Test a PVS Screen with an External Power Supply
All PVS Screens
When troubleshooting a PVS screen that won’t power up, using an external 12 VDC power supply is the fastest way to
determine if the screen is working. The following procedure explains how to use the external power supply.
Use an External Power Supply
Use a separate 12 volt DC power supply (Fig. 1). The power supply from the E Series bikes, or TBT’s that have PVS will
work as well.
Fig. 1
1. Remove the back housing of the screen (Fig. 2) and disconnect the input AC power (Fig. 3).

Checking the Power Supply and Power Cables
E Series Treadmills
This document contains troubleshooting for both Version 1 and Version 2 MCB’s.
These procedures will require the motor shroud to be removed.
Warning: The following procedures require the power to be on. Take
extreme caution when working around live electrical components.
Version 1 MCB
If an embedded treadmill display will not power up, yet there appears to be power on the power supply, follow the steps
outlined in this document.
Tools Needed:
•Phillips screwdriver
•Multi-meter
•Small flathead screwdriver
Note: The procedures in this troubleshooting document require the power to be on and the drive motor shroud to be
removed. Take extreme caution when working around live electronic components.

Check the Power Supply
1. Check the power supply to see if the LED is lit (Fig. 1).
•If the LED is off, refer to document Checking the Power Supply (doc number: 637-1379) for
troubleshooting instructions.
•If the LED is on, continue on to step 2.
Fig. 1
2. Visually inspect the power cable connection at the power supply. Check for burned or charred marks on the
plastic connector (Fig. 2).
Fig. 2
•If there are burn marks on the connector, the cable must be replaced.
•If there are no burn marks on the connector, go to step 3.
Warning: The following procedures require the power to be on. Take
extreme caution when working around live electrical components.
3. Set the multi-meter to read DC voltage and take a reading between pins 1 (white) and 3 (black) (Fig. 3).The leads
must be in contact with the pin in the plastic connector to get a proper reading. There should be approximately 12
volts DC.

•If the voltage is between 10.5 and 10.9 volts leave the multi-meter leads in the plastic connector and continue
to Adjusting the Power Supply Potentiometer
•If the voltage is greater than 11 VDC, the power supply is sufficient.
Adjusting the Power Supply Potentiometer
1. Locate the potentiometer (pot) on the power supply (Fig. 6).
Fig. 6
2. Using the small flathead screwdriver, make small adjustments in the counter-clockwise direction and watch the
multi-meter. Turn the pot till the meter reads 11.2 volts.
