    My m60 has started showing a strange problem. On cold reboot from powered off the system shows the bios boot up display and the windows xp startup logo as normal. However as soon as the os loads the full display driver (i.e. just before the xp login screen appears) the display goes blank. This is not a blue screen or a white screen but it looks like all power has been removed from the lcd matrix and what you can see is the back reflective surface illuminated by the back light but viewed through a totally transparent lcd matrix. The system meanwhile appears to continue to boot up normally. If I then power off the laptop by holding down the power button and and then reboot and use F8 to select boot up in VGA mode the system boots up normally (but into VGA mode display). If at the XP login screen I tell the system to reboot and let it come up normally it boots up perfectly into full high resolution video mode!

Ok, when connecting to another monitor, be sure to use the Function Key, and press the appropriate F Key to enable an external monitor. Without doing this, you will never see an external picture.

If that picture is fine, then yes, you need to think about your video card, and I would start with updating the driver.

This could be a faulty CCFL lamp.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Sounds like your screen has developed a problem. You wouldn't necessarily see any damage when you opened the bezel up. I would suggest you take it to a repair shop and have them test it and replace the screen if necessary
