Quoted from jamex:Hi, I have a problem with my IP. While playing, the pinball is switched off and only the GI is switched on with the display off and the 3 lights on the CPU board turned off. After 5 minutes, it restarts regularly
Sounds like your 5 volt supply is bad. I had to replace the capacitors on the main power supply board a while back and had the same symptoms. Easy way to check is to get a voltmeter and check the voltage at the test points. They are located on the power supply board in the upper right hand corner. The voltage is listed right on the test point. GI only and no dmd means you are not getting 5 volts. Check that one first. If not 5v, look at all the smaller capacitors on that board to see if any appear to be leaking. I think the ones responsible are C2 and C7 if I recall correctly.
