Flat screen Power supply repair
LOL I was talking about circuit diagrams, AKA schematics of the TV
Hell at work I must use lead free solder. THAT was a learning experience. It is much higher temp than lead based, and you can really melt stuff if you aren't careful. My surface mount talent has increased even in my old age. I still can't change the microprocessor in the drive module, to. They are pretty "dense."
A little it of what I do. These are cropped shots of the main drive modules for the wheelchairs we build
Below are a couple of caps and a resistor. I can replace these easily, that is .031" solder for size comparison
Below is the microprocessor, again with .031" solder. I cannot reliably replace these
Below, you can see that .031" solder is WAY bigger than TWO of the micro leads. We have smaller solder at work, I believe it's .010"
Below, another shot. The big buss bar at the left I install, using a huge 250W American Beauty "old school" iron. Likewise the terminals coming up from bottom
