if missing pieces or shattered---it will also just before failing give a high pitched or fan like sound and if running too slow or not at all instant shutdown happens.

Its also possible if you bought a GENERIC bulb--and used original cartridge the new lamp is bad.

No picture no sound


Probably, the selftest fails while turning on. If this is the case, press input&menu buttons at the same time for 5 seconds, then the green led will start to blink. Let me know how many times the led blinks.

Pioneer sd532hd5/kuxc/ca powers down on its own

Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.
