I'm in the UK England, I get all of my electronic components from ebay - uk

Here's your HOT - http://www.ebay.com/itm/2SD869-Transistor-/291259901875?pt=LH_DefaultDomain_0&hash=item43d07167b3

You should find the transistors on ebay also.

The Flybacks I get from Steven at Arcadeshop.com

I've never had to replace these but here's the part numbers

TR402 - 2SC2073R
TR403 - 2SA940R

Here's a link to the Sanyo EZ manual

Im reading something about convergence adjustments in the manual. could there be something wrong with that, that could be causing a problem with my screen?

Don't touch the convergence rings man or you will really have a problem.

Great news, glad you got it going. If you haven't already, check your B+ voltage.

As for your game pcb, that's not really my bag but I would suggest lifting, cleaning and reseating your ROMS. This can cure a multitude of problems on DK/Jr boards.

It may well be worth doing that to all socketed chips, be careful when putting them back in their sockets though as it's easy to bend/snap the legs.

Good luck
