Hi,

Just an update, have fitted a brand new LCD panel (used old inverter & screen cable) and the laptop is up and running now.

Thought this may be useful info for someone else in the future.

Cheers,
Steve

Just in the process of fixing an A100 which works fine through the external monitor connection but when switched over to LCD using Fn+F5, the backlight illuminates but there is no display at all, just an illuminated black screen.

I suspect it’s the screen that’s gone and not the cable (have a screen on order) so will update here but I just thought i’d keep you posted with progress.

Any one else ever had this fault and fixed it on an A100?

Julie,
It’s really hard to troubleshoot these kind of problems over the Internet without seeing the laptop. Try installing the old LCD screen back in place and find out if it makes any difference. You replaced all three parts at the same time. Did you buy this display assembly from a reliable source? Are you sure it’s good?
Normally, you replace parts one by one until the problem is fixed.
You said the external monitor works fine, so most likely the motherboard is fine.
If the laptop LCD has backlight but no image, I would check connections first. Make sure the video cable is properly connected to the motherboard and to the LCD screen.

Sorry, I cannot give you a better advice without seeing the laptop.

Yes, I replaced the whole screen, LCD, inverter, and video cable.
The old LCD is fine.
The LCD cable was damaged so I replaced the cable. When replacing the LCD Cable, the inverter broke. So, I decided to just replace everything. The LCD is from the same model.

Thanks for the reply!

Julie,
Reinstalling Windows wouldn’t cause this problem.
What was wrong with the old LCD screen you just replaced? Did you get any image on the old screen?

i unscrewed the hinges and connected the video cord to the motherboard. The screen powers on but no display.

It sounds like you’ve replaced the whole display panel assembly including LCD, inverter, video cable, right?

I just installed my new lcd. I did not touch anything in the lcd, i unscrewed the hinges and connected the video cord to the motherboard. The screen powers on but no display.

When i toggle fn and f4 with an external monitor all is well. I just cannot get the display onto the lcd itself.
I am going crazy trying to figure out what is wrong with it. Any suggestions?
I just reinstalled windows, could this be the problem?

chris123,

I thought that maybe you could tell me a practical way to test the integrated video on the motherboard!

Unfortunately, I don’t know any other way to test the integrated video at home.
That’s the way most technicians use. Minimize the laptop as much as you can, install known good RAM, install known good CPU if you can find one and if it doesn’t help, replace the motherboard. Even if you can confirm that integrated video is bad, I doubt that you can fix this problem at home.
