Question about Dell E173FP 17" LCD Monitor
Sounds like the backlight is going out. The display itself is okay, but without the backlight you can't see it (or you may be able to see it very dimly if you look closely). This is usually due to the failure of parts called capacitors in the monitor's power supply, although it could also be due to the backlight lamp itself. Capacitors are a much more likely cause.
It is possible to repair this by replacing the affected parts, but if you will have to pay someone else to make the repair you may just want to replace the monitor. New 17-inch monitors are routinely under $100 now. If you or someone you know has some experience working with electronic soldering and replacing components, you might be able to find detailed information on the Web about which parts need to be changed.
