I have a Sony STR-AV770 receiver that has stopped
your question depends on how good you are at electronic diagnosis (symptom diagnosis) and how adept you are at removing and installing electronc components. first you have to determine why the amplifier has stopped working on the left channel. Make sure that the problem isn't a simple one, take the speakers off the right side and hook them to the left side and see if you get sound. If you do,, then the problem is the left speaker or left speaker wire. If you don't get sound then tyr taking the input that feeds the right channel and pluggin it into the left channel and listen for sound, if you get sound now the problem was the signal from your source not being sent down the left side.
If it still doesn't work you need to move inside the amplfier, but first, get close to the back of the amp and give a sniff, do you smell anything (a pungent burnt wire or rubber smell) if you do, the the chances are good that some components have burned out. Do you recall having a shorted speaker wire on the left side? shorted speaker wires are notorious (especailly older equipment) for burning out the final amplifer stage. If this was an expensive amp it might be worth fixing, if its not worth much then maybe you should consider religating it to use as a monophonic amplifier (one channel) you could use it to power a sub woofer in a hibryd stereo or surround sound system.
I don't know what more I can tell you at this point. If you go through the steps I outlined, and want to tell me the result I shall be glad to respond and maybe give you another direction to head in. good luck and I'm glad you are adventruous enough to want to try.
Volume knob of sony icf- sw 7600gr radio stuck on high volume. Cant be reduced
Recently I found a Sony ICF 7600GR with same issue.... Radio runs full volume.. can't be controlled... Found a SMD package capacitor C252 ,1uf was short.. 1.2Volt was missing on pin number 14 of IC 203
Check these voltages of IC 203 ( CXA1522P)
Pin -15 Voltage is 1.3V
Pin -14 voltage is 1.2V then" No/low Volume".
Pin -14 voltage is below 0.5 then "Full Volume ".
By varying volume control (RV204 , 50K) , Pin number 14 of IC 203 must vary between 0.3V to 1.2V.

How do i fix my sony mhc-gnz888d reject and stand by problem?
The "Eject" and "Standby" display issue on your Sony MHC-GNZ888D could be caused by a variety of factors, ranging from simple glitches to more complex hardware problems. Here are some troubleshooting steps you can try to address the issue:
- Check Power Source and Cables:
- Ensure that the power source and power cables are properly connected and providing a stable power supply to the system.
- Try plugging the Hi-Fi into a different power outlet to rule out any issues with the electrical supply.
- Reset the System:
- Unplug the Hi-Fi from the power source and wait for a few minutes.
- Plug it back in and try turning it on again. This can sometimes reset any minor glitches in the system.
- Remove and Reinsert Discs and Tapes:
- If you have any discs or tapes in the player, remove them and make sure there is nothing obstructing the mechanisms.
- Disconnect External Devices:
- Disconnect any external devices (USB drives, smartphones, etc.) that are connected to the Hi-Fi and try turning it on again.
- Check for Jammed Mechanisms:
- Open the disc tray (if applicable) and visually inspect for any obstructions or jams. Gently remove any foreign objects if you find any.
- Cassette Deck Maintenance:
- If you're not hearing the usual clicking sounds from the cassette deck, there might be an issue with the mechanisms.
- Try opening the cassette compartment and visually inspect the mechanisms for any obstructions or damage. Ensure that the cassette deck is clean and free of debris.
- Cooling and Ventilation:
- Make sure the Hi-Fi has proper ventilation and is not overheating. If it gets too hot, it might automatically go into standby mode.
- Seek Professional Repair:
- If none of the above steps resolve the issue, it's possible that there might be a more serious hardware problem.
- In such cases, it's recommended to contact Sony customer support or a professional audio equipment technician for further diagnosis and repair.
Remember that working with electronic equipment carries inherent risks, and if you're not comfortable or experienced with troubleshooting and repairs, it's best to seek professional assistance to avoid potential damage to the equipment or harm to yourself.
