No picture (fan& bulb do not come on) but there is sound

I would have the power supply checked for the screen and then have the power button checked it may be faulty.

Try cleaning the little fans that keep the bulb cool, the temp sensor will shut it off so not to damage the bulb , the winning sound may be the fan going bad or not working like it should.

Your fan or thermal sensor may be bad..when that happens the tv will shut off to keep the bulb from overheating.

Yes,the problem is the colors wheel it dead.That one of the cause by the colors wheel,other are alots of squiling noises and making very loud buzzing sound.The cooling fan that u think is overheating,does it stop sometimes,when the tv is still on?Yes,than replaced it also,no than it still ok.Just hire the tv repairman,the parts he'll take care of it,don't order the parts,u might get the wrong parts or different sizes,that will not fit in ur tv.

did you try the Ballast

color wheel

i think its the fan that needs to be replaced. or it could be the bulb.

Try to open the bulb assembly unit and take out the bulb and put it back in. If you have an extra bulb, replace it and see if works. This worked for me. The bulb i bought wasnt compatible

sounds like the color wheel has gone bad..the part is not very expensive but it takes some work to replace it

Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

If you look in the back of your tv, you should be able to see the light from the bulb, if the bulb isn't working no light.
