So if the chip is fried, what could be causing it?

Also as a side note, yesterday the neon did come on again for a minute or two. Since I have had this game the neon has been a bit suspect. I would have to turn the game on and off a few times to get it to work. Hope this info helps a little

Typically an unexpected current surge onto the PCB ruins the 2803 chip. Something touching or grounding on the underside of the playfield that shouldn't be perhaps (solenoid to switch) or done while working on the machine with it switched on?

The fact the problem has come back after a week even with a new PCB installed would indicate there is no point replacing the chip until the grounding cause is located (if indeed the chip is the problem)


So in the neon test under the test menu, the neon does nothing?
