How do I reset the protector


By "the unit" I take it you're referring to some audio device? If so, you most likely have a short in the speaker wire.

When home theater is turn on, protector push power is flashed on thee screen. player will not function further. volume level is 9. currently can't be turn down.


Protector means there is a short circuit somewhere in either the speakers, the wiring or inside the unit itself....you can try disconnecting all the speakers and then turning on the unit...if the protector goes away, then you have a bad speaker or bad wiring to the speakers....if the problem stays, then there is a faulty circuit in the receiver itself and will need to be serviced

Error code - protector


Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.

CE code flashing and have hit the stop-cancel and everytime i go to start it goes right to CE flashing,,, which i hear is a communication problem do you know how to stop it or fix it


CE Communications Error If there is any breakdown in communication between the machine controller and the motor controller, CE flashes and the unit beeps once.

Some common causes of CE errors include:

· Conformal coating on serial communications pins between the machine controller and motor controller. After disconnecting power to the unit, try scraping this coating off the pins.

· Check the resistance values between the serial communications pins with the connectors in place. Make sure the harness does not have a bad connection.

· Check the quick disconnect at the motor terminal. The drive motor must be hooked up properly or a CE error will occur.

· Drive motor thermal protector has opened.

·Motor controller is not powered or fuse has opened. Replace motor controller.

Press STOP/CANCEL to clear the display.

Sony KDP-65S550 red light keeps blinking


The STANDBY light is flashing on the television and there is no picture or sound. Solution
sp.gif sp.gif The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television 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 television.
  5. Turn on the television.
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.

Protector flashing


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.
