Question about Sony STR-GA7ES

1 Answer

Protector flashing My Reciever won't operate as the Protector warning keeps flashing when I turn it on. This receiver is plugged into a surge protector and has been for years. Other appliances on this surge protector are operation just fine. I removed the receiver and plugged it into an outlet in another room will everything disconnected from the back and got "Protector" flashing again. Is there a fuse or something that I can replace?

    We also have the Sony STR-GA7ES receiver. It was working fine when it was shut off the night before and the next morning it is blinking "protector". It is plugged into a surge protector and we replaced that but that did not make a difference. Everything else plugged in is working fine. We checked all the connections and everything is okay. All the owner's manual says is that there is a short circuit-eliminate the short circuit and turn it back on. Any suggestions?

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

My stereo just quit on me there was bad weather but it was on one of those power surge cords it is a pioneer stereo fm-am digital synthesizer tuner


If it was plugged into a surge protector, check the surge protector warranty. There are A LOT of surge protectors that will cover damage to items plugged into them through their warranty system. I've had full home computers and TV's replaced by surge protector companies to avoid having a hit to homeowners insurance.

My Kenmore elite microwave is plugged into a surge protector and keep tripping the surge protector. I cannot use the microwave for more then a minute before it trips. Can you help


Your microwave is pulling more amps than the surge protector can handle. Remove the surge protector from the circuit and plug oven into wall outlet. Preferrably a GFCI circuit. Or you could puchase a surge protector with a higher amp tolerance.

The stand by light keeps blinking, this has happened before but then the TV came on. What to do as it has been blinking for a long time now.


The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
  • If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
  • If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
  1. Turn off the television. IMPORTANT: For a projection TV that uses an internal lamp, wait 5 minutes after turning off the TV to allow the lamp to cool before continuing with the following steps.
  2. Unplug the TV power cord from the electrical outlet.
  3. Let the TV remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the TV.
  5. Turn on the television. NOTE: If the TV does not turn on immediately, the fan may need to finish its cycle. This is part of the cooling process for some projection TVs and is normal operation. After the fan turns off, attempt to turn the TV on again.
If the issue is still unresolved after following all of the troubleshooting steps,service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.

I keep getting a Protector reding on my screen and it will not let me do anything. What do I do to fix this?


Try disconnecting everything (speakers cables, signal cables, all other units) except the power cord, then turn the unit on, if the protector message persists, then the fault is in the reciever.

If this is the case, you should check the speaker and signal connectors for any damage, shorts or loose solder contacts, also check the unit for any shorted or broken wires, loose wire connections, bad solder contacts on connector pins, bad solder contacts on ANY other components (give some extra attention to the components that tend to warm up while they operate, like main power amp transistors / ICs, voltage regulators, power resistors, diodes, also coils, capacitors, etc). Any loose solder connections should be resoldered.

If there's no message when you've disconnected the outside equipment, you have either a bad speaker, a bad speaker cable, a bad signal interconnection cable, or a fault in any of the units that were connected to the reciever. You can find which one is the cause by turning the reciever off, then connecting one cable or unit, turning the reciever on again, see if there's a message, if there's none, turn it off again, connect the next unit / cable and so on, until you get the protector message. The cable or unit that will make the message appear is most probably the cause for the trouble (there might be loose solder connections on other units' cable connectors or other components). When you plug and unplug the cables many times, with time this will loosen the solder connection on the pins inside the unit, so these need to be resoldered.

Hope you can find out what it is.
