HI YES YOURE GOING TO NEED A FEW RCA CABLES u. can use video 1 to plug youre tv in and use video 2 to plug in youre vcr ::::::::::connect youre speakers up to the red and black speaker terminals marked L & R..good luck

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause forintermittent shutdown.

their are fuses, inside the unit, by the power supply area (transformer)

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

Replace the volume control its bad.

You should see the damage to the part (perhaps even smell it too) which will need to be replaced. I suspect it will be on the big heatsink and perhaps connected to the channel which was shorted out. Check the internal fuses too.

Take it to a pro for that answer.

Check all your speaker connections and make sure there are no shorts where any of the negative wires can come in contact with any of the positive wires.

I believe you have dry joints in output drive it require a qualifier Technician the do this you need special soldering station with anti static you are dealing with surface mount components if you shorted some thing in output drive it could damage to the output they are expensive to replace, now is not too bad you should bring in to Sony or servicce center Sony to repair it

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.
