Have a JD that once in a great while will reset, usually when I push both flippers. The first time this happened I read everything on here I could find and I checked connector (I think) J101 on the power driver board and it seemed loose and fixed it that time. Since then it happens rarely but always at the most inopportune moment, ie friends over, middle of a good game, etc. I check the connectors but they do not seem loose. So it seems maybe those capacitors and bridge rectifiers I read about need to be replaced? If one of those components was bad wouldn't this problem happen more often? Thx.

Read the pinwiki link. I'll test the line voltage first. Since the first time it happened J101 was almost disconnected I may start with replacing that and those header pins first. I guess I'll go back to the original question and ask if it was caused by electronic components, would it be so intermittent?

Thx everyone for the advice. JD my only game but my brother in the Air Force (stationed in Hawaii)came for a visit. I came home from work and found out he had bought a NIB Metallica!!hes leaving it with me until he retires in 18 months! Who hooo. I think it will be awhile before I get back to Dredd.

In anticipation of major soldering ahead of me to fix this problem, I bought a new a Hakko fx-888d, Hakko 808, header pins and connectors, some caps, and bridge rectifiers. At first I wasn't going to follow the Wiki advice because I figured if I had to take the board out to check a lot of these things I might as well changed these components at the same time and I'd fix the problem whether it was a bad component or related problem like bad solder joint. But at the last second I thought "don't be stupid, follow it step by step". Pretty quickly I came to checking the screws that secure and ground the power driver board. They were a bit loose but not terribly so. I tested the machine and no resets. I played many games both normal and Super game, constantly using both flippers at the same time. No resets. Could it really been just that? They weren't that loose. I'm not completely convinced because my problem is intermittent but I played quite a few games and it played great.

In an unrelated JD question, will the ball sometimes fall off the deadworld before the crane picks it up? I don't have the mod. Usually it works as it should but once in awhile it will fall off the ring. Not sure if mine needs an adjustment or if this will occasionally happen even to the most well adjusted dead worlds.
