I had the same problem, static but no sound. I took the TV apart and vacuumed all dust from it. There was some pretty heavy dust in there. Once I put it back together and turned on, all worked great.

Unplug the tv set for 30 seconds, plug back in and turn set on. if this does not return your audio you need and you're NOT still under warrantee you should at least open the TV and check the board where the components are mounted and resoled any that look bad. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint. All can be replaced at a local electronic or hardware store and they're easy to replace good luck

No Sound - Very quiet static/ticking noise

http://ca.asus.com/en/Motherboards/Intel_Socket_1366/SABERTOOTH_X58/

Specifications;

Audio: Absolute Pitch 192kHZ/ 24-bit True BD Lossless Sound
- Asus noise filter
- Optical S/PDIF out port/s at back panel

http://www.asus.com/News/8krSWx1MniBbcCUI/

Ummm,....No.

10 Channel sound (?)
BD stands for Blu-ray Discs
192kHZ/24-bits True BD

The above is a 192kHZ sampling rate with a 24-bit sound output.
REALLY good quality.

However,

Realtek ALC892 is the audio chipset.

http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PNid=24&PFid=28&Level=5&Conn=4&ProdID=284

"The ALC892 provides ten DAC channels that simultaneously support 7.1 channel sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs."

Oh, 10 DAC channels.

Hello, My samsung ln82341w has sound problems. Two cable channels have no sound; 1 channel has crackling/static sound; and most of the other channels the sound will go out when the first one or two...

The problem isn't with your TV, its with the cable company.
Call the cable company, problem is most likely with your digital box or a signal problem.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

It is an old speaker (DM601 S2) but well cared for. Have clear sound in one speaker and static in the other.

It sounds like a ground problem with the speaker crossover circuit or the amplifier. Turn the amp off and disconnect one speaker and interchange it with the other using the same speaker wires. If the static speaker is now working interchange the speaker wires and try it again. Or if the same speaker still has static it is the speaker. If the static is on the same channel then you have a bad wire or if both channels work it was a bad connection. If the problem remains on the same channel change the speaker wires. If the problem switched to the other channel then it is a bad speaker wire or connection. If the same speaker has the same problem it is most likely the crossover circuit in the speaker which is used to filter frequencies of the audio signal by using capacitors and coils. If the static speaker is now working and the other speaker is now not working it is the amplifier. If the static problem is on all input devices I would trouble shoot the preamp section of the amplifier.

When using cable input video is good but sound has fuzzy static

Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

Can't get sound off my right speaker,,brand new cartridge, checked wires with VOM everything looks ok but no sound..I'm stuck

Is the amplifer working OK? Go to the phono input and put your finger on the right channel. It should hum. if it does not, you might have lost the internal preamp for cartridges. If it does hum then you need to recheck the right channel wires, conections etc. Don't forget you can change the conections over and see if the left channel will come on the right side.
If it is the preamp you might find an IC is the cause. Often these devices here are static sensetive.

Please explain the working of this code

It's a Java http server (webserver) that serves random "prices" if they match a search string.

Well here is an explaination:

private static String[] symbols = {"DELL", "INTC", "MSFT", "ORCL", "SUNW"};
These are search strings

private static Random rnd = new Random();
This generates a random number

private static Charset cs = Charset.forName("UTF-8");
This is the charset that the http server uses

ServerSocketChannel server = ServerSocketChannel.open();
Create a new server

server.socket().bind(new InetSocketAddress(8055));
Bind the http server to port 8055

The rest is handling the request and processing it

But here:
if(Arrays.binarySearch(symbols, symbol) >= 0)
response = "Price is " + (1000 + rnd.nextInt(9000)) / 100.0;
else
response = "Price not available";
channel.write(cs.encode("HTTP/1.0 200 OK "));
channel.write(cs.encode("Content-type: text/plain "));
channel.write(cs.encode(response));
channel.close();
}
It sees if the string input matchs: DELL INTC MSFT ORCL SUNW.

(private static String[] symbols = {"DELL", "INTC", "MSFT", "ORCL", "SUNW"};)
If so, it gives a price based on a random number.
(
response = "Price is " + (1000 + rnd.nextInt(9000)) / 100.0;)
Or else
It says "price not available"
then it gives a html header to end the error message.

Hope I helped you :)
Gook luck
