OK. I know two things that are still working with the TV: the light bulb and sound :-). The problem is: when I turn on the TV, The power/standby light flashes 3 times before turns constant green. The screen would slowly turns on for a few seconds, then abruptly stops (both video and sound while the power/standby led still green. About 15 seconds later, it would turn on again for a few seconds and stops. There is no red light blinking. I know the bulb is fine. What else is the problem? Anyone has similar experience? Thank you for your advice
