LS RNS - Dead - No Functions

Ford Repair Service:
LSRNS System Startup Failure

There is a fairly common hardware problem with this generation of Ford Radios made by Blaupunkt and FoMoCo as shown here, where the stereo fails to boot up or switch on correctly.





There appears to be a common fault where the system will not switch on, giving nothing more than a black screen, and gives the initial appearance of being totally dead. If there is a disc currently inside, then it may be heard to spin for a few seconds, although it will not eject. Whilst the radio is in this state, it is not unusual to experience a current drain on the vehicle of approaching 1A which is sufficient to flatten the car battery if left for any period of time.

We have seen this fault appear after a jump start or battery disconnection, and is very common if you have downloaded some pirate software from the internet in an attempt to upgrade the software, but that said, we have also seen the fault appear from normal useage as well. If disconnected, the reboot that follows may not allow you to get as far as the code entry screen, with the unit simply showing a black display.

This fixed price repair is for the system boot up fault as described only, if any other faults are found, or the unit has been tampered with, then we reserve the right to provide an estimate for any additional work that may be required.

Whilst we will try our utmost to preserve any data on your unit, in some instances we may need to return the unit back to its factory default setting. We are unable to provide or upgrade any mapping data and you may need to reload and activate your original mapping software.

When sending your unit to us, do not forget to enclose your code number. If a code number is not provided, then an additional decoding charge will apply to cover the cost of code retrieval - full details of our decoding costs can be found on our website under the relevant section.
