Having problems with your PC Desktops ?

I have a HP Pavilion laptop ze4900. Every time I move th screen, the display either goes off completely, or it goes vey dim and I cannot read anything from it. The only thing I can do to get a display

\015 I have a HP Pavilion laptop ze4900. Every time I move th screen, the display either goes off completely, or it goes vey dim and I cannot read anything from it. The only thing I can do to get a display again is moving the (lid) screen slightly and then keep switching on and off the computer until I get a display again. I try my best not to touch the monitor lid in order to preserve a video signal to the monitor. I cannot transport it anywhere because if I close the lid, I will lose the display.\015\012Any possible solutions would be greatly appreciated.\015\012Regards\015\012Mike\015

Answers :

You could have a defective screen - a defective inverter or a CCFL lamp.
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:

\015\012
    \015\012
  • Screen flashs on red/pink and off. \015\012
  • Picture stays on in red and slowly be come normal. \015\012
  • Picture flickering with dim display. \015\012
  • 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.

Your monitor is dying... it will eventually go dim to dark quicker no matter what you do. The cheapest thing to do is just buy a new monitor and install it... they are cheap, under $100.

I had the same problem... apparently one of the cells are out and at that point you just buy a new one... Also, consider it may be time to get a new laptop... I have the same one and it's an old model... the life of it has almost run its course.
