You know steve if you aren't interested in helping then don't post, its
as simple as that. Tony thanks for your interest in helping.


Get a short length of appliance power cord and cut about an inch of it
off.
Then clean the coating off the traces you cut. Pull some strands of the
fine
bare wires out of the 1 inch piece of cord. Use a small soldering iron and
"bridge" the cut traces with the wire. Cut off the excess. Using a decent
solder and some good soldering flux will make this a lot easier. Be sure
you
have a good light and a magnifying glass to check your work. Clean the
repair with alcohol to get any remaining flux off. If you're real careful
you can clean the coating off the board and cut the excess fine wire with
a
X-acto knife.

Assuming that only top level traces were cut. Many motherboards have 6-12
layers in the PCB. You will not be able to fix inner level traces.

Assuming that no traces had critical timing signals which adding repair
traces will change the impedance and screw up timing thus cause crashes if
it did ever boot again.

Best bet is to try and salvage the LCD display for some kind of project or
desktop monitor.
