I found a website showing how to remove the board and replace it through text and video. The site was very informative and didn't try to sell me an upgrade help service either.
Thanks anyway for responding.

Compaq presario v5000 dark screen and failing hard drive


The problem you described, is related to the inverter board.
There's a little board, that take care of lights on the monitor. You must replace the inverter board to solve the problem.

Here you have an image, of an inverter board.

The picture and sound come on then a few seconds later the picture goes off to black screen and sound stays on can you help please


hi,
Is there is any light in the screen at the time picture gose. If not, then Backlight inverter is faulty. All lcd tv have backlight to light the pixels. If you watch the screen very near then you will be able to see image on the screen. First of all check is there is any budged capacitors in the power supply. If there then replace it will solve the problem. If no then check the inverter board. Do on thing check the fuse in the inverter board. If the fuse is faulty then replace it. If the fuse blews again then the inverter board is short you have to replace invereter baord. It is not possible to repair the backlight inverter. You have to replace the board with a new one.Have added the picture of inverter board and budge capacitor for your reference. If you need any more assistance feel free to contact me by Fixya.

I have my compaq presario cq60 laptop and i got a trouble on my screen which is the brightness become low and i can not adjust using the fn key plus f8. how can i adjust to return on the normal...


How low has the brightness gone? If it is very dark and you can barely see anything on the screen, it may be that the inverter board has failed and needs replacing.

The problem could also be caused by the screen itself, or the motherboard, but the inverter is the most common solution.

Compaq presario cq61 screen went dark but can still see window faintly through the dark sreen.


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If no luck, try to remove battery and drain the power, then replace battery and turn on.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

How to replace backlight on compaq 2570us laptop


What is wrong with the backlight? The computer screen is just dark? I would start with the inverter. The inverter is usually the problem when the screen goes dark but people think it is the backlight. The backlight alone is very hard to change too. Go with the inverter, I would bet that is the issue.

Compaq r3000 dark screen


If you already replaced the inverter and the screen still continues dark, you need to replace your lcd screen. Your video card is good due you have signal with external monitor.
