About 2 weeks ago, the computer touch screen on our G.E Spacemaker 2.0 Microwave went out. It is over our stove with the fan and light on the bottom of it. Funny thing is that while you can't see the screen lit up in green, if you touch the pad with your finger, you can get the microwave to work. We had set up a one touch 30-second button in the bottom right corner. We have been using it to heat....tapping it 4 times for 2 minutes of heat :) Any ideas if I should spend the $109 to have it serviced? Is this something that can be easily repaired? I guess I am wondering if we should repair or buy new.

thanks!
