       Are you sure the problem is in the computer?  I had a similiar
    problem with one of my 800XL's a while back, and the solution was to get
    a new power supply.  Now it works fine, and I never had to open the
    computer (although it's been opened for other things... :)   )

I had a similar experience.  My girlfriend's 800XL was acting very
peculiar; screen changing brightness, random funny characters displayed,
wedging up for no apparent reason.  It turned out to be the poser supply
connector, it the little DIN plug that plugs into the back panel of the
machine.  Replacing the plug solved the problem.
