zenith-what happened?

[sampson159]

just pulled the back off my 1991 zenith console set with audio problem. cleanl
as a pin,however,so many cold joints. in the audio alone were 15! thin circuit board and low budget caps. i changed 5. they were borderline,so get em out.sound picked up nicely and set has a great picture! for about 3 hours,then video problems. more joints-just going to solder entire chassis this time. what happened to "the quality goes in,before the name goes on"?
