When I turn on my TV it tries to come on, then shuts off and tries to come on again. It does this three times and then the Timer Lamp/Stand By Temp lights flash. Eventually I can get it to come on. When I first try to turn it on I listened for the color wheel and I here a ticking sound like something is spinning and then when the TV finally does come on I hear a definite spinning sound but dont know if its the fan or color wheel. I replaced the lamp so I am pretty sure its not that. It was doing it before I replaced the lamp and hence, that is why I replaced the lamp. Does this sound more like a lamp ballast or color wheel issue? I am leaning towards ballast... Once it is on I have no issues. Sometimes when I turn it off it decides to turn itself back on which is also why I think its the ballast. If the color wheel had problems spinning I wouldnt think this would have anything to do with making it come back on once it had been running. Sounds more like a voltage issue.
