An output transistor has shorted and is drawing too much current. It's fixable, but use a matched pair of output transistors instead of just changing the bad one.

SOURCE: ''Power off ''flashes ten times after the receiver is turned on.

Most often it will require an output IC, but I have seen it be a bad ground or a transistor in the protect circuit.

SOURCE: Harmon Kardon Receiver "Protect" Mode issue

If your receiver enters protect mode with no speakers connected, it is an indication that you will have to start troubleshooting inside.This will involve visual checking and checking with a multimeter to isolate the problem. A further issue is finding out why your JBL woofer keeps blowing fuses. It could be shorted.

Standby indicator flashes


When the "Protection" indicator comes up the display panel of my receiver or the On/Standby LED is flashing, does that mean my receiver needs to be repaired?
The "Protection" light comes on when the receiver's current sensing and thermal monitors detect some unusual operating condition that, if left unchecked, might damage the amplifier. This can happen if there's a dead short in a speaker wire or if you're using very low impedance loudspeakers at high volume for an extended length of time. On older model AVRs you may see the word "Protect" on the receiver's display. More current models will indicate a flashing red light on the Standby LED when a Protection circuit trips
n thermal cases, the circuitry will automatically reset after a few minutes of cool down and the Protection indicator will go out and normal operation will resume. If the protection light came on due to a speaker wire short, low impedance condition or a bad speaker, the receiver's power will need to be turned off to reset it. Before turning the power back on, all speaker wire connections should be checked for their integrity at the receiver side and at the speaker side. If the protection light goes on immediately after you turn on the receiver, disconnect the speaker wires at the receiver side and retest. If the receiver's protection light goes off, then there would still seem to be a problem with one channel's speaker wires or speakers. Connecting them one by one and retesting should allow you to find the problem speaker or connection.
If after checking all your connections, the Protection indicator stays lit, you may need to "initialize the microprocessor (see the FAQ on that topic) or take your receiver to an authorized repair center for a diagnostic. The "Initialization of the Microprocessor" or "reset" procedure can be found in your owner's manual on current model AVR product. Please note, this will erase all setup configurations in the system and require the system to be setup again. You may want to mark down the settings before resetting your receiver to aid in the setup process. If you had an installer setup your system, you can contact them for assistance and any associated costs that may apply to setup the receiver again would be the responsibility of the owner.

PROTECT does not come out from the screen


Check the speaker wires for shorts or damage. If none, the amplifier has faulted and will likely require service to restore back to normal working condition.

Your receiver probably went into protect mode because you were overloading the output stage with concert blast. In some units, protection consists of fuses that blow; in others protection is provided by thermal shutdown devices.

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Tv Turn sound on, No Picture, turns itself off within seconds


The TV is trying to go on protect mode because an internal fault had been detected. For that reson the protection circuit keeps turning off TV continuously.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

TV image goes black for a second and then the picture comes back on


Your issue really requires greater troubleshooting. I could begin to explain the multitude of possibilties but the list would be lengthy. You will be better served to call dish and ask for a service call. If you have the home protection plan it may cost you 29.99 for the tech to come out. If you do not have the protection plan it could be added at the time you contact dish. Ensure you call 1-800-333-3474 to get accurate information. This is Dish Network's Customer service line and not a third party such as a a retailer. Th e problem could be the LNB,foilage,cabling, connectors, groundblock, etc....
Hope this assists you. Thanks for using Fix Ya and please let me know if I can be of more assistance.
