Only thing you can do in these circumstances, besides moving your screen around position wise to see if it's a loose wire, is send it in for repair.....

unless of course, if you feel confident with opening the machine up, you may want to check to see if the cable connecting the screen to the motherboard is plugged in properly, and not loose/coming off. In my experience, this is most often the case when you have extreme discoloration- the pins can become loosely connected over time. However, opening the laptop up will void any warranty you may have on the machine.

There is one screw on the bottom of the machine that removes the CD right above the memory cover. It may even have an icon of a CD for it. then it should slide out the side.

No Display


First make sure everything else is getting power and operating okay, and that it is only the LCD display that is non-functional.

If you get no video signal or power at all, even at boot time, you probably have a dislodged ribbon cabling or power connection. Usually when LCD monitors go bad they show colour banding or all white, etc., but usually continue getting power.

As a last resort, try disassembling the lower case (with the power disconnected and the battery out of course) to expose the LCD monitor mounts, and then following the wiring from the screen into the laptop and check for anything loose or disconnected. You could also have a loose ribbon cable going into the LCD array, which will require disassembling the LCD cowling and mounts.

If you are handy and comfortable with electrics and find nothing loose, put the battery in and test the power line going to the LCD backlight, which should be getting above 7V (I think). Below that and you either have a bad video controller or bad wiring/solder joints somewhere. Otherwise, if the unit has been dropped or had a hard life generally, it could also be the connections between the LCD connector bus on the monitor array and the array itself. As a last resort, try unplugging and reconnecting all ribbon and connector cables, cleaning the exposed brass coloured runners lightly with rubbing acohol or even a pencil eraser.

Good luck...
