Problem with front signal

SOURCE: No power

disconnect everything from the unit and see if it still does it.
if it does i would check the output transistor (ic).

Yes on the back panel

if you have a tv with outputs you can connect audio wires from your tv output to your audio receiver input and you will have surround sound for everything connected to your tv

Testimonial: "That's a good idea. I hope that my TV will output the hdmi audio through the optical output on it. Thanks"

Hi,

After doing all this troubleshooting on your receiver, Check if master volume on the surround levels are too low. Adjust master and surround level.

There may aIso incorrect selection of the input source. Select the correct input source.

If after doing this the problem still continue, it means the sound ic in the receiver is damage. the sound ic brings out the sounds from the receiver. You will have to open the receiver to locate the sound ic in the receiver and use the multimeter to read capacitors and change the damage ones.

Thanks for using Fixya.

Generally speaking, an amp protects itself from heat, shorts and overloads 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 'naked'. 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 as a root cause for intermittent shutdown.
