I would NOT change any caps in this set. It sounds like the VCR
is the problem. You need either a DVD with an RF output or
with an RF modulator to be sure. An old game console would also
work.
ALMOST ANY set made through the mid 1970's will bend at the
top with a VCR. B&W sets were the last to be improved !
For now best to put the $$ towards a cheap camera to post
screen shots. Many here can point you toward the right one
