There are one or two capacitors in the power supply that open," leaving a slight puff at the top" in some cases.

This tends to be a power issue and monitor is hopefully under warranty and will need to be sent back. Otherwise it is pretty much done.

It sounds like you have a power supply problem and the safety shutdown has kicked in, the system will need to be checked by a computer tech with an estimate in mind.

The fuse is OK because if the main fuse is bad you will not get anything at all. It may have soldered in fuse in the backlight inverter circuits. You have to open it up and troubleshoot it down to component level. So please read my guide first if you are going to DIY repair.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Notes: look for bad caps first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You may have dying power supply due to bad DC filter caps, that will be the first place to look.

This isn't an easy solution, my friend. Go to this website and read what so many others are saying about the same problem. When you ger to this webpage, go to the link for the white screen problem, it's the same one you're having. http://en.kioskea.net/forum/affich-51640-laptop-screen-goes-white
I wish I could give you a simple solution, but there isn't one, sorry. These days it's usually cheaper to replace than fix, unless you get lucky.

Hi, by the time you source the parts and the schematics it will be cheaper to buy a new monitor or s complete pcb

I have used this supplier and found that they are ok

Hi,
The problem you have mentioned may not be due to contrast setting but the LCD itself . Power on the mointor and disconnect the signal cable from the back. if you see a self test box running on the LCD , the LCD is oK . If you donnot see the self test box the LCD is back. Dell doesnot service LCDs and you may need to get in touch with the local repair shop.

Try to install the OS once again.
If it turn up the same again then it may be the logical board problem.

BenQ FP92W LCD... | Answered on Apr 13, 2008


On your power board you will have a faulty surface mount fet with 8 legs that controls the backlights.
There are 4 of these, but if any of them fail the protection circuit turns them all off.
Best best is to get it to a local technician for repair. It is not an easy task unless you have the right equipment.
Hope that helps. =)
