Amilo M3438g display problem

Postby keithp » Fri Jan 08, 2010 7:03 pm

Hello All, new member here.
Found this site while trying to research the problem I'm having with my laptop. Started one day while browsing the internet and the screen just when whiteish/brown hew, faded away and went dim.

After contacting several supply people regarding the lcd panel I've so far replaced the inverter and the panel. Now while the panel is not the exact same make/model as the original, ie a Samsung, it's a Phillips 1400 X 900. What happens is when the lap top boots, I see the bios display, and can go into the bios no problem. When it gets to booting xp I get the initial splash screen the just before the OS comes up it goes blank (dark). The output to an external monitor is fine and the back light can be seen on the panel okay, just no Operating System display. It does how ever display the boot up process no problems.

Does this sound like a duff inverter or maybe inverter not matched to the power requirement of the new screen, ie it blanks out when asked to show full resolution?

Regards

This get weirder by the minute, I've used the Windows Ultimate boot cd to boot the system, displays the splash screen on the lappy fine, as soon as it's finished booting the screen goes blank. That is no signal, the backlight is on okay.

Any suggestions anyone?

It sounds like your graphics driver isn't able to handle the display, because the moment when it turns blank is the moment when the graphics driver is loaded. If I'm right you should see the desktop if you boot windows in safe mode.

Cheers for the reply there, tried that and if I press f8 and just boot in safe mode it stays on the laptop screen until it boots but then blanks out as soon as it gets to the safe mode desktop. Its really weird. Remote desktoping on to it or using an external monitor the 6800 graphics card is showing 'Code 10' driver not started. I can uninstall the driver, re-install then it loads and fires the card up on the external monitor, I can then change the graphics to 1400 X 900 but when I then re-boot the card has stopped again.

I can go into services and start the nvidia graphics driver but as soon as I do it stops again, saying there is nothing for it to do!

I'm getting to the stage where I'm gonna nuke it and start again. I've never come across this sort of problem.

Well I just tried installing Windows 7, got as far as the load screen on the lappy, then it went blank when you get to choose country location etc. Still showing fine on the external monitor..


This one has me puzzled!
:(
