I seem to have fixed the problem...However this is not for the faint of heat or the electronic novice. As I said in my original post I just upgraded my Armada 1750 to Win2000Pro but the screen problem was getting worse and worse. So I took about 90 minutes and took the computer apart. BUT THIS MAY HAVE NOT BEEN REQUIRED READ POST COMPLETELY! If you want to do this I suggest a small straight blade screw driver for the case screws a set of jewelers screwdrivers with phillips heads, a pair of cosmetic tweezers and a maybe a small pair of needle nose pliers. So I removed all the case screws and took the battery, hard drive and floppy drive out. Then I took the screen off. I removed the keyboard and the ribbon cable and then took out layer upon layer of circuit boards until I could finally see the traces running to the white connector, which the monitor plugs into. I took my 8x loupe and carefully pushed white plastic connector holder while I looked for any breaks in the solder joints leading to the connector. Unfortunately I would have had to take even more boards out to make a more thorough inspection. As it happened I found nothing wrong. I checked the monitor side of the connector and poke around with a super small screwdriver (you could use a fine paper clip) to try and tighten up the wire to clip connection. I put it all back together simply hoping the computer would just work as well as did before and to my surprise the screen did not falter after boot-up and has not shown any problem since I "fixed" it 2 weeks ago now. On first boot-up I had to make some selections in the boot screen since I had added memory during the upgrade and the BIOS was not recognizing it since I removed the battery during the “fix�. Anyway THIS WAS ALL POSSIBLE WITHOUT TAKING THE COMPUTER APART! From what I can tell, unless I jiggled something else when I disassembled the whole thing; All you have to do after removing power and the battery, is remove the left monitor hinge cover (1 screw), carefully pull the white connector plug (with tweezers or needle nose pliers) and simply apply a very tiny amount of pressure to each pin in the connector to ever so slightly bend the pin so it may come in better contact with its mate. Also use the fine paperclip wire and make sure the wires on the monitor side are firmly connected to the embedded clips. It currently my belief it was a connection problem I unwittingly fixed. I have heard of others claiming it was an overheating problem with the video board and in one case the guy had it replaced and the problem came back shortly after. Good luck with what ever you do but if you are in the least bit unsure, get someone competent or find someone who has balls and will buy you another laptop if he screws yours up!
