    the hot screen LCD is a bad screen
    any tech knows that.?
    as is lines, and changes as you twist the screen, see bad LCD.
    the inverter is power, only, not data.
    tell the customer the bad news.
    find new LCD panel. for $50 to $100
    this PC sells for $10 , uses as/is, broken
    that is its street value. !!! 10 bucks.
    (means junk class)
    so tell the customer the fix is 5 to 10 times value of PC.
    buy newer working PC is far far cheaper.
    buy a PC 2010 and newer, and avoid your above
    CCFL back lamps like the PLAGUE.

SOURCE: Aspire 5102 WLMi display replacement

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

SOURCE: Compaq Presario R3000 dim screen but not dark

Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.

SOURCE: lcd screen black on laptop. External monitor works.

Defective CCFL backlight may has 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.
  • 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.

SOURCE: my compaq preasrio r3000 black screen cant conect to an external

have you any other A/V ports out ie Svid etc if so try that via an A/V lead, if that works reset your bios settings to minimal settings, if that doesnt work search the 'net someone somewhere has had the same problem! try shining a flashlight/lamp onto the screen whilst booting up, if you see anything on the screen then your inverter is definatly gone and yes it could still be your inverter! your laptop may have software/hardware issues with an external monitor?

SOURCE: Black corner on laptop screen and burnt smell

The problem you have is caused by a defective LCD inverter.
They really really fragile and the job of replacing them can be quite tedious.
There is not other reason for your screen corner to became dark.
Send it back and tell them that the replaced part is defective or it was not properly installed.

I hope this help you out.

White Screen Compaq Presario CQ60


Regarding ; White screen , I flipped my notebook over and removed the power source(s) , power cord and battery. I then removed the three screws in the battery cavity and the two outside corner screws to gain access to the connection for the LCD and found a loose connection. It seems that the wire that connects to the screen was being moved every time I opened and closed my computer. So very glad to find that bulb and inverter board was not bad. Prior to this , I did try external monitor and found that all was okay as far as operation of start-up.

I have a Compaq Presarion CQ60-114E and I have a Black Screen


You simply need to replace the screen, and or backlight, it is a relatively easy job, as long as you get a service manual. I usually get my screens from eBay, or similar.
