The Simpsons Beer Guide not fully powering up

Recommended Posts

The left hold button seems to be faulty though as it's not responding when pressed for holds or nudges.

Nice work, I was hoping that would be ok. That's a result being a good board in there. You really need to desolder the battery and neutralise the area or it will destroy it in no time. If you do there's no reason it won't keep running for years.

Andrew might be able to help but I think the vsync in the power supply that was missing helps to sync the all boards on whatever hertz range it runs at through the power loom rather than the serial cable. Thats the best I can come up with so far 🙂

For the button check the wiring your looking at the inner switch wiring and you can compare it to the next button. The outter two wires are for the lamp in the button and not important.. Also check the next button is correctly wired too. If it's all ok I'll tell you where to look next 😎

Hold button was a loose connection into the hole so the outer button wasnt making contact with the wee black button. Also one of the spade connectors was off so put back in and light working now. :)

I have a few bulbs out so will sort that but another issue seems to be the coin mechanism as it's not recognising 5p and 10p coins. It still only accepts old £1 coins so wondering if I should just update it and sort the issue at the same time?

Make sure the machine is turned off when you replace the dead bulbs. You might end up damaging your lamp driver board otherwise....

Lots machines don’t accept 5p’s.

 

and are you trying old 10ps? Or the newer ones?

Definitely the newer ones, it's hit and miss whether it accepts them. Old £1 coins, 50p & 20p coins are fine. 

I've found a guy who's not far away from me to get the coin mech updated to the new £1 coins. Going to do that, replace the bulbs and then find someone who can solder so I can get the MPU battery fly connected to further it's lifespan. 

Cheers for all the help so far guys.

The Epoch main board is the heart of that machine and will be a ballache to replace so here's a few more tips-

Keep it in an antistatic bag if your transporting it.

Keep it dark- the game data on the Eproms is erasable by UV light so keep it out of sunlight 

The alkaline battery leakage needs neutralizing or it will keep eating away for years. An epoch board can fit in a small container flat and you can tip some IP-alchol on it and leave it partially submerged for 10-15 mins. That will get under everything and kill off most of the rot on contact. Leave it for a good 12hours to dry somewhere safe. Check it now and again in the future. You can do this as many times as you like.

If you do all that with minimal tampering afterwards it should run for years 😎

People tend to neglect them and get highly frustrated when they stop working so look after it.
