Hello all, I got a free Chromacolor II today that I need a bit of help with. The tv powers on but there is no picture at all. The tube lights up in the neck but displays nothing but darkness. I was told the tv worked fine in 2010 before being stored in a closet, so I was guessing a cap issue.

My thing is I just do not know where to start with tvs since I mostly do vintage audio. Any help is really appreciated.
