Radio Tuner Display And Backlight Has Intermittent Failure (TS 02 06111)

RADIO TUNER DISPLAY AND BACKLIGHT HAS INTERMITTENT FAILURE

TECHNICAL SERVICE BULLETIN

CONDITION

The radio display and/or backlighting will blink on and off intermittently, or fails completely.

CAUSE

The front lower portion of the tuner frame backing plate becomes bent during the removal of the radio and will not allow the faceplate connectors to seat properly.

CORRECTION

DO NOT replace the Radio Tuner assembly! Please take care not to bend the frame if it is necessary to remove the radio to make repairs to the vehicle. If you encounter a vehicle that is experiencing the condition, refer to the example shown in this bulletin and inspect the tuner frame. If the frame is bent, restore the bent portion to its original position so when the faceplate is attached, the connectors will seat properly.

1. During the radio tuner removal process, while separating the clips that secure the tuner to the dash mounting, there is a risk of bending the sheet metal frame acting as the backing-plate for the radio display panel.
2. Perform a visual inspection of the backing-plate portion of the frame, use a straight edge or similar reference if there is any doubt the sheet metal surface is bent.
3. When the backing-plate is bent it can prevent the connectors of the face-plate and the tuner body from seating correctly causing the failure. When testing a unit with a display that is not working, apply light pressure against the display at the two points where the connectors are directly behind and see if the display begins to operate. This is an easy way to confirm that the frame may be bent prior to removing the tuner assembly.
