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.

I am not sure about your model but i do know on some samsung dlps there is a dip switch that has to be changed if you have the backwards color after changing the color wheel.I hope this helps.

SOURCE: My RCA is screeching
To install the color wheel, turn off and unplug the tv, take off the lower back casing (17 star type screws), remove the lamp door, remove the lower back casing. Look just left of the lamp you will see 3 smaller star type screws near a small circuit board (which is on the color wheel), remove those screws unplug cable from color wheel, unplug other end of 2nd cable from tv circuit board (just to the upper left nearest to the color wheel.
All you have to do is install the color wheel, plug in both cables, put the back on and place the lamp door back in its position, the lamp door pushes in a lillte blue lever which allows the lamp bulb to light up.
I'm in the process of doing the same myself on my RCA same model. Where did you buy the color wheel from?

That most probably seems to be a future issue with your color wheel, it's starting to go out, you need to identify which one you have before you purchase one, there are two kinds, one with a gold bearing and another one with a silver bearing
