Hi guys, I've got an issue with my recently aquired TAF which I can't quite figure out. This is a 'normal' 1992 TAF which runs the LX3 Gold Roms (I purchased it this way).
When I open the coin door, the service buttons/volume buttons do not work. You can hear the noise/beep when you press them, but the display reads 'open coin door to use service buttons'.
My first guess was that there would be acid damage. I drilled out the backbox lock (keys were lost) and yes there are leaking batteries (batteries from June 2015), but it does not seem to have affected the board. I attached a photo of this. The battery holder will of course be removed asap.
Also, after removing the batteries and starting the machine (factory defaults) the coin door buttons work, once. I can change settings and save them as normal. After leaving the adjustmens/test menu's however, it's back to the 'open coin door' message (coin door buttons still generate a sound).
Now, I've checked for a coin door switch but this does not seem to be present in my 1992 TAF. So now I'm wondering, do perhaps the TAF Gold roms expect a coin door switch to be present and be activated for the service buttons to work? Do I need to install a jumper somewhere in order to fake this coin door switch?
All ideas are welcome. Thanks!
