I hate to say it, but I've never done anything more complicated with the
hardware of my computer than installing the PC transporter card. I'm not
very good at hardware repair, and have no experience with
televisions/monitors.

How complicated is what you're describing? I've never opened the monitor
up, and I'm afraid I may not be able to get it back together. That
happened when I opened up my origional AppleDisk 3.5" disk drive after the
eject mechanism went nuts (constantly trying to eject the disk, not to
mention that when it first happened, it LAUNCHED the disk out of the dirve
and hit my cat)

anyways, your comment about if you don't feel comfterable working on
exposed electronics probably applies to me. I'm not a technition. I'm more
into the software end of computers, unless you think somebody who doesn't
know what their doing can do what you described.
