The Beauty...
It's like stripping a motor down and finding a part that's bent or burned and straightening it and the whole motor runs again.
These days you pull the DFI computer and put a whole new one in.
Or you toss the TV and get a whole new one. No incentive to repair stuff anymore. The pace of change is so fast you want the newest bestest gadget to replace your old dead one. In the "goodolddays" we just wanted the dead one working again.
Ah, progress...
