BENQ FP731

[[email protected]]

Hello There
My BENQ FP731 is turning on video comes and goes off and stays
black. IF I turn of the power switch( on
the monitor) and turn on again it will it comeback for 30 seconds and
bad again. I opened up the whole thing
and I can see all the capacitors looks good. No leaks. Pretty much end
of the road. Any tips guys?

thanks
Sam.

You cannot see electricaly leaky capacitors by eye. Most of the time
it is the same for failed components.

Use the proper tools to properly test the capacitors. Replace the ones
that are out of specs. Start in the power supply area.

For involved problems, these monitors are normaly serviced at the
board level. From out experience, the manufacture will not sell boards
or service manuals to non contracted service reps for their products.
