Check the STP7NC70Z MOSFET, it often shortcuts after about a year or two.
I'd thank you, if you shall please tell me the value of the R602 Resistor, it's near the mosfet STP7ZC70Z.

BenQ LCDs are known for poor solder connections causing the inverter driver transistors to short.
Result is no backlight.

unplug from pc, turn on monitor. if there is a 'no signal' or any image displayed on the screen then the problem is not the monitor..

BenQ fp737 monitor


Disconnect the signal cable from CPU and power on.You should get a BenQ Blue screen.
If no Display,Problem is definitely monitor related ie monitor has a hardware defect most probably the power/invertor board has a few blown components.
If you are technically able,you can dismantle monitor and check components on the Invertor board which you may find on my other posts.
Please reply if you need more help.Please rate this solution.

Try to plug into another computer and wait to see.
If it turn up to be same it somewhere defect from the main board of the lcd.
If if not the same turn up to be, you should reinstall the OS because the software is corrupted or your display card problem.

Secondary monitor


When you first switch on Does it show Benq?If not the inverter circuit has failed.If you are technically able you can try resoldering transistors on inverter board.If your display is black all of the time transistors could have failed as also related fuse etc.
And yes please check with BenQ Normally these have a 3 year warranty.
