Did you mean vertical columns of white and black?
This is usually a sign that the CPU has not kicked in. Has this machine had
an accelerator in the past? Perhaps the cpu socket is not making good

I have not heard of many people having issues with the IIgs capacitors.
They are not surface mounted and therefore avoided the bad caps plague.
