Today in the Den, I was finishing off my Spectrum Analyser project, a neighbour came around with their TV,which would switch on then turn off after 5 minutes approx,so I took a look, found fault straight away,our old friend Electrolytic cap spilling it guts out over the board, I cleaned up the board, put in same value, but higher working voltage cap, works perfectly, I'll never be a businessman because I gave it back with no cost to the neighbour, I enjoyed the distraction,which was good enough for me ;) Another repair under my belt

Consider your karma value increased though. I tend to look at TV sets and the like as either disposable or not repairable easily.

A lot of consumer electronics are like that, but it does of course depend on what the fault is. I find things like loose connections or fractured joints etc to be fairly common, and of course, many people find electrolytic caps to be problematic.

Actually Sean I do believe in Karma,and do try to live my life accordingly, the caps that they used working voltage was within a volt of the power rail,so I would imagine they dried up,and they were called CAPZON, or something like that,I put back in Rubycon which is what I use and like,and double the voltage,but same value.
I don't do much with TV's,I spend most of my time building my own test equipment, and Radio Amateur related circuits, especially 6 Metres,I have a transceiver project in mind for that. Ition know from past conversations you are also a ham,there is a book by Eamon Skelton EI9GO, called building a transceiver,good read.

That has not worked out for me all that well!
