LP Battery Machines

[fencinman89]

Last week I discovered an LP battery reel that is about 7 years old and I was told that it was broken. When I teseted it was in fact broken. I opened it up and pressed on a few circuits, it started working again, after it had been broken for a few months. I am only 14 so afterwords I was trembling slightly out of excitment, does ne one have any ideas on how I fixed it. Because it was a total shock to me.

Likely, there was a loose connection that your made "un-loose" and now it works because the electricity is flowing to the right places. Welcome to the world of teen armouring. We are more underappreciated than carpet mill workers.

What is meant by "broken"? Was it not powering up at all?

It could be something as simple as the batteries having shifted a bit out of position, when you pressed down on the circuit board it re-seated them. If there was some dirt or corrosion on the battery terminals, re-seating them could have scraped it off a bit.

If there was something up with the circuit board, it could have been a cracked solder joint, and pushing on the ICs or components was sufficient to re-establish the connection. I can't recall off the top of my head if any of the ICs are socketed, but reseating a socketed IC that had managed to work loose would also resolve problems.

I've also seen an LP box acting up because a dust-bunny had gotten into the Foil/Epee switch and was preventing some of the connections at the switch terminals from being made. Clearing it out resoved the problem.

BTW, the first principle of troubleshooting flaky electronic equipment is to check the power supply (the batteries, in the case of the LP club boxes). If the power supply isn't providing the right voltage or sourcing enough current, you'll see problems. I'd estimate that something like 80-85% of scoring machine problems I see end up being related to the power supply.

So basically you performed low-power repricussive matinece. This normally works very well on russian-made devices. I'm not so sure about other manufacturers, but I suppose it just has a decreased likelyhood of success. It reminds me of the time I "fixed" an SG-11 by removing the faceplate and puting it back on. Stuff happens.

Heh-

The normal Russian approach to equipment maintenance:

If it doesn't work, hit it. If it still doesn't work, hit it harder. If it breaks when you hit it, it obviously wasn't built strong enough in the first place.

Reminds me of the movie "Armegeddon". Engines aren't working when they rather need to. Russian takes up a wrench. Says, "Thees *clang* is how *clang* we feex theeings *clang* in Russia *clang*" and the engines start up
