As a young married couple, our budget was stretched. No room for extravagance like a TV. My dad's old TV was built with discrete components. The shop said $250 to diagnose and replace the bad board. He handed me the TV for free and purchased a new replacement for himself. I had the schematics. I turned it on and the problem was obviously sync. The sync board had 9 transistors. I used my VOM to check the EB junctions and found a bad one. A trip to Radio Shack yielded a replacement for $1.59. A couple minutes with the soldering iron and the TV worked again. I kept it for another 3 years util the wafer switch contacts had such deep grooves that the tuner was unreliable.

It is strange that with all of the electronics that we are now inundated with that fewer and fewer people seem to have a clue how to do anything with the hardware. I do have a couple of eprom programmers and various other equipment and tools, but I have to admit that all that I have ever done is repair stuff and build projects from kits and plans.

I am hoping my next project will be a CNC conversion on a small milling machine. I have a book with plans for building one up from scratch, but will probably get a kit to convert one of the X3 type mills Harbor Freight or Grizzly sells for a few hundred dollars. I always have admired people as creative as it sounds like you are.
