Hi all,
Just wondering if anyone can recommend a good pinball repairer in the Newcastle NSW area (Australia). Would consider mailing component if outside of this area and home visit not an option.
I'm quite handy fixing various parts and have done flipper rebuilds, replaced smaller circuit boards with new, pulled apart and rebuilt drop target assemblies, replaced motors etc. Have even had the machine (Williams Indiana Jones) stripped bare and thoroughly cleaned and replaced all rubbers and broken plastics. This one I have done several times as a general maintenance routine. So I do know my way around a pinball having self taught myself over the years.
Where I do NOT feel comfortable is any major board work so need someone to check and fix an issue I am having with the IJ resetting itself intermittently.
From the research I have done I'm betting that it is a bad BR2 bridge rectifier associated with C5/C4 filter capacitor, and marginal terminal pins on connector J101. Seems as though replacing BR2 bridge, C5 cap, C4 cap, J101 terminal pins at the same time usually fixes the problem BUT am a little uncomfortable doing this myself. Plus I figure a technician could do some other checks on the boards that I simply have no idea how to do - nor do I have the tools.
So if anyone reading this has used someone they could recommend that would be appreciated. I have googled a few in the Newcastle, Central Coast and even Sydney areas so have some options but thought I'd see if anyone had any first hand experience they could share.
Cheers, David.

Hi,
I can't help with a referral, but I would suggest making sure all board ground screws are in place and tightened down.

First thing I did actually. And everything tight and nothing moving. Interesting though. A few months ago when I first noticed this the board was loose - I could actually move it back and forwards - and the screws were loose. Tightened them all up and no further issue. Last few weeks the problem has resurfaced so checked all screws and all tight. Yesterday I played a few games and every time I had 3 ball multi ball - bang reset - so the extra flipper usage and other load would suggest to me the power was overloading. This happened about 4 or 5 times in a row and only when I had the 3 ball multi ball happening.

Rarely is it BR2 & C5. Connectors usually. Worse worse case, get a Kahr
board. While this will not fix the issue and only mask it, it will stop
your resets until you can find the issue properly without shotgunning
unneeded repairs.
