Issue:
Customer failure mode is an intermittent 1-2s loss of audio in any source, which then recovers but can happen multiple times.
The occurrences may vary depending on location and proximity to transmitters in the UK.
Cause:
The issue first occurred on Wednesday 28th August and corresponds with a change in the UK Broadcast for TV Electronic Programme Guide (EPG) feature.
This issue appears only to affect vehicles fitted with the Lear Hybrid TV module.
The broadcast causes the TV module to carry out a reset which results in a temporary loss in audio, irrespective of which audio function is being used e.g. (Radio, CD, etc).
Action:
As a temporary measure and with customer approval it is possible to mask this drop out by setting the TV region to USA. However, this does prevent the TV from operating but provides a quick although temporary fix until a more permanent resolution can be found.
1. No parts are to be changed in an attempt to resolve this issue.
2. Disable TV by selecting USA region from the touchscreen
3. It is essential to perform a successful shut down of thevehicle electrical system, by ensuring the ignition system is off and not used for a minimum of 5 minutes. This ensures the TV records this as a 'last good state' and that the new region is stored when the vehicle is powered on.
4. This is a temporary solution until permanent fix can be established. JLR will communicate this permanent fix as soon as possible.
