Hi. I decided to finally replace the bulbs on my machine which don't work. Turns out the bulbs are ok, I've also swapped entire light socket and diode over to be sure it wasn't faulty sockets/diodes. On the right of machine,the whole entire right of playing field (target line) don't light...

Thanks for the quick response! I have not even checked up the top.. im a bit amazed the tube light still works! the machine is actually not in too bad condition considering it was left in a damp cold warehouse for about 10 years.. i guess. i see there are rebuild kits available from...

Hi, I removed the board from the machine and it looks preety clean, not any visible corrosion on it, from what i can tell the speaker plugs directly into the board, i was thinking there was an external board amp, but now realise its all on the game board. do you think its the game sound chips or...
