Question about Electronics - Others

1 Answer

Home theater I have a Harmankarden receiver AVR 240 that now continues to give the "Protect" wording on the main panel and then shuts down. I've looked through the system manual and can't find the answer. Please help. The higher the volumn the sooner it flashes and turns the unit off even when only at half power.

Check to make sure that your speakers' ohm rating matches the amp.
Also check every speaker connection carefully for stray strands, poor connections, etc.

My sony mini hi-fi deck continue to tell me to i quote 'PUSH POWER;PROTECT' what do i do?plss help.


You PUSH the POWER control (OFF) because it is self protecting.

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 'nekkid'. 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 for intermittent shutdown.

M getting protect on my stereo display


It is possible that your device is shutting off due to a short in the circuit. hence for protection the device is switching offf the powerr to the main circuits. You will need to check for the short , maybe outputs or drivers and disconnect, replace to confirm. since you have not mentioned the model I am not able to comment more. Good day

How can i connect Nintendo wii to avr-590. Have


To connect a Nintendo Wii to an AVR-590, I am assuming this is a Denon Receiver, you will need to connect the Nintendo Wii to the TV, then connect audio out from the TV to the AVR-590 Receiver, and select the receiver to be in Pro Logic. Depending on the TV, if you have fiberoptic output on the TV, you would hook a fiberoptic out from the TV to the AV Receiver, but you will still not get true Dolby Digital, just Dolby Pro Logic. This will be the most effective way to solve the problem. Hope This Helps

We have run our indoor/outdoor wireless speaker through our home theater system and the only sound we can get is in tuner mode. We are trying to run our tv through the speaker, any suggestions?


connect audio out from tv to audio in(aux in) on the theater, select aux on theater and you should get sound.
If you have no audio out on tv, use skart 2 (av2 au2 or how ever it's marked as most tv's send audio/video out through av2).
You can buy any comination leads to connect(skart to phono etc)

OVERLOAD


I had incountered before VICTOR colored TV.ive found out that the problem was in the switch relay on the power supply area.. My suggestion is to check the relays wich is located at the supply board area resoldered the pin to make sure the pin is in solid contact. or put an AVR back up to your TV. If the problem still occur check the regulator IC or try to change a new IC this might help the problem.
