NGL I usually only do component level repairs on the power boards (or in the case of appliances most of the components are easy to find docs for and are much larger) but I usually find stuff by poking around with my multimeter or looking for obviously blown things. But my experience is more from the realm of appliance repair (and all from experimenting).
Testing capacitors can be done (and if they're big enough) something I'll do as well. I ain't gonna test capacitors that are smaller that a grain of rice.
There are times though that it's easier to just buy a new board rather than do component level repair.
Good news is that when it comes to TVs those boards are usually really cheap.
that makes sense. appreciate it!!
