I've fought cold solder on hundreds of chassis. in my 30 years of experience,
the best thing I've come up with is a chop stick. it has a small point so you
can localize the pressure to smaller areas sometimes you can drag it lightly
across the solder side of the board. i happen to agree with you in that there
are only a handful of times when a scope has been useful in helping me locate
a cold solder joint. i also use a very high power optical head set to spot at
least 70% visually. also in this case i might have responded to your original
e mail if i knew it was a ctc146.i list all my GE and RCA by chassis. i have
considerable notes on ctc146 and bad connections
