My question is about the 72" version of the same TV Model HL72A650C1FXZA TV Serial: AMBF3CKQB01234B Version: OG01 Came into room while kids were watching TV, and the screen was frozen. Picture was clear. No sound. TV would not turn off by remote or front-pannel stand-by button. Had to pull the plug. Plugged in and re-started, and the TV screen would not come on. Standby light comes on, then disapears when power button is pressed. Lamp light flashes constantly. TV will still not turn off by remote or front button. Onboard ‘channel +/-’, ‘source’, ‘vol +/-’ buttons do nothing. Replaced the bulb with high quality one at the link below. TV has the same problems even with the new bulb, except that now when the TV turns on, the screen illuminates but stays a flat black/grey colour. I am asking for advise on a way to test what components need to be replaced, or a suggestion on order of components to investigate, as I have little experience with this type of TV. Can anyone help or suggest the next step, as the next components seem to be $200 and up, and I don;t want to spend that kind of money without some level of confidence that it will help solve the problem. Update 10/15/2016 Here is the lamp starting video. You hear the click, one ballast ’tick’, and the lamp lights up.
@actionman1 thank you for the video. That clarified the lamp questions as well as the ballast. In that case I’d go back to the black screen with the lamp on is usually caused by a bad DMD board. I’d start there.
