I have a Hollywood Heat that sometimes plays fine, and sometimes resets. It also will lock up and not boot sometimes as well. When this happens, there is nothing on the score display, and about 10 or 20 lights on the top half of the playfield play through in a chase sequence, like a severely crippled attract mode - but with no sound and no display. Usually I will have to power it off for a while to get it back to working.
I have read through Clay's repair resources, and followed the trouble-shooting. The MPU is getting 5.1V. The lock-up happens when the external reset board is not plugged into the MPU. When the game is locked up, the +5V on 6502 is pulsing, about every second or half second.
So finally, my question. Does this sound like the watchdog reset section of the MPU needs to be rebuilt/replaced? I cut the original battery off, and there did not appear to be any leakage. But I know that it can be difficult to see. I also know there are eleventy edge connectors that could be re-pinned or replaced, but before i jump into that, I am trying to focus on one thing at a time.
Anyone have any thoughts?
