Only solution go back for warranty if there is no answer for this solution in the user manual. release power connector for a moment isnt the right thing tom do , this product is to young for any kind of problems, the hum is look like there is a capacitor damaged or something loose in the power supply that there failed a powerline , the only thing is back to the dealer for warranty.

Sounds like a problem in the amp section.

Overheating?

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

The main power supply filter capacitor is the problem, as the temperature rises the capacitance drops while in use and eventually the audio gets a distinctive 60 cylce audio hum. The part must be replaced in order to correct the issue.

Are you sure that's what it is? Something is heating up for sure.

It could be protecting itself because something in the volume control is going bad and sending too much current through the amp or any other reason. In other words, you can guess and buy parts hoping to nail the symptom but not knowing the cause, or you could let a technician do it.

You may need to enter the setup menu on the PS3 and enable the decoding for blu-ray discs.

That points pretty much to a bad shield on the cable. Have you tried another one? Another thing to try is to rotate the AC power cord on the sub (if it has one). Sorry, too lazy to look it up.

Best Answer - Chosen by Voters An ohm is a unit of electrical resistance. You can think of it as your speaker will impede or pull 8 ohms from the amplifier that is powering it.

8 ohms is less resistance than 4ohms. So a 4 ohm speaker would require more juice than your 8 ohm.

If this is the only speaker, then that's all the resistance you have to worry about handling. If you had two of these speakers wired in parallel, then the total impedence would be up to be 4 ohms, because each speaker actually reduces the resistance in the circuit...so 8 ohms + 8 ohms = 4 ohms.

You use this information to make sure your amplifier is powerful enough for the speakers. If the speakers have too much resistance, they'll fry your amp.

Here's a good sentence to help explain, but I recommend reading the article I linked in sources...

"An amplifier designed to put out 100 watts into 8 ohms will put out 200 watts into 4 ohms. Two 8 ohms speakers wired in parallel (4 ohms total) would cause the amplifer to produce 200 watts." Source(s): http://www.marktaw.com/recording/Electro…

Hi David, do you want to connect the ST-D505 tuner to the TA-D505 amplifier? You just have to connect an audio cable of two RCA (red and white) from the audio output L and R of the tuner ST-D505 to the input of Tuner in the amplifier TA-D505 Remember to connect the FM antennas and the AM Antenna Loop on the ST-D505 tuner To listen to it, you have to select Tuner on the TA-D505 and enjoy the favorite radio stations I hope you have my comments Greetings Franco Dosil Hola David, quieres conectar el sintonizador ST-D505 al amplificador TA-D505? Simplemente tienes que conectar un cable de audio de dos RCA(rojo y blanco) desde la salida de audio L y R del sintonizador ST-D505 a la entrada de Tuner en el amplificador TA-D505 Recuerda conectar las antenas de FM y la Loop Antena de AM en el sintonizador ST-D505 Para poder escucharlo, tienes que seleccionar Tuner en el TA-D505 y disfrutaras de las estaciones de radio preferidas Espero que te sirvan mis comentarios Saludos Franco Dosil https://elektrotanya.com/sony_lbt-d505_d505cd_d505cdm_d505m.pdf/download.html

troubleshoot the issue: Reset the CD Changer: Turn off the CD player. Press the CLEAR button. Simultaneously, press and hold down the POWER button on the CD player for 60 seconds. If this doesn't resolve the issue, proceed to the next step. Check for Error Messages: If you encounter difficulty playing a disc and receive any of the following error messages, there may be an incorrect setting or a problem with the disc: NO DISC DISC ERROR CD ERROR TOC ERROR Refer to the instructions supplied with your CD player to verify model-specific information and troubleshoot the issue. Internal Component Repair: If the display issue persists, it might be related to an internal component that requires repair.

Troubleshoot this issue. Here are some steps you can follow: Check Speaker Connections: Ensure that the rear surround speakers are properly connected to the Audio/Video (A/V) receiver. If applicable to your model, verify that the A/B speaker selector is set correctly. If the speakers are connected to the A speaker connection, the selector must be set to the A position. Test Tone Operation: Perform a test tone operation to check if the speakers are functioning correctly. Increase the rear speaker volume or adjust the surround speaker settings to the maximum level. Speaker Size Settings: Try selecting a different size (small or large) for the rear surround speakers in the menu. Surround Sound Mode: Verify that the A/V receiver is set to a surround sound mode. For Dolby ProLogic surround sound, ensure that the center-channel mode is set to NORMAL or WIDE. If your source is a DVD or Blu-ray Disc player, check that surround sound is enabled in the player's menu. The audio being received must be multi-channel. Different Surround Sound Mode: Try setting the A/V receiver to a different surround sound mode. Source Content: Verify that the source you are playing is encoded in surround sound. Note that during periods of mainly dialog, most of the sound may come from the center speaker only, with audio coming out of the rear speakers when there is background or ambient noise. Factory Reset: Reset the unit back to factory default settings (consult your operating instructions for model-specific steps). If applicable, follow the steps for calibrating the appropriate settings automatically after connecting the calibration microphone device. Speaker Wires and Replacement: Check and replace the speaker wires if necessary. Consider connecting a different pair of speakers to see if the issue persists. If you've tried these steps and the problem remains unresolved, I recommend seeking professional service.

steps to troubleshoot and potentially repair them: Troubleshooting Low Sound or No Audio from Rear Surround Sound Speakers: If you're facing audio problems, especially with the rear surround sound speakers, consider checking the following: Ensure that all speaker connections are secure and properly plugged in. Verify that the speaker wires are not damaged or frayed. Check the speaker settings in the system menu to ensure correct configuration. Inspect the speaker impedance and compatibility with the system. If you're using wireless speakers, check their power supply and connectivity. Refer to the operating instructions manual for specific troubleshooting steps. Flexible Circuit Board Repairing: If the issue is related to internal components, you might need professional repair. However, if you're comfortable with electronics, consider these precautions: Keep the soldering iron temperature around 270°C during repairs. Avoid touching the soldering iron on the same conductor of the circuit board more than three times. Be gentle when soldering or unsoldering to prevent damage to the conductor. Important Notice: To prevent fire or shock hazard, avoid exposing the unit to rain or moisture. Do not open the cabinet; refer servicing to qualified personnel. Avoid installing the appliance in confined spaces like bookcases or built-in cabinets.
