/diy/ - Do It Yourself

>>1632409
I help out some people who throw street parties with a big old boombox collection. 90% of the time they're broken because someone dropped it and cracked the PCB. Sometimes it's obvious and other times I need to check every pair of points with a multimeter until I find a broken trace. You can also do this to identify components that are no longer properly soldered. The other common problem is electrolytic capacitors and the larger diodes and transistors used in power supplies failing.
