Mega / Sega CD 1 - Not powering up, not fuse related.

[nebno6]

Hi there im new to the forums, ive read around for the last hour and cant find any one on the net having my problem.

Using Megadrive 1 PAL + Mega CD 1 PAL

I have replaced the fuse and know its working because: 1 the heat sink heats up + 2 the laser assembly moves back to a default position when moved when off and then switched on.

Problem is not the power supply (tested 2), fuse (replaced), megadrive (tested 2), or contacts on ribbons or MD to MCD conacts (cleaned).

Sounds like a blown cap to me but i have no idea which one, any ideas.

Thanks in advance.

EDIT: to clarify when plugged in + switch on etc. nothing happens, no disc spin, no LED allumination.
