Hi all,
My JP has been resetting, at first intermittently, and now all the time and can't play a full game. Checked the voltages on the power supply, and saw that the +5v and -12v are fine. But the +12v read +9.6v, so that seems significantly low. Is that the likely cause of the resets? In looking around, I found a hack to deal with a burnt CN1 connector in the top right. The wire from that pin was cut, and I see a wire coming off the back of the board and connected to what is likely the cut wire from CN1.
So, is the low +12v the likely cause of the resets? Could the hack be causing the low +12v? Is the burnt CN1 a sign that something else is wrong? And how do I get the resets to go away?
Here are pix of the connector and hack to show what I am talking about -
Thanks for any suggestions!
