It sounds like a bad solder connection. It just needs to be soldered up, if you take it into a shop just tell them it doesn't need any new parts, it just needs to be soldered up.
Or, if you can solder it yourself, or know someone that can, that would be much easier.
RCA Sub-Woofer
Did you try making sure the subwoofer is turned on under the set up menu on the Sony Receiver?
Press Set Up, Press the left or right button above the scroll wheel until you get to SW. It should say SW: ON or SW: OFF. If it says SW: OFF, use the Scroll wheel to scroll right until it says SW: ON. Also, make sure you aren't in 2CH mode, try A.F.D or surround sound.

Hi puntaloma
Your unit should hold settings for at least a week with the power off. Inside the unit is a backup power supply capacitor that maintains the preset memory. This part will be faulty and require replacement. It is not a user serviceable part, so if you wish to fix the problem, you will need to take it to a sony repair guy.

Reciever troubles
Slapping the unit causing the missing sound to come back tells me that there is something loose in the receiver. This could be a bad solder joint or dirty switch contact. Vibrations, such as sound, could be jarring the bad connection and causing the sound to cut out when it was just working a few seconds before. I don't believe you have a bad part in the receiver. When a solid state device fails, its gone for good. Again, it soulds like a bad connection. Finding a bad solder joint can sometimes be difficult. What you need to do is take the cover off so you can see the bottom of the PC board and using a good light source and magnifying glass, look for the bad connection. You can try running the receiver with the cover off and using a plastic pen, try pushing down on the PC board and see if you can make the sound cut out. You may be able to isolate the area by where you push on the board. Look for loose wires too. While you have the receiver open, buy some electrical contact cleaner in a spray. Radio Shack used to sell this as TV Tuner cleaner. I don't think they carry it anymore though. Spray the switches and rotate them back and forth several times. See if this resolves the problem. If you do find a bad solder joint, all you have to do is resolder it with some new solder. Make sure you do this with the power OFF. You're not looking at a big bill here. It's an easy fix once you find it.
Good Luck.

The display does not work on my Sony CDP-CE375 CD Player.
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.
My Sony model # MHC-V11 MAKES NO SOUND everything seems to operate but i cant get no sound from it
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.
My Sony DHC-FLX7D and DHC-FLX5D is not working due to humidity. Is it possible to repair it ?
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.
