SOURCE: Monitor keeps going dark

It sounds like a LCD backlight problem. Bring it to an authorized repair shop.

A125 monitor is dark


If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp.

Hp laptop screen black at startup


Hi
I assume the fan is whirring and you have some lights/LED's glowing. If you look around the sides and back of the laptop you will see a blue VGA socket. Plug a spare monitor into this blue socket, philswift.jpg You may need to use a friends monitor to test it out. If it still does not show an image on the monitor, make the laptop change where it is sending the picture. To do this press 'fn' (function) and hold down. Then press one of the 'F' keys that has a picture of monitors on it. In the photo it is 'F4' philswift_0.jpg
Keep pressing 'F4' whilst still holding down 'fn' as this may scroll through many monitor options. Leave 5 seconds between each press to let the action happen. If you still do not get an image then the laptop monitor graphics card has failed. If you do get an image on the spare monitor but not on the laptop screen then you have a failed backlight or inverter. Angle the laptop and catch the light and see if there is a very feint image on the monitor. It looks very dark but you should be able to pick out what you would normally see. If you can see this very dark image it is the backlight. If you cannot it is the inverter or the LCD screen itself. From here on we are into professional level fault finding, you can see here http://www.daileyint.com/hmdpc/lcd.htm . If the laptop was old and slow it may not be worth repairing. If you do wish to go ahead and reapir send it off to a fixed price repair shop like http://www.sefton-computer-repairs.co.uk/screens.htm or myself at www.tecorum.com It takes a few days to repair and send back.
All the best, Phil

HP F1703 Screen goes black within seconds of startup


That is either the backlight or its power supply.

This is a bit tricky as you can get it fixed under warrenty but they will likely ask you to send back the entire computer not just the monitor. It is also something that you could fix or several shops could but the repair cost really isn't much less than a new monitor. You are not stuck using an HP monitor so anything will work and you can get quite a lot bigger or better for about $120 and up. Repair cost is going to be $80-$100 so as you can see for just a few dollars more you have a new warrentied monitor.

The monitor screen lights up, then goes dark.


I assume that you get the same symptom when you hook this up to another PC. You will need to open it up and check the fuse, solder connections, etc. Please see pictures here for guide: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

My power comes on my laptop but screen is dark


First, Plug in an external monitor.
Press <FN> <F4> to toggle between lcd and external monitor to see if it will light an external display.

if that does not work...check your numbers on the bottom against this list. HP knows of flaws on the DV6000X. I loaned a friend a laptop so he could send his in for repair. If the number matches your laptop you are eligible for free repair.

Hp laptop wont restart


please connect your laptop to external monitor.
if it works with external monitor, then the problem is with your laptop monitor driver.if that is the case, then re-install laptop monitor drivers.
if it doesn't work even with the external monitor, then re-install graphic card drivers.
