Was working just fine. Now low audio even with it turned up all the way.
I connected pc speakers to the audio out rca jacks and that works.
All inputs have low audio output.
There also seems to be slight "moire" swirl lines on the screen now too.

Unless the set has actual audio outputs it should not be done.
The set will have a very low audio output not intended for external systems--if you hook to wrong impedance speakers volume either will not work, be very low or even damage the audio circuit in the set
First try hooking up a different source such as a DVD player or Cable box and see if you have audio. If you do then check the audio output from the computer. If you do not have audio then make sure the tv audio is up half way and turn off the set. When you do this you should hear the down chime provided you have the chime turned "on". If you do not hear the down or up chime then the sudio circuits on the Main bd are bad and the Main bd will have to be replaced. A quick way to check to see if the audio circuits are working is to listen for the up or down chime when turning on of off the set coming from the tv speakers speakers.
I wasn't able to lookup a manual for the Sharp GB960. In fact, manuals for any Sharp car audio product was woefully absent.
Try connecting the cables to the input of an amplifier. Female RCA jacks are used for low-level (preamplifier) outputs for subwoofers, sound processors, and additional amps. The impedance of the output is typically in the 20-25Kohm range and would not produce any sound in speakers or even low impedance headphones.
It's also possible that the RCA cables are an "AUX" input to the receiver and not an output. Although many of the mobile audio manufacturers are now using front-mounted phone mini-jacks as "AUX" inputs, some still have rear mounted RCA's.
are you using RCA outputs(the round red and white plugs)? if you are then your amp is not turning on and if you are hooking up speakers to your RCA's (low level) then you will not hear any audio the signal is to low. would need to know more about how you checked the ic power?? one could verify an output ic by hooking up an amp since the RCA audio signal is picked off just before the output. if the low level works but the speakers do not then you have a bad output. anything else an o-scope would be handy.
