I have a compaq 700 series. The laptop boots fine but the screen has vertical lines in diferrent colors. I know it boots up and has no operating system problems because I connected a CRT to it and it looks excellent. I'm not sure if the trouble is in the LCD,inverter or the motherboard. Any thoughts ?

I would vote for the LCD. Depending on the model, it could be slightly expensive to cheaper to buy a new laptop expensive.

Just make sure you have the newest drivers for the display adapter. If that doesn't help, remove your display from the PC (you should be able to get the info on how to remove your display by googling). Now make sure the cable connecting your display to the PCs mainboard is connected properly. If necessary you should also be able to replace the cable.

Try running a dos based diagnostic program that checks your video adapter. There are several good free ones available. Here's a link to one that I use:

Run the video tests and see if there are any hardware errors.
Cheers.

My money would be on the LCD being faulty, particularly if the lines occupy a fairly well defined vertical strip of the display. This would suggest that either a vertical line driver is faulty or the bonding on a driver tab has broken loose. Faults like this can be fixed (the company I work for can do this), but success rates are very low, particularly in the case of vertical lines. Couple this with the fact that spare LCD tabs are practcally impossible to obtain, and salvaging tabs from donor screens is a destructive process then I'm afraid you're still left with a faulty screen.
