GENERAL GUIDE FOR REPAIRING ANTAR PINBALL

The modular system designed for that machine allows the replacement or repair of any faulty unit in a very short time because the modules con be replaced on the spot, where the machine is located, by a new one, whenever the failure is of electronic origin. To this end, all modules are of a reduced shape in order to facilitate the repair or its transportation when necessary. For this purpose there are cases with a complete set of modules as well as the necessary tools to substitute them.In order to know which are the modules to be substituted it is important to follow these general guides:

IMPORTANT ! TURN OFF POWER BEFORE REMOVING OR REPLACING ANY OF THE BOARDS.

  1. The light box display, the lights controlled and the flippers do not work. ... Substitute, following the same order, until the failure is found: PSU (checking the fuses), MPU, IOS.
  2. No one display lits but some controlled light lits permanently. ... Substitute, following the same order, until the failure is found: PSU, (checking the fuses), MPU, IOS.
  3. No one display lits but some controlled lights lit alternatively. ... Substitute, following the same order, until the failure is found: DPY first player, IOS.
  4. The display of one or several players lits, changing from 000000 to 999999, but not all. ... Substitute, following the same order, until the failure is found: DPY first player, DPY second player, DPY third player, DPY fourth player DPY STATUS.
  5. The sound fails.... Substitute, following the same order, until the failure is found: IOS, loudspeaker.
  6. Some of the controlled lights never lits.... Substitute, following the same order, until the failure is found: LIGHTS FUSES, LITTLE LAMP, the corresponding BLC (see the number of the little lamps or change the three BLC). Note that the bumper lights have a rec-tifier in the playfield.
  7. Some controlled little lamp, other than GAME OVER or HIGH SCORE, is al-ways lit.... Substitute, following the same orden, until the failure is found: Corres-ponding BLC (see little lamps numbers) or change the three BLC successively.
  8. Some memorized drop-target solenoid does not work.... Substitute, following the same order, until the failure is found: BTC, IOS.
  9. Bumpers, flippers, kickers, ball return, guns, "taca".... Substitute, following the same order, until the failure is found: First check whether the corresponding relay closes properly, if not change: BSC, IOS.
