Alex,

I have a problem and I can’t figure out what the problem is. It started with a dim display. I tried another inverter but it didn’t solve it. I could use the laptop with an external monitor but now that doesn’t work anymore. The ext. monitor won’t start up(tried it with several ones) so I’m afraid my video card might be broken as well now. Windows works, I can hear the login sounds. Could you please give me an advice? Any clue on what the problem(s) is/are?

It sounds like you have two different problems in one laptop.
Do you still have a dim image on the laptop screen? Did you try reconnecting the video cable connector on the back of the screen?

Hello, I have a Compaq Presario V2000 laptop. My LCD screen started getting a red tint all over the screen so I replaced the LCD cable in it. Though, after that, the whole screen became dim so I couldn’t see it even when it was still showing.

So, I looked around and bought a replacement inverter for my laptop but got the same result. Then I bought a brand new LCD monitor and surprisingly didn’t work either. I tested the new LCD on my dad’s HP Pavilion DV1000 and the backlight turned on from pressing the lid close switch. I also tested my LCD cable and the inverter and it shows that it works on the other laptop as well.

Could it be my lid close switch that is causing the problem? I can still press it to make it go to standby but the backlight doesn’t flash on. Thanks in advance!

I have a sony VAIO laptop which lately showed signs of a screen problem. During a cold boot everything works fine, but when i start to reboot it, the screen shows only a white blank screen. I can hear Windows starting normally but you see nothing on the screen (only white). This symptom has been on for a while that even a cold start would show also a white screen. I tried connecting an external monitor and everything worked fine. I have replaced the lcd screen with a new one but the problem still persist from time to time. Could this problem be related to a bad inverter or backlight? Are there other components that would affect this problem like power supply, battery transfer switches etc? Appreciate the help, thanks.

hp pavilion dv9000 – turn on and backlight flashes and goes out. I can switch to external screen and see everything fine. When I try to switch back to computer screen it “pops” and flashes for a moment and then is black.

On the laptop display only faint shadowy image. I replaced both the backlight and inverter – same scenario. There is a periodic (once a minute or so) grinding/buzzing emanating from the laptop near the dc power jack. Any ideas? Thanks!

PS – when I tested the backlight after the replacement of the same and the inverter it worked until I put everything back together.

zeth,

HOw much does it normally cost to have the Backlight replaced alone in my laptop?

It depends on the laptop model and repair shop. You have to research.
