Hi, I am seeking advice from a kind expert to help resolve problems with my TAF pinball, I am in the UK on 240V AC domestic circuits, summary of my issues as follows:-
S.
- The WPC Power Board is dated March 1992, all fuses check ok when removed, all LEDs are correctly illuminated
- The game runs ok some of the time, everything works correctly apart from the Thing magnet which won't pick up the ball or power up on test mode.
- On occasions when switching on the table a circuit breaker trips in my consumer unit, 230V measured in the line input box inside the cabinet (maybe just the power demand from the table).
- TAF often loses GI and Solenoid power during games, sometimes it starts up with no power to the GI or solenoids but the DMC and sound do work all the time. When the power to the play deck goes it can stay off for some time or come back again quickly.
- When the lights go out Relay 1 on the power board starts clicking, it is normally quiet, I have the Fliptronic board in the cabinet and from what I have read online the relay serves no purpose. There seems to be a link between the clicking Relay and the power drop.
- The table has the original GI lighting, no LEDs installed, the PCBs are originals other than a Rottendog DMC controller I just installed as there were signs of overheating on the original DMC board. I also installed a new Opto board for Thing but again the power problems were there before and after I changed these 2 boards
- Also the thing magnet has no power, when running the solenoid test all the pins on J130 show 77.5V DC against the ground test pin except pin 7 (violet-blue wire) which is 0V, this is the pin for the Thing magnet. The wires to the Thing magnet from the backboard check out ok. I have attached some pics of the power board in this area
- When the thing hand moves it triggers both the Thing up and Thing down Optos on test mode
- There are no visual sign of any damaged connectors, wires, pins or sockets.
- Resistance across the solenoid coil for the thing magnet measures 68 ohms with a DMM
- There is some sign of aging on the power board, see photos. Near R202 / R205 the soldering in this area seems degraded or maybe signs of a previous repair
