ok i have a 1966 or 1967 solid state b&w tv U90801 FA date 10/66 i got it for 10.00 but of course it dont work.
well i jumped the circuit breaker to get it to turn on and there is a coil under the chassis that started to make noise and i saw the wax begin to bubble so i shut it down (it was on for about 10-15 seconds max).
so looking at where the coil wires go (yellow and red)
yellow wire goes to a 350uf 100v section of a can cap
red wire goes to a plug on the chassis that goes to the yoke
so i figured it had to be a bad can cap so i replaced the cap with the same values 100uf 75v
350uf 100v
350uf 100v
well fire it up and the same thing with the coil heating up.
so i checked the crt with my b&k crt 400 (i know most people dont like this model) well it read that it had a short (open G2 first anode) and no emissions.
so i did the rejuve and i cleared the shorts but emissions is about 200ua it says 300 -1000 is good. however ive been told my 200ua is decent for a old b&w tv.
i have pics i cant seem to be able to deleate my old ones to post these. so anyone curious i can email you pics.
im also ordering a manual for this tv but that takes about 2 weeks from mike at vintage audio manuals.
a little about me im a vintage nut ive worked on stereos a good bit but this is my first atempt at fixing a tv ive read a lot of books on vintage tv repair lately. im 27 and really want to learn this trade that some you have done for years mainly for myself or friends. ive been real heavy in to old cars and there has not been a real challenge for me in years. so i figure tv's are just cool i have learn more.
well i thank you all in advance for any insight to my problem.
