I think that is a CTC-15 clone. The only lytics are in the power supply, and I believe a few in the vertical. The reset Are mylar film, and rarely ever fail.

Looks like the green gun is weak, and you are missing most of your Y (video) signal. If your lucky and the CRT still has good emission, all you may have to do is replace the small amount of lytics, some tubes, perform greyscale and convergence.

After you change out the caps and tubes and get it running well, make sure to check the Ho cathode current. Anything more than 210ma and you run the risk of cooking you flyback.
