Question about BenQ FP731 17" LCD Monitor
I have the same problem as described in this topic just with a different BenQ model FP767. Do you think it would be the same solution? I have taken it apart and found all four transistors but I don't know how to check if they are shorted. Can you help please?
Use a multimeter and follow this =) The dots will be the pins (just for reference)
Set the multimeter to continuity mode. (gives a tone when the 2 probes are touched together)
Put a probe onto one of the outside pins and use that as a reference to being pin 1, then put the other probe to pin 2
The move the probe on pin 1 to pin 3.
so if you touch them like this:
1 & 2
1 & 3
2 & 3
If any of those give a solid tone, then it is shorted. But you will notice there are 2 of these at the top of the board, and 2 at the bottom. If one of either is shorted, then they both need to be replaced.
If you follow that you will soon see if anything there is shorted. The biggest problem is this is only the beginning.
Hope it helps =)
