Audio controller malfunction - Seagate Barracuda 7200.7 ST380011A 80 GB Hard Drive

If the touch screen on your 2005 Jaguar X-Type is blank and you are receiving codes 50 and 51, it indicates that there is a communication error between the audio control module and the touch screen display.
Here are a few things you can check:

1. Wiring and connections: Check the wiring and connections leading to the touch screen display and the audio control module to make sure they are in good condition and properly connected. A loose or damaged wire can prevent the display from working correctly.
2. Audio control module: The audio control module is responsible for sending information to the touch screen display. If the module is malfunctioning or damaged, it can prevent the display from working properly. Check the module for any signs of damage or wear, and replace it if necessary.
3. Touch screen display: If the display itself is malfunctioning, it may need to be replaced. Check the display for any signs of damage or wear, and replace it if necessary.
4. Software update: There may be a software update available for the audio control module that can fix the communication issue. Check with a Jaguar dealership to see if there are any updates available for your vehicle.

“My Pioneer VSX 453 will not let me select alternate input sources..”Problem comes from front panel, switches, OR CPU switch control circuit via potential divider (matrix circuit).“ Is there a malfunction”Yes.

Does the system have an amplifier ?
Circuit/System Verification
Radio ON, Rear Seat Audio (RSA) OFF (if equipped), adjust the fade and balance controls on the radio to test all four channels individually. Each of the four channels should produce clear and even sound.
Without Amplifier Radio ON, verify clear audio is heard from each audio speaker.
?‡'
If audio is inoperative from all speakers, replace the radio.

?‡'
If audio is inoperative from one or more, but not all, speakers or the audio emitted from the speakers is not clear, refer to Speaker Circuit Malfunction - without Amplifier.
With Amplifier Radio ON, verify clear audio is heard from each audio speaker.
?‡'
If audio is inoperative from all speakers, refer to Amplifier Circuit Malfunction.

?‡'
If audio is inoperative from one or more, but not all, speakers or the audio emitted from the speakers is not clear, refer to Speaker Circuit Malfunction - with Amplifier.

Circuit/System Testing
Speaker Circuit Malfunction - without Amplifier

1. Ignition OFF, disconnect the harness connector at the appropriate speaker.
2. Radio ON, test for 5.0-7.5 volts between the signal circuit terminal A and ground.
?‡'
If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.



?‡'
If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.


3. Test for 5.0-7.5 volts between the signal circuit terminal B and ground.
?‡'
If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.



?‡'
If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.


4. If all circuits test normal, replace the speaker.

Contact a SONY service center. It is more likely that the hand held remote controller is defective though.

No, on the reset of controls.. There is probably a problem with the switches that are in the steering wheel.

You most likely have a defective Combination switch (Also known as "Spiral Cable" or "Clockspring") The audio system uses pins 14, 18, and 17 of the combination switch to make conmection to the audio system. Pin 17 is the reference voltage in. A failure here, will cause ALL audio controls to malfunction at the same time.
The cruise control uses Pins 19 & 20 of the combination switch....Totally different circuit. Just because this circuit is working, does not mean that the problem is not in the combination switch.

Assuming its a PC:- The problem may be due to the audio part. Try different music files or sound sources. - If the problem persists, on a windows system, go to Control Panel>Sounds and check & control the settings there. - If continues, try a headphone/earphone. If the audio is still not good on different audio sources, try reinstalling the sound drivers. If the audio is good, check the cabling and connections of the speakers (between speakers and PC, between two speakers and the power line) - If after all, the audio is still bad ( and headphone sound is good), the speakers have a malfunction. Try the nearest computer fixing service.

The headphones would not be the issue unless they came with an actual software cd included. If your audio Drivers are not the correct ones for your audio device on your computer, download the proper ones. Best way to find out what you have is to look under Device Manager which is in Control Panel, Under the System>Hardware Option in the Control Panel Folder.

Verify that your device is working properly. If it is working properly. and All other audio options, like Speakers work, then the Headphones are malfunctioning and you will need to contact the manufacturer.

If no audo works at all but the Device is listed as working properly, then you possibly have a damage audio jack port

This looks like the audio amplifier or the audio processing circuitry might be malfunctioning. To troubleshoot this you may have to use audio injection and detection to troubleshoot this problem. You would inject a known good audio signal and detect it throught the circuit. Since it looks like you are unable to control or have very little control over the audio. I would lean more towards the audio processing circuitry as being the problem. Thank you, Shuttle83

These items are not serviceable. If your are electrically minded you could try to find an alternative part But the norm is to replace the whole set up. Or download a suitable software to control through the pre-amp in the computer - www.audacity.com. RealTek97
