Is the cable connected securely to the monitor?

Dear Technician:

I found you on the Internet. I'm living in Puerto Peñasco (Rocky Point), Sonora, Mexico, 225 miles miles south of Phoenix.

Have an HP ZT-1170 Presario notebook, purchased new in February 2002. The 15' LCD display module suddenly went black, NOT as a result of toggling display options (Fn-F5). Brightness adjustment has no affect. A hard reset didn't cure the problem. The unit works well with an external monitor, so that appears to eliminate video problems. In a darkened room, I can see very faint images on the LCD screen, so the video signal is present there, and the unit is not in Standby mode. Could this be a back light problem and how would one go about fixing it if it is.

Do you have any other ideas as to what my problem would be?

HP's part number for a new module is F3379-60970 (for $1,204), and for a refurbished exhange is F3379-69070 (for $814). I don't think I need a module, and even if I do, I'm not willing to pay those prices.

Data - Product # (1P) F3380H IB / Serial # TW20708984 / OS WinXP Home / BIOS Insyde Software IB.M1.04 / Video S3 Graphics Twister @ PCI bus 1, device 0, function 0

Based on the info I've given you, is there anything that I could do that could remedy this problem. Thank you for your time and any help.

Check the contrast adjustment,if there is no change leave it at a middle setting Check brightness adjustment, if there is no change leave it in the middle settings Check the cable that detaches the monitor-to-computer, exchange it for a good one.

check the fuse in the monitor If one is present, it should be visible from the back of the monitor.

Look for a black knob that you can remove Check the fuse for a broken wire indicating a bad fuse Check the air vents if are clear of dust or other obstructions.

Check for a switch on the back of the monitor for choosing between 100 volts and 220 volts.

Check if the switch is in the correct position If none of this things work take the computer at the service center.
