Open Question

Inverter DS-1107A damaged

The inverter DS-1107A of my BenQ fp937s+ is damaged. A new one is available for a 17" screen but not for the 19" inch which I have. Can you tell me where I can get a DS1107A inverter for a 19" Benq fp937s+.
Thanks for the reply.

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

The only solution I've been able to find for this is to turn off the computer for a minute or two and reboot, while rebooting, it is important to keep the mouse moving so the arrow on the screen moves. This should provide a temporary fix, I'm unsure about a permanent one.

Classic sign of bad inverter. Since it is inside the LCD not something you can fix yourself unless you work with electronics. Needs to go to the repair shop.

17" flat screen upper half is dark until "thumped"!


The inverter board that controls the lighting on the screen is dying. since its a 5 year old monitor and only a 17 inch. the cost to repair is greater than the cost of buying a new one. unless you know how to replace the part yourself. I think its best to just buy a new monitor

Check for blown MOSFET IRFU9024N and transistors C5707/5706, and fuse in the inverter circuits section. Also look for bad caps with bulging top/seal. See some pictures of failed Dell monitors (BenQ made alot of monitors for Dell), http://s807.photobucket.com/home/budm/allalbums
