Found PF751 to be open.
Thnaks for the help people.

Hi, after changing the transistors, you got too check the four transformers legs for cold joints. If not the new trans: blow out again.
let me know.

I tested this camera for a client. I didn’t have the light running for more than 15 minutes. The battery lasted approximately 6 hours before recharging. The LCD, however, had a few dead pixels - never saw this before. Tried returning for exchange and had to put up quite a fight. Anyone else seen this? http://www.batteryfast.com

Spot on! I has a FP737s-D. Q758 had blown. On top it looked like a black texta mark, but on closer inspection that transistor had a mico hole where the plastic had blown out. Underneath, was a dry joint. Benq are nice, in that the shade of green was darker, indicating heat. As Both transistors are a pair, replaced both. Lightening strike did the damage.

Its a problem with the inverter. check the 4 transistors, C5707 near the connectors for the backlight. If none are defective, look for the PF751 FUSE. It sure to be busted.You can replace that with another 3A fuse. Remember, you should only replace the fuse if you are certain there are no busted transistors in the inverter board. Otherwise, you now have a refurbished Benq Monitor
