GE Portacolor II needs help

I have a Portocolor II with the 10JA chassis that's dead. When I got it, the 0.5 amp fuse for the +135v supply was blown. I replaced it and it blew again. I believe I found the culprit, the .047 1600v cap, C236 is dead shorted. That .0043 isn't shorted, but I don't trust it so it has to go too.

The horiz output transistor, and Y206 & Y208 are not shorted. Anyone familiar with these things that can tell me if it's safe to just replace those two caps and try it out?

Sorry for the poor quality of the schematic, it's the one that's pasted onto the inside of the back cover.

Thanks for any advice.
