My monitor boots up with computer, but turns black when it gets to the desktop. if i turn the monitor off, then on again, it stays on for 2 seconds then turns black. can someone help me?

The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro lamp that provides the back lighting for the screen.

please check the signal cable..... sometimes the signal cable gets faulty and it would be best if you replace it..

reinstall windows ur screen resolution is not accepted by monitor

you need new vga monitor card on differeny port i had same problem on my computer i was fixing

i think it can be the capacitor problem, open monitor an look for swollen capacitors. if you will find them swollen or mso 9]> Normal 0 false false false MicrosoftInternetExplorer4 mso 9]> mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:IT;} @page Section1 {size:8.5in 11.0in; margin:56.7pt 42.5pt 56.7pt 85.05pt; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> mso 10]> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} loosing the electrolyte, signs of burn, change them

oboy, One thing to try is the flashlight test. and get backto me with your findings. Tell me, does this lcd show a nice display only for 1-2 seconds and then a black screen when connected to a fully booted PC with Windows desktop displayed? Shine a bright flashlight 1-2 inches from panel and tell me if you see the WINDOWS START Button at lower left of screen even though screen is black! Get back to me if you can. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

i think this is the problem of your monitor eht get it repaired

most common lcd monitor break down, check all electrolytic capacitors for leakage and loose board solder specially on the ccfl inverter section.

Well the first and second paragraphs make me say the Inverter/power board must be replaced.

A white display typically means either your display cable (in your monitor) is loose or logic board is dead.

Either one of these things typically mean take it in for an estimate to repair, and if it's too much, buy a new one.
With your luck I think I might switch to big cheap CRT.

Check the cable connections on the back of the monitor and the PC it sounds like the connection isn't made properly make sure they are tight.
