Replacing Playback Key Caps on Ti

Determine Version of Playback Circuit Board

The replacement key caps are different based on the revision of the circuit board installed in the console. Unfortunately, key caps are not interchangeable between the two versions so it is important to know which version to order.

Step 1: Power down the console
Step 2: Unplug the console from mains power
Step 3: Lower the display panel completely.
Step 4: Open the face panel by turning the 2 locks on the bottom of the chassis.


Step 5: Examine the color of the circuit board of the Playback buttons. It will either be black or blue.
Step 6: Lower the console face panel and lock it closed.

Parts to Order

  • You will need to order part 4350K1009 Ti Enhanced Cherry Playback PCBs Kit as the individual key caps are no longer available for replacement.
