Zenith problem 9-160-08 module

[Chad Hauris]

Recently I was given 2 early 1980's Zenith 19" sets...one has Space Phone, the other does not. One of them had no green and one (The Space Phone model) would not stay powered up. Shuts down after about 30 secs. I got the first set going by exhanging the video/CRT module out of the one with the power problem. Resoldering the resistor pack didn't help.
Just wondered if you had some suggestions for common failures on the 9-160-08 module? Common bad caps?
