Make sure that the the two tracks as shown below have continuity. I often find with these they look good visually but there's no copper under the mask! You can see that new pieces of copper have been cut and shaped and riveted and soldered to the existing track. All the components along the bottom to the right of the battery should also be replaced, not forgetting the little caps. Apologies if you've alredy done this, hope it helps. Also the 15 way PSU connector if it's bad like this one don't bother trying to clean it, replace with new pins otherwise you'll be plagued with intermittent faults!

The problem is the touchscreen is part of the glass,so a new touchscreen membrane would mean a glass replacement.so make sure touch screen is OK on replacement glass.looks a great machine.

In the picture, I have highlighted the Optos and prisms. The opto are on the coin mech. The prism is on the removable cover. The prism is to reflect the opto light back to the light sensor.

I’m sure(not 100%)I have a copy of piggy bank iirc the machine is a converted road runner I will have a look later on
