Quoted from alexanr1:Thanks everyone. I will double check battery corrosion. IPAs far a rubbing alcohol, I believe all it may be doing is creating a circuit thru the alcohol. Not sure that will long term fix anything. Willing to give it a try.....
Troubleshooting this problem seems more complicated than other issues I have had with other machines. Narrowing it down to a specific connector is what seems messy.
Alex, I have had all kinds of problems with my TZ from the locked on flasher mentioned above to everything else. Out of the 20 games in my collection TZ is probably the one game I am always fixing. I don't know if this was covered in any of the other posts but since you changed the 6 or 7 ribbon cables in this game, make sure you are not off with the pins and the connectors. I know when I changed or remove the ribbon cables, it seems like I either miss one pin or possibly a whole row when reinstalling the cables. That can cause weird things to happen if you are not dead on with the ribbon cables and the pins on the board. I have done it many times even after double checking before turning on the game. Sometimes my TZ will go into a reboot of sorts and never get to the game play. Reseating the cables usually fixes the issue. Also pull the IDC connectors on and off the playfield again to make sure you dont have a bad connection there also. I had to do that many times as well. I needed to change burnt connectors at times and change out blown fuses. I just had the left magnet stop working on my TZ. Turns out i needed to reseat the two wires coming from the magnet to the board under the playfield (Top left corner of playfield) in order to get the magnet working again. Had to punch down the wires with my punch down tool into the connector and reseat. Always something with this game it seems. Thank god I can fix my own games because this game would have cost me a fortune with repairs. Good Luck
