Hello everyone I am having a very frustrating issue on my roadshow. So everything was working fine when one day the machine just rebooted itself while in attract mode after being on for about 2 hours. This continued to happen ranging between 5 seconds to about 1 minute between resets. The DMD is showing random garbage as well.This was not caused by hitting both flippers together but rather just when the game is sitting as in the video... So far this is what I have done.
Checked the 5v on the board and it measures as it should.
Replaced BR1 & 2 as well as C5 and C4 caps.
Jumped the legs on the Thermistor. No help.
Checked and reflowed solder on all male pins on the Power driver board.
Switched the DMD with a newer one that I know is not gassing out. (remained garbled) I should mention that I bought the machine with a rottendog DMD board that the previous owner said was about 2 years old..
Disconnected all the connectors and ribbons from the CPU board except for J210 and tried watching the 3 leds... Everything boots then resets on the cpu so it seems as the problem is isolated to that board correct?
Anyhow I am really stumped and tried looking through the forum/internet for anything remotely close to this problem. Anyone have an idea? Thanks for any input you might have, anything is helpful!
Here is the video.
