    Thank you very much. I have tried the FN + F8 to increase brightness to no effect. Can you tell me how to find the inverter--what it looks like? Is it easy to pull out? Thanks so much.--Chris

    The Compaq Presario V5204 NR screen is completely black. No image at all, but sound works fine. The unit looks impossible to take apart to determine if all internal cable connections are secure. Any suggestions short of sending this back to HP for a gouging?

    Thank you very much Joe! I will try to fix it via your links and let you know what happens. Regards, Chris

    Sounds like your Inverter, which controls the contrast and brightness, is bad. The inverter is inexpensive and usually easy to replace.

Dear forevencris,

I was able to fix the problem with the "black screen". I took apart the machine which is quite tenuous to get at the cables attached from the mother board to the screen itself. One of the ground cables was crimped and I repaired with a re-solder. Also, the main display cable was not seated properly. After reseating and re-assembling, all works well.

If you are good with a screw driver and small screws, you can do this. Be REAL CAREFUL not to damage any of the electronic or mechanical components with an errant screw driver. Be real patient and plan on at least an hour to perform this surgery.

Contact me for assistance should you desire. Good luck.

Best Regards,
Tom

I could not find your model's manual, but this show how to replace it on a Compaq V2000 which should be similar and should give you a good starting point.

The screen on my compaq presario cq56 is black


The problem is caused by the inverter board, "just below the screen" is more than likely the problem, or it is the backlight behind the LCD display, "built in" less likely.

While using my compaq cq61-412nr notebook my scree will suddenly go blank when i open and close the lid a coulple times it returns then blackouts again


It sounds like you have a bad LCD DC inverter board. This device low voltage DC current into high voltage AC current, which is required to power your LCD screen's back light. Here is a simple test to determine whether your DC inverter board is bad:
1. Power on your computer 2. If the screen initially turns on, either wait for it to go black, or perform any action that you know consistently makes it go black. 3. Find a standard flashlight and shine it directly at the screen. If you can see your display with the light shining on it, then your inverter board needs replacing. You may need to maneuver the flashlight to a particular angle to see the display through the glare of the flashlight on the screen.
Replacing the DC inverter board is inexpensive, if you are moderately experienced with the mechanical aspects of laptop computers. The replacement part will run you between $20 and $40 (here is one that fits your computer for approximately $20: http://www.zlectronic.com/product/For-Compaq-presario--cq61-412nr-Laptop-Lcd-Inverter-Display-Replacement.html). You should not attempt to replace the component yourself unless you feel confident about what you are doing. If you feel better having an expert perform the job, consult different computer repair shops in your area for a price quote on the labor. Be sure to let them know you will be supplying the part yourself; if you have them obtain it, you will almost assuredly be charged a mark-up.

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?
