Looks like a "PC" chassis set. There's a 100 uf cap in the vertical circuit (near the vertical output transistor heatsink) that is a very common failure on these sets. When replacing, use a 100V high temperature (105 degree) capacitor. The originals were either 50V or 63V, 85 degree, and they failed often. Another high failure capacitor is the 100uf, 200V capacitor by the flyback. When it fails, it often burns up the horizontal centering control. I can't remember the value; but, there is another capacitor in the B+ line to the video output stage and if this capacitor opens, it will cause a smeary picture with one side of the screen being darker than the other. It will be a HV cap of at least 250V, probably in the 4.7uf to 22uf range.
