i would suspect that the problem is indeed the floresent lamp. and though the replacement bulb is cheap this operation is not for the ocasional tinkerer... there is a lot os disessembly involved, but most critical are the layers of plastic that lay over the lcd panel which can easily get out of alignment and effectively ruin the display. i suggest you check out this lcd repair shop for reasonable rates to do the replacement for you... they also sell bulbs if you want to go that route.

Well, I hope to be able to fix this myself. I ordered the tube already and it should be here by Monday. As it happens, I ordered it from Moniserv. I am used to taking things apart, and am an EE, so I am hopeful. The display I took apart to try the experiment was very simple...the tube assembly just slid right out....no skills necessary. I will let you know how it goes.

some are easier than others, and i don't have intimate knowledge of the 700m bulb installation, but the problems i have had are not so much with the bulb installation (though i found soldering such a delicate thing in place a bit scary, not wanting to overheat it) but the film on the front on the lcd panel... if that stuff gets disturbed then the light just doesn't get carried across the entire screen correctly and looks horrible... but the great thing about working on something that is broken is that you can't make it much worse. best of luck, and look forward to hearing your success story.

Well Sh!t! I got the tube today and I must admit this was a very difficult job. I am very used to working with microelectronics (over 30years), but this had me pretty much beat. The tube on these is very difficult to remove. I was hoping for something much easier...like the display I took apart to test it. This 700m display is extremely difficult and without instructions, I would never attempt it again.

On the bright side (no pun intended), I did manage to replace the tube and it did solve the problem of the light going off after a minute or so. So if you have this problem SEND YOUR UNIT IN for a tube replacement! The laptop works just fine now except for one minor problem that I caused. Somewhere in the process, and I have no idea how, I managed to crack the display in a corner. I now have a working display except for a big hole in the corner....but the other 95% works.

Oh well. My wife has already ordered a replacement laptop (she did not think I could fix it) and it should be shipped this week. I guess this unit will go on ebay AS-IS. It would be a great server and it works great with an external monitor.
What a bummer!
