Hello, i have a BenQ 17 just out of warranty.When it started to fail it would come on and the intensity of the brightness would increase in about 2 seconds and then it would go black.
If I turned it on and off, sometimes it would stay on for a few minutes or even an hour. It would need a cool down period before it would run again. Now its totally black and wont work, but has green light power.
I have it apart. There are no obvious signs of heat and the caps look good. The transistors are not located on the small inverter board, but they are on the larger board.
Can anyone tell me what i should be looking for next and how can I test the lamp? Thanks Jeff

Please specify the model or mention the serial no.Normally No Display but Power means defective Invertor circuit generally due to failure of C5707 and related components.
