Determining the PVS Screen Type

There are times that it is important to know the type of PVS screen in order to properly troubleshoot an issue. There are
two types.

• UTI screens will have the label on the upper right corner of the screen (Fig. 1 and 2).

• Tatung screens will have the label towards the left center of the screen (Fig. 3 and 4)

To determine the screen type, remove the plastic back cover of the screen and look for the label.

PVS Testing with External Power

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.

Page 4

637-1401 Rev. B

Service Bulletin

Warning: the following procedure requires the power to be on.

Please exercise caution when working around live electrical components

Use an External Power Supply

Use a separate 12 volt DC power supply (Fig. 5). The power supply from the E Series bikes, or TBT’s
that have PVS will work as well.

Fig. 5

1. Remove the back housing of the screen (Fig. 6) and disconnect the input AC power (Fig. 7).

2. Insert the external power supply into the back of the screen (Fig. 8) and plug it into the wall (Fig. 9).
