My compaq presario V500 laptop screen is black but laptop is working

Lcd screen inverter blown!

remove the battery from bottom, plug into ac power pack, and try it that way

compaq presario sr5030nx: This a Desktop? If so,Is the monitor plugged in, turned on, working, test with another machine, check the cabling from monitor to tower, unplug and inspect for bent pins. first. Now , when you say ,"compaq presario sr5030nx no video" and "black screen", do you mean your video player is not playing?

bad LCD.
costly fix
or bad GPU chip local. to LCD , but I think not.

1) put the laptop on a bed or a similar surface to close the air openings below
2) wait some time (15-30 min or 1hour) and let it get warm enough
3) restart.
it worked for mine. hope it works for you too.. the laptop seems stable and does not give any more beeps (for now).. good luck !

Hi,

Its not compatible. It has different screw listings then V4000.
If you could provide me the product No. which is at the bottom sticker of the notebook of your Compaq v4000 laptop then I can find the part no. for LCD screen which is less costlier and exchangeable.

When I opened my laptop this morning my computer won't come on. The screen is totally black. I took out the battery and put it back in ---- still nothing. I plugged it in with the power cord --- nothing! What is wrong with my HP Compaq Presario CQ60?

that is probably *********** board...me too same problem.

i have the exact same problem. try connecting the laptop to an external VGA screen. if it works, then the problem is most likely a loose cable (connector). It turns out that the connector (which connects the motherboard or gfx card to the LCD screen) on my laptop is torn and cut. see if u have the same problem. this link might help u check out ur problem:

Firstly you need to check if your laptop is bluetooth enable, if yes then you can activate it from control panal.
