My sound system isn't working - Compaq FP 5017 15" Flat Panel LCD Monitor

Make sure the system volume is up, the TV isn't muted, and the sound cables are completely in their sockets on the TV. If none of that works, the sound card may not have its drivers, or is bad.

check in your control panel and go to systems.
Then go to hardware and under that go to Device Manager
In there see if there are any exclamation marks in your sound hardware,
conflicts and such.
If there are none then go to Sound Controls in Audio Devices and make sure the audio isn't muted in the windows program
Use this to do an audio test of your speakers.
If that isn't working but it should be check your wires to see if there is a break or if it is plugged into the the green colored jack for external speakers.

no coolant problem will cause a heat problem sounds like you have a low freon charge in the ac system if empty the system hold 1.5 pounds of freon

Does the set have sound with a DVD etc. directly connected to one of the audio/video inputs this set has?

hi, check yr sound driver in system properties, look at your sound driver, if have yellow exclamation mark that mean your need to reinstall yr sound driver,
if not try use external speakers and see what result
TQ

I do not have a manul to tell me how to set the speaker sound in each speaker

Make sure the computer volume itself isn't muted and is not set really low. Check to see you actually have sound drivers installed and the right output selected.

You will need the condenser coils repaired before you can charge it. These come from the factory sealed and they should not ever need a charge unless you have a leak. The hissing sound is more likely air in the system being pumped by the comressor and it is coming out a hole in the coils.

The Bravada AWD system works with imput from the ABS wheel sensors. Sounds like the sensor in the hub you replaced isn't sending a proper signal. You must correct this for the system to work right. Check to see if the ABS connector is fully engaged, and check the wire to make sure it isn't cut.
If any thing dosen't appear wrong, it may be the sensor that's failed.

Check the compressor to see if it is running. Is it too hot to touch. If so make sure the condensor has proper air circulation to cool it. If the compressor is cool to touch and running. There is a leak in the refrigerant sealed system.The compressor isn`t doing any work because there isn`t any refrigerant in it, therefore will not creat much heat. A humming and clicking sound is typical of an overheated or damaged compressor. If the compressor isn`t running and connot start. It could be a bad start relay on the side of the compressor or a bad compressor. If you can remove the start relay, shake it and listen for a rattle sound. If it rattles, it is bad.If not. then it is time consider the cost of a repairman verses the value of the appliance. Check the cost of repair to the sealed system or maybe even replacing the compressor.I hope I have been of some help to you.
