Quoted from RVH:I took my cpu board and put it in another TZ and it boots fine.
When I got home and tried booting my game again I noticed some thing I should’ve seen before.
The 12V LED is not lit on the power driver board, And no 12 V light on the driver PCB board.
Absence of +12VU results in the "check F115 and F116" message. Absence of the +12VR results in the "check F114 and F115" message.
Factory reset (due to removing power to the SRAM thereby cause a RAM checksum error at startup) causes the "factory settings restored" message. Unfortunately this message takes precedence over the "check F114 and F115" message. With the absence of +12VR no switches will be detected - even the direct coin door switches. That's why you are seeing what you see.
Part of the reason why I put a (yellow) LED on my CPU board so that it's obvious that you're missing this critical voltage input.
