What's up with my Mega-CD, can you help ?

This is my (PAL) Mega-CD I picked up several years ago off eBay... although this was supposedly "tested", I later found out from the seller that this part wasn't and he assumed it was ok. So I ended up getting a few quid in a refund, but it really doesn't work. I think I've managed to get it fired up once properly, and since then nothing.

I've blown and replaced the internal fuse, and I've replaced all the capacitors as I read they can get a bit flakey. About every 6 months I decide to have another go at fixing it, but I've run out of ideas and/or expertise in what to do next... can anyone suggest anything.

The video I've got here shows what happens when I turn it on, basically it seems to freeze before the full BIOS sequence has run. We should get the Sega logo bouncing around.

I also turned it off to change my Megadrives switches to 60hz/NTSC region, just to show that the Mega-CD can at least recognise if it's attached to what it thinks is a US system in stead of a UK one

If I let it boot (or at least partially boot) to the mega-cd screen (so no cart in) and then press reset, I just get a blank screen - and I need to opwer off/on before I can do anything else

Could be a fault with the CD drive or controller. This is a guess based on what I think the BIOS does when you turn the system on and the fact that your MD is working OK with regular carts.

Does it respond to pressing the reset button?
