Re: Fix for Benq FP737s 17" (Q7T3)
Krankshaft thank you for the reply!
I'm sorry if I haven't posted yet but the guys i bought the 2SC5705 shipped me the SMD version, so I had to wait they restock through hole version and sent me again.
Well I replaced all the 5705's to be sure and the 3A fuse. The monitor worked for four days, I was so excited, then it faulted again.
This time the CCFLs stay on only for half a second then they turn off. In this half second you can see the BenQ logo fading.
Then the power led is still green but you can see nothing on the LCD, even with strong light pointed at it. Before repairing attempt I could see the picture with this solution.
It seems that 5705 failed again (but no blown fuse) or they are ok and something else is faulty.
What can I do? I could replace the small 945 and 733 transistor, but getting new mosfets or DQ10DPF could be too much expensive and not worthing the waste of time...
