[TV MAN]

I know that many would just do the recap - but, something put the set out of service, then if the set has a bad unobtanium part, like that horizontal output transformer, or picture tube (you cant test or rejuv a 7JP4) there's no sense wasting the time or money going further until a part or parts chassis is located. Then, suppose you make a mistake - and the set doesn't work right, where do you start? On a TV, I always do a power up, then go for the the sweep, usually horizontal so as to get light on the screen, power supply then the rest shows itself where to go next.  I generally try to do one section or part at a time, then test. If it suddenly shows a problem, then I have a smaller area to look & check over for problems. On a TV, you might drop a blob of solder - say in the audio section that shorts out the B+ to the vertical or video. Well, ya get the idea. So, some may not like my technique, but is how I'm comfortable doing it. It also serves to help me learn symptoms and causes for future projects, then there's the entertainment value  

On something smaller like an AA5, yeah, I test then bring out the shotgun full of caps But I might not on a big ole Zenith, 10 bands, 4 speakers, 22 tubes packed with layers of capacitors and those cute little strippey black capacitors always covered in oil
