Question about Dell Computers & Internet
As a laptop is involved, you may have bent a pin during connecting and disconnecting the monitor to the laptop. Check that out.
I assume you have tried cycling through the adjustment screens using the buttons on the monitor.
Before you try replacing hardware components, you might try "last good configuration" on your computer via F8 on start up.

i had same problem, fault was traced using a multimeter set to diode measurement, i found that one of the high power switch transistors in the inverter side of the power board was short circuit (there are four in the same area sticking up from the board, not surface mounted). normally they should measure 450 ish but when they read 0-010 its gone, pulled it out of circuit and remeasured it, gone, replaced and fixed.

Sounds as though the control unit has died. There are 3 parts to most monitors. The video processor board, power supply board and the HV/backlight board. You can replace the video processor board.
Make sure you leave the unit unplugged first and set for an hour. Usually no other fix then replace the board.

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.
