1986 Fisher television

hi all, i finally found a Fisher PC-420 television i've been hunting for and it has some issues as expected.

the tv has what looks like barrel distortion the corners are pulled in on all 4 sides. also has some lines at the top of the screen that look like vertical comb over.

the vertical/PCC control board is separate from the mainboard. it has two electrolytic capacitors and a film capacitor. all were good but i replaced anyways. it uses a C2168 and A958 transistor which all check out. it appears the transistors are getting ~27 volts and the board itself is getting 89-90Volts from the mainboard.

the PCC transistor is okay as well.

i do not have a service manual for this TV and cannot find one. i'm not an expert in CRT's but i have some electronic knowledge.

anything else i should look for?

thanks
