Won't turn on

When the power is turned on by remote or power button a buzzing noise comes on and the led light for the timer stays lit. We can't turn it back off by remote or button we have to unplug.

Re: won't turn on

Only way I've found to fix (temporally) this is to unplug and plug the power plug into the wall socket...... sometimes it takes a few tries but it does work. I had a few tv techs come out and look at it. One wanted 400 bucks to fix it and told me he couldn't guarantee the work or the part if it had the same problem again. Hate to get rid of it I paid about a grand for it back in 2002/2003 and bought a home entertainment system with it

Set worked fine when turned off. Now nothing happens when pwr button is pressed. Timer light does not come on. If system reset button is pressed, pwr led flashes for 60 secs. System is still dead. Status...

If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.If you hear strange noises like buzzing or humming noises it could be the color wheel which is a little disc that has a gamma of colors and spins at high rpms.When the light of the lamp goes through it creates the colors on your tv.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on. For parts you can find them in or God bless.

I have a 56" samsung rear projection tv that won't turn on. the red standby light is lit and when i push the power i hear two clicks and the green timer light flashes quickly then the green led stays lit...

I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.

My RCA D52W20 will not stay on

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard

Picture went off still had sound then i turned off at panel now only red timer/standy stays lit sony 61" projection

First plug in again and look at led light, the amount it blinks tells what is wrong. Then if it stays lite it tells something also. You can try Display-channel 5-volume +- Power(service mode). Then Channel 8-enter(test reset). If this doesn't work then you will have to replace somethings like F601, R607, Q601, IC601, R612, VDR601.
