Defender..no response from anything inside the door
So I'm trying to bring my defender back from the dead...the game was on loan fr the last 13 years thus I wasn't expecting much when I got it back Here's what I've done..
I installed a switcher (just for testing now.. I'll probably rebuild the PS) The switcher is a Bob Roberts thus he did the wiring for the Williams stuff. With this I at least got the machine to boot but it went right to the rug test and stayed there
I reflowed the pins on the main PCB and the ROM board. I now get what I remember as the boot test screen where it asked to press the 'advance button' to run through the test
The 4 lights on the ROM board blink twice then stay off (couldn't fine anything on a search here for the 'blink code')
I've tested continuity from the coin door wires to the ROM board.
So right now the game boots...all the lights in the coin do work fine however none of the test buttons work
I'm thinking possible a ribbon cable issue or maybe the ROM board it self?
