Tricky!! oh hi im Dyanne.. a totally unresponsive black screen can be th result of failure of th LCD or LCD inverter.( a specialized piece of electronics that energize th screen) to rule out th failure of th video display adapter or circuitry, try plugging in an external monitor..a standard pc monitor.. attached direct to th lappy. if it works, (as i susopect) th motherboard and video display are both working ok and its th LCD which is at fault. this can sometimes be repaired by a competent specialist. good luck xx

Actually it boots, just that you don't see it. Try using another monitor - even a tv will do: disconnect the present monitor, connect the new one and reboot. If you get an image then the monitor is dead, replace it. If you don't then the onboard video card id dead, get a new one and try again. If even now it.s dead then you need a new motherboard.

Lcd lights got dimmer


First check to make sure the power adapter is connected to the laptop properly, if not it runs off the battery and the display is dimmer.
Second check the brightness setting, you can adjust the brightness by pressing the Fn key plus the F7 or F8 keys to adjust the brightness.

If this doesn't work then :-
The problem/fault could be one of several things. Could be the CCFL lamp, the inverter that supplies high voltage to the CCFL lamp or the video card.
The video card cannot be replaced on a laptop, it is part of the motherboard.
To determine if the video card is faulty, connect an external monitor to the external video port on the laptop, power up the monitor first and then the laptop. The video output will switch automatically to the external monitor, if you see a normal Windows image then the video card is OK.
Next, shut down the laptop, disconnect the monitor and power up the laptop. After the laptop boots up look at the LCD screen at a sharp angle and if you see a dim or dark image then the fault is a faulty CCFL lamp or inverter. Most likely the CCFL lamp is faulty, but the inverter is easier to replace.

Multiple lines on screen


Try connecting an external monitor to the your laptop and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

PC DO NOT BOOT


It seems that you don't have any Operating System installed. You need some bootable OS setup disk, and change BIOS settings to boot you PC from CD. Insert disk and restart PC, then follow onscreen instructions to setup OS.
