Dark, To Doctors soon means 1-10 years.
Tiarra, I have a pretty good ability to fix a lot of things, but many people get stuck when some simple electical problem becomes a electronics thing. I did go back to school in the 80's to learn robotics, and have a good understanding of sensors and mechanical things that controlled the robot, but fixing the electronics and the circuit board problems took an electical engineer. WE had a full time electician for those things. He had the ability to trouble shoot the circuit boards, that the company used to just switch out, and sent them out for repairs @ $1000 per board.
Part of having things sent out to be fixed is the ability and honesty of the technician. Either you pay through the nose becasue a problem was very hard to find, or you pay through the nose becasue they found a $2 part bad, but charge you for a rebuilt circuit board. I boils down to if its cost effective considering the total age of something. If you have the ability to fix it onyour own, than its worth the time and effort. How much should you spent on a applicance thats 15 years old vs. justing buying a new one you can hopefully depend on.
