If you hear the hard drive spinning and you think Windows is working but you can't see an image then :-
You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Did it display any video at all with boot options or HP logo? Any POST test or beeps after you started the laptop?
Try removing the power ac adapter and battery. then only boot it up with just the AC adapter (no battery).
Good Luck, JAJ

Had trouble booting the computer over time. Sometimes power light would come on and nothing else. By unplugging, waiting 15sec it would power up. Over time this stopped working. Eventually power light...


Time to look for a new computer. That and take out your hard drive to copy your files over.

Sounds like motherboard problem. Probably not worth repair.

I've got an HP desktop with similar problems. It turned on one day just fine. The next day not. I don't even get the boot up screens. Disconnecting Hard Drive and CD/DVD components do not help. I should at least get some BIOS POST beeps and a Hard Drive Not Found or such. I do not. On occassion it will boot to a blank screen with white cursor in upper left. Most the time no screen at all. On rare occassion it comes right on and boots Windows. I guess it could be the power switch ... but I doubt that.

Hp pavillion hdmi output was working fine and not the tv is dark. It shows a picture when booting up but once booted, the tv goes blank. Can you offer any solutions?


I had the same problem. The first time I used the HDMI port, it showed up perfectly on my TV.

But, next day I get a blank screen. When I rebooted the laptop it would show the windows splash screen and go blank.

I won't tell you how many things I tried that didn't work.

What you have to do is stupidly simple. Right click on the ATI logo in the systray, and then left click on catalyst control center. Run the basic wizard. I'm not sure which screen it is on but choose "clone". Suddenly, a miracle happens, and it works.

I don't know what kind of genius decided to make a second display not work at all unless you ran a wizard. But thats what I did to fix it.

Acer Aspire 5052 nothing on LCD


If the LCD display worked until the processor over heated and then went blank, and would work again once it cooled down, then yes I do. As you described above, the screen going blank and blank still on reboot ( no time to cool down ), then the next day the LCD displayed again ( cooled down over night ). Appears to be directly related to the over heating problem.
But if the display problem progressed to the point that the PC would boot up cold and the display was still blank, then I would think your graphics card will need repair.
