DESCRIPTION
The console does not appear to power up.
SOLUTION
Use this instruction to troubleshoot the issue. NOTE: There are different instructions for treadmills
versus the other cardio products.
TOOLS REQUIRED
Phillips Screwdriver
Allen Wrench Set
Multi-Meter
PROCEDURE - Treadmills
1. Check that there is power to the outlet that the equipment is plugged into (verify by plugging in a
known working unit).
2. Verify that the power cord is securely plugged into the power receptacle and that the unit’s power
switch is in the on position.
3. Remove the 4 screws holding the rear cover to the console and remove the cover (Figures A & B).

4. There should be a red LED lit near J26 on the IO board (located near the bottom left hand corner of
the IO board – Figure C).
a. If the unit has a VA board installed, turn the unit power off and unplug the connector to the
VA board (labeled J1 on the IO board – Figure D). Wait for at least 30 seconds. Turn the
power to the unit back on and observe if the red LED comes on. If it does not, clip your
voltage meter clips onto the 2 outside posts of J1. You should see 12Vdc on the meter.
b. If this LED is lit, check to see if the switch on the IO board is in the correct position (Left –
EX Power for units with a DCI MCB and Daughter Board, Right – LCB Power for units with
a Delta MCB). If unsure which MCB is installed, it is worth the time to toggle the switch to
ensure it is in the proper position. If the LED is lit and the switch is verified to be in the
correct position, replace the console.
c. If this LED is not lit, unplug the J26 power connector (this is a flat black 8 pin connector)
and reconnect it to verify that the connector is seated properly. If this does not resolve the
issue, continue to Step 5.

5a. DCI MCB Treadmills (see Step 5b for Delta MCB treadmills):
a. Remove the motor cover and determine if there is power to the MCB. There should be various LEDs
blinking on and off (Figure E). After checking if there are LEDs lit power off the treadmill.
b. Locate the power supply board and check that there are 2 different connectors plugged into this board
(Figure F). Unplug the connector on the 12V supply side (connector 2 in Figure E). Clip your
voltage meter clips onto the 2 outside posts and turn the treadmill back on. You should see 12Vdc on
the meter. If not the power supply board and components should be replaced (power cord, receptacle,
switch, and wiring).

5b. Delta MCB Treadmills (see Step 5a for DCI MCB treadmills):
a. Remove the motor cover and determine if there is power to the MCB. There should be an LED lit
that is on the upper left hand corner of the MCB that is labeled 12V (Figure G). If this LED is not lit,
check the power components (power cord, receptacle, switch, and wiring), if all seem good, replace
the MCB. After checking if the LED is lit power off the treadmill.
b. Unplug connector J10 on the MCB. Clip your voltage meter probes onto the outside pins of the
connector on the board. Turn the treadmill back on and verify that 12V are present. If the voltage is
not correct, replace the MCB.

1. Check that there is power to the outlet that the equipment is plugged into (verify by plugging in a
known working unit).
2. Verify that the power cord is securely plugged into the power receptacle and that the unit’s power
switch is in the on position.
3. Remove the side covers so that the LCB is visible and accessible. On most Matrix cardio units, it is
recommended that the right side cover be removed as this will give the best access to the LCB.
4. Check the sticker on the LCB and determine if the board is labeled LCB3 (Figure H). If the board is
not labeled, it should be LCB2 (Figure I). If the board is labeled LCB3, skip to Step 5b. If the board
is determined to be LCB2, continue to Step 5a.

5a. LCB2 - Verify that there are LEDs on or blinking on the LCB. If there are no LEDs lit, replace the
power components (power cord, receptacle, switch, and wiring). If there are LEDs lit, turn off
power to the unit.
a. Unplug connector J9 from the board (this is a flat black 8 pin connector). Clip your voltage
meter probes onto the outside pins of the connector on the board. Turn the unit back on and
verify that 12V are present. If the voltage is not correct, replace the LCB.

power to the unit.
a. Unplug connector J4 (also marked Console) from the board (this is a flat black 8 pin
connector). Next to this connector on the board are 2 non-filled spots labeled GND and 12V.
Clip your voltage meter probes onto the GND and 12V prongs. Turn the unit back on and
verify that 12Vdc are present across these 2 points. If the voltage is not correct, replace the
LCB.
