If all 3 leds blink, it can be the lamp, ballast (lamp driver), color wheel, or dmd board (all are engine parts = engine failur). its usually the lamp, but you can listen to troubleshoot. when it turns on, you will hear the fans come up (humm..airflow noise), then you will hear the colorwheel (high pitched squeel.. it will come up to speed) and then the ballast will fire up the lamp.. if the lamp doesn't fire, you will hear the spark gap fire (a 1 second buzz noise indicating bad lamp).. the gap will fire 3 times, they tv will then retry again and again until it shuts off and kicks out the error. this power up path will help you listen to find your problem. i can assist further.

Check the lamp contacts, eventually remove lamp and fit back in, chack that you did not burnt new lamp when mounting it in, you need a multimeter to test lamp.

When i turn the power on it looks like the tv is going to come on but the lamp lite (on display) blinks and then goes out. the screen takes a little bit of a glow but no picture. all display lamps go out...


The place you purchase the set from has to help you or guide you in the right direction so you get the set service, if they dont tell them you will bring the setback to them for a refund or exchange,the manufacture is the responsible one but stores also have something to do.
