Pawel, Black screen usually indicates a deeper problem than a cap. +5V good? -5V good? activity on the CLK signal at the processor? check that data and address are toggling @ the main ROM and RAM sockets? pull and reseat ROM and RAM modules?
just a few suggestions. Do you have something like a scope to be able to look at signals?
