It seems that the main sound processor comes into an error and so seems a fault on the board. Since checking for a component level solution is very tricky as the access is not friendly, what could be done initially is to remove and reset the boards, check for faulty connectors that seems to vibrate and bring in these faults. Check the solde joints of the connector pins on the board. Check and solder the processor IC and the allied circuits. If the fault seems to disappear when the set heats up then you must check using a magnifier.Check the solder on the audio driver outputs of the center, main , front and rear are clean.
If not refer and proceed with consensus as a false move can cripple the set.

How can i connect a dvd player to the LG sound bar


On the back of the DVD player you will find a Red and a White RCA plugs and the video out plugs as well, The Red and the White RCA plugs are the Left and the Right Channel Audio out from the DVD player, Using a RCA cable set connect that to the sound bar. If you don't have the audio cables you can get them at Radio Shack or on eBay for cheap.

Yes , the possible fault can be a suspected fault in the sub woofer power amplifier. You will need to remove to check the circuit.
It can be a faulty or dry soldering in the main board., re solder IC.
Also if the IC is faulty it can be erratic, a signal test must prove it right applied to the input.

I have bought an used Nakamichi AV1. The unit powers up and the display is fine. The problem is that there is no sound output from any source (Tuner, CD, Phono or tapes) to the speakers. I get speaker...


From the initial posting of this question. (Please only update one.)

There is a switching IC inside this unit that may be the problem, but without seeing the actual unit and signal tracing, this will be near impossible to diagnose. If you have an oscilloscope, place an input signal on one of the inputs and trace the signal to the IC. It will be a TA9263 or something similar. You should see the signal on 2,4 or 6 pins. If you see the signal only on 2, then the IC is likely to be defective.

That would be my first attempt. Also check the power supply to that IC.

Keep us posted on progress.

Thanks,
Dan

I HAVE ONE AIWA CXNS32HR ,NOW I AM FACING SOME PROBLEM WITH THIS SYSTEM ITS DISPLAY IS SHOWING STANDBY AND SELF DEMONSTRATION NO OTHER FUNCTIONS ARE WORKING, ANYBODY CAN HELP ME


you should check the voltage of "O-POWER" on main board (PCB Front and side), and stress "STD-BY" there should be 5 volts when the power button is turned on. if no response, the damage was in power system regulators or the EEPROM IC with the code "D780228GF" or D780226GF ". you have to replace the IC or other parts in the regulator. transistors and diodes.

Sounds like a loose connection. What audio source are you using? If you switch sources, does the other source have the same problem?

I have no sound with my lg blue ray player but my lg dvd player has sound throught and i am using a hdmi cable and i have set the blue ray audio settings with a lg tech anything will help thankyou


Some times the DVD player needs to be set to output digital audio through HDMI. If that is set, then do the same with the menu options on the TV/LCD/Plasma/Screen that you are using.

Denon AVR-2309C1 will not play sound through


Turn off zone 2 then turn your receiver on the main zone on Radio, tune in a station and check for audio. Post a comment and let me know if audio works that way. If you don't have any audio, list your other equipment makes and models as well as how they are interconnected to your receiver (cable type) and I will help you troubleshoot

I have tuned in my video to my tv but I cannot get the tv station


I had a similar problem. After a nearby lightning strike I lost video to the TV. When the SA-HE100 source switch was set to DVD or TV I lost the TV picture. In my system configuration I send composite video (yellow jacks) to the SA-HE100 from the DVD player, VCR and satellite receiver. From the "TV Monitor Out" jack (yellow jack) the video goes to an RF modulator then is sent to the TV as RF channel 3. At first it seemed the modulator was defective but plugging in another identical modulator damaged the second unit also. This made me look at the amp as the culprit. Curiously, the amp would pass through VCR video without a problem but I didn't know it because of the damaged RF modulator. Whenever the amp source switch was set to DVD or TV the amp would put -4.75V DC on the "TV Monitor Out" jack thereby damaging the connected RF modulator. The repair is relatively simple. The only special skill required is you will need to be able to desolder a 14 pin DIP IC. The damaged component on my amp was IC364 mounted on the board that holds the yellow video jacks. The IC is a JRC 2279D, a 3 input/2 output video switch available from Digikey p/n NJM2279D-ND, $1.50 each.
