PICTURE AND AUDIO TURN OFF FOR ABOUT 45 -60 SECONDS AND THEN COME BACK ON. THIS HAPPENS REPEATEDLY BUT DURING THAT TIM THE GREEN LIGHT STAYS ON ALONG WITH THE FAN.


Dust has colected inside and fan is ot cooling the lamp adequately so there is a safety sensor to prevent overheating. Carefully remove the back panel and vacuum the dust out of the back and the fan. The better you clean the longer the problem will be fixed!

I have a KDF 42WE655..while watching tv, I heard a popping sound.


If the lamp is blowing that soon, the cooling fan is not working, or is plugged with dust. I have heard some people have a filter that needs changing or cleaning. Check your manual. The cooling fan is on the optical block and not easy to get to.
Probably a job for a tech.

I believe 4 blinks is fan error. You can take back off and watch fans in particular the fan for the lamp (this one goes out the most) The TV has a sensor so it knows if the fan turns.You can take a pencil and use it to spin fan sometimes that will jump start it (not a permanent fix just a test). You can try cleaning dust off fan and replugging the connector on the wires coming from fan.Might fix it if not fan will need replacement.

possible cause is the thermal fuse for the light bulb which is the back of the tv, next to the cooling fan.

Fan in the back


sounds like the bearings may be getting bad. That can ccause the same operating to become more noticeable. if it starts to make a growling noise you will need to replace it to prevent any internal damage to the chassis. This will also likely result in premature lamp failure. I would order a replacement fan.
