Hey guys

I have an Addams Family that for some reason is randomly rebooting, I have done all the pinwiki troubleshooting on the driver board, it has an after market cpu in it, but was rebooting with original as well. I can play and hit the 2 flippers, and it does not reset, so far bridge rectifiers have been changed, cap at c4 changed, voltage regulator changed to new style with the adjustable pot, and 5V is solid in fact it is 5.10. Game can just be sitting turned on for hours, then randomly it will do a reset.. I am out of ideas what to do with this issue, It also has an after market dmd driver board, but again was doing random resets with original board as well.. Hooked up to a voltage regulator that keeps power at 120V. Any other thoughts I would appreciate it, I do not know what else to try or what else to replace.. I did not change the 2 upper BR's or the other 3 caps on the driver board, all connectors are good and clean, no burns or corrosion at all.

Thanks
Steve

I am going to change the top capacitor and the C4 cap now, I had done the bridges already, checked all the solder points suggested, added a new voltage regulator to get it to 5 volts.. Going to try changing out those 2 caps now.

C4 changed and upgraded, now I just sit and wait.. been an hour with no resets, that is the biggest problems with random issues.. you just never know for sure you got it!

I will post updates, Several hours ago, game was just on, no one was playing, then it just rebooted itself, It has done this several times, I changed the Bridges, All the large caps, the voltage regulator, re soldered any questionable parts under the board, went through the pinwiki guide, only thing I forgot to change was C4, so I did. I wish I had a meter to test caps, just ordered one.

Thanks Faz

I was aware of this, I have made that mistake in the past, I bought a desoldering gun, to make sure I do not destroy any boards again... because I have in the past!

Well, 2 days in, I have left the game on all day, I have not been around the game the whole time, but I have not heard or seen a reset yet. I guess that last cap was the problem, I ordered a cap meter the other day, in a few weeks when it shows up, I will test the cap and know for sure.

Just an update, have not seen another reset since.
