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.

Remove the rear cover and check the lamp cover switch. Earlier versions used a black plastic switch holder that may break due to improper assembly. The part number for the holder is BP61-01240A. Newer versions use a metal tab attached to the engine. In this case, improper assembly may cause the lamp cover switch to be extended past its range, either breaking the switch or causing it to have an open contact. Replace the switch with BP91-01231A.
Note that in these models, when reinstalling the rear cover, it is best to remove the lamp cover first, install the rear cover, then install the lamp cover. This will make sure that the lamp switch is properly engaged.

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

SOURCE: Samsung HLP5085W DLP - lamp
Strange colors and flickering picture symptom shows problem with color wheel and/or dmd board.
Lamp is only light source in dlp tv and it has nothing with colors or picture flicker.
TV goes to protection mode because of some internal problem as mentioned above.
If you wish to repair tv by yourself then you should have service manual copy in hand and that can be downloaded from HERE for small fee.
Hope these info will help you.
