Laptop LCD screen issues. help??

gosh1976

I've been trying to get a compaq presario 2100 laptop to work. The LCD screen was very dim so I changed it out with a different used one - still the same result so I tried another one - still the same. Now when I first turn on the laptop the compaq splash screen comes up and you can see it just fine for a second then it dims. The fn2 key to brighten does nothing. Plugged into a monitor it is the video is fine in the monitor.

Any ideas on this?

Sounds like an inverter board issue to me. Did you replace that when you swapped out the screen?

Isn't the inverter usually behind the screen bezel? I took it apart at the hinges and replaced the whole top half...

Some LCD screens have the inverter board attached to the bottom. This link shows a picture of it:

New LCD Inverter For Compaq Presario 2100 2200 2500 Series Laptop display -- For 14.1-inch or 15-inch LCD displays

Did the used LCD you purchased include that part? If not, that may be your problem.

We had some old used ones in the back and you can take those compaq's apart at the hinges without ever taking the bezel apart. I think it was just a loose wire it's working now. Thanks!
