With the board removed, turn it over so the side with keypad and LCD (front of board) is
visible. The fuse will be visible on the front. Location will vary with board version.

Replace fuses and reinsert board into the control panel lid. Board should be reinserted
by feeding the DB15 connector in first, then making sure the keyboard keys fit into the
controller lid. This is critical. Align screw holes on board with lugs on lid and loosely
tighten screws.
•
Reinsert the DB15 connector jack screws, taking care not to overtighten.
•
Tighten the four board screws.

Reinsert wires into terminal block. The correct wiring should be indicated on the top of
the board, but generally wires are in this order: red, black, white, purple.
•
With circuit board secured to lid, replace lid assembly on the control panel housing.

Replace housing screws. Connect to power and turn on. If fuse blows, consult
troubleshooting guide at the end of this manual.
Troubleshooting
While repairing circuit boards and other electronics yourself can be very rewarding, saving
both time and money, there are inherent risks involved. These risks include the risk of
electrocution, fire, burns, and damage to equipment. If you are uncomfortable or unsure of
your ability to successfully work on your TRC 1000, please contact us to schedule repairs. We
will be happy to fix your machine, or at least help you rule out any easy to fix issues (fuse
replacements and the like) before you send in for repairs.
For those who are comfortable working on modern electronics, the troubleshooting guide
below will help you resolve most common problems.
