U turn tv on hear any squiling,grinding or motor noises?Picture show up before it shut down picture have flashes of black&white within the picture?Yes,to all of these,this tv have a colors wheel and it dead,require the colors wheel replacing.No,none of these problems.The tv projection lamp,if in this tv like a 1 1/2 or 2 years,tv ben on an watches like 4 or 5 hours a day?The "LAMP" LED light indication lite up or flahes,the projection lamp life is over.Require a new projection lamp.
make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast. Call a local tv repair shop to further diagnose the problem.
These models usually suffer from a bad color wheel. You will know that the color wheel is at fault if the sounds goes away right when the lamp shuts off. Look at the back of the set and watch for the lamp to shut down. The color wheel is not a consumer replaceable item.
Look at the fan and verify its comming from the fan and not the power supply unit, you can clean the fan or replace it, but yes the fan would be likly the problem. Make sure you double check the power supply unit and clean if its needed,
when turning on the set will go three startup cycles about 2-3 min. then all three leds will blink/ possible causes /lamp/ballast/dmd board check or purchase the dmd board last (costs) also listen for arcing from the ballest at startup and fan noise if you can and color wheel noise also.if you hear the ballast arcing and trying to fire the lamp look at the lamp.
Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set
