press SET UP :select NORM.SP then is select LARGE .that should do it

check your main board witch is under the powersupply. careful the caps hold charge and hurt really bad. check your digtal input board also.

This unit is having a problem with the preamplifier and power amplifier section. The reason to suspect this is that you can still hear sound, this is not likely if you ahd a failure in the power supply section. The unit may have had a failure in the amplifier areas of these sections, These are the signal amplifier sections that increase the power of the signal to drive the sound in the speakers .The Unit is probably in the protection mode reducing all power to prevent further damage to the rest of the receiver. You can go to the www.sony.com website support section and look in the frequently asked question and troubleshooting sections for problems like yours and see if they have any answers. On this website you can also find customer support. Ask them questions about the problem and see if they have any solutions.If all this fails to answer you problem, you can try opening the unit and looking for the problem yourself. Only work on the unit with it unpluged from the power source. Take off the top cover and look for any damaged areas, on the pc boards.They would be brown areas from excessive heat due to component overheating and possible failure.Look for capacitors that may have gone bad, they will be bulging from the top and bottom and may be leaking material from inside of them. Any component like this needs to be replaced. You may find burnt resistors and other failed components that will require a digital voltmeter to test.If you have expperience with this type of repair you might be able to isolate the problem and replace the parts. This may require the help of service information due to the complexity of the receiver's operations. Try to get a schematic or service manual from the web or a repair shop. This will have all the parts and a diagram of the all the different sections of the receiver. Usuall there is a power supply section, a tuner section, a preamplifier section, and a amplifier section. There also could be a equalizer section and other sections according the functions of the receiver. The failure most likely has occured in the preamplifier section or amplifier section. The problem in the preamplifier section could be a signal diode failure or a signal amplifier failure. in the amplifier section the problem could be in the output power devices which may be transistors or ic's depending on the type of output amplifier use in the unit. Usually not that hard to find with good service information and test eauipment.You may want to take this to a school that teaches electronic servicing and see if they will work on the unit for you for the cost of parts and a small labor fee. Call them first and see if they can help you out. I hope this helps you with your problem.

If the speakers themselves work fine, then the problem lies within the amplifier output. The channels can go bad after hard use, they can be repaired but it may well exceed the cost of the amp if it is not just one channel. Also be sure that you are hooking up speakers that are rated for your amplifier by matching the OHM resistance of the amplifier to compatible speakers.

The relay is soldered onto the circuit board. Unsolder the connections using solder wick. Solder wick is a fine copper braid that soaks up solder as it melts, leaving the connection clean so you can remove the old part. You also need an appropriate soldering iron and solder for electronic work. Rosin-core solder, small diameter, and a 40-watt iron are sufficient.

Once you have the correct replacement part, remove the old one and solder the new one to the circuit board in its place.

Check that it's center speaker in the set-up menu is on and that the sound field that it's in uses the center speaker. try it in pro logic. It could be a bad solder connection on the speaker terminal or on the relay in the receiver.

check the speaker's connections, I got them message when a speaker wire was unplugged and plugged back in while the unit was powered on

Your optcal line may have a break in it ! try another opt cable or try useing the digital cable out!

Why dvd sound does not play on sony str-dg510?

Hello, headbanger here again. I have fixed the amp myself with 3 relays from an electronics company, the number on the relays can be seen by taking the cover off. The three speaker relays are at the back of the circuit board, there is a fourth relay for the power switch but it is at the front of the board. I did replace all three instead of the bad one as it was only $2.68 for each relay. The most important thing is the pin spacing on the relays, there are different relays that do the same purpose that have different pin postion, they will not fit into postion as the pins are only long enough to fit exact.I live in Canada and a company RAE Industrial Electronics Limited at Burnside Industrial Park in Dartmouth, Nova Scotia ... Their phone # (902) - 468 - 1238 ... Fax 902-468-5887 ordered them in. The part number on the receipt is ALA2F12 - RELAY,DPST, 3A 12VDC .. The sales order number on the receipt is 43771-2. Well that's about all the info i have, hope it might help with someone else. Paying $10 to fix my amp was well worth it, having a friend at work with electronics experience helps alot too. He did all the leg work for me to find them, bought him a dinner at work for his effort. My dishes at home are rattling again. OYEAH.

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.
