My receiver turns on for a few minutes, then automatically shuts off. This has only recently started happeing. The red light around the power button flashes when the unit is turned off. Is the unit trying to let me know I need to replace a component or something?

Hi,

your receiver is having a power problem. One or more component(s) on the power board of your receiver is defective, that's why its turning off.

This problem may have occurred as a result of power surge or excess power entering into the unit or irregular power supply.

If you know about electronic repairs, get a meter, use a screwdriver to open the receiver so that you can gain access to the power board. Use the meter to read the power board and replace any bad component detected.

Once this is done, your receiver will stay on and function normally again.

Good luck.

IN104 automatic shutdown


Hello, my infocus in104 will power up for a while (1- 5 minutes) when connected to the power supply and turned on, after that it automatically shuts down. Power button does not light red when it automatically shuts down and need to be unplugged for a minute or more before red power button will light up again.

I have a Emerson LD190EM1 Tv DVD combo. It will not work with my Dish Network remote. What is the IR code?


I also have the same tv with no luck on my dish network with the codes. However, I just did an autoscan and found the code, but it doesn't tell you what code. I am sorry I cannot give you the code, since manually entering them did not work, but the auto scan did work!

To run auto scan follow these steps.... it took me about 5 minutes to find on my dish network remote.
1. Press and hold the tv mode button until all other mode lights flash.
2. Press the red power button (not the red tv power button, but the power button which normally shuts off your receiver only)
3. Press the up button (about every other second) When your remote finds the code, your tv will automatically shut off.... once it shuts off, DO NOT press the up button again.
4. While the tv is off, press the pound (#) button.
Your remote will be programmed to your tv. Turn on your tv with the small red power button with the tv wording and test other functions (volume, etc.)

I tried this last night, waiting about 3 seconds in betwwen with no luck after 30 minutes, just a tired finger from constantly pressing the up button. But tonight I tried it on my LD190EM1 and paused for a second inbetween pressing up and almost fainted when the tv actually shut off within 5 minutes of starting! Best of Luck!!!

Whenever I start playing on my xbox or playstation, the receiver will shut off (the red light is blinking around the power button). Once I hit the button, it stops and then I can turn the receiver back...


does it only shut off on high volume or a loud noise?

It's the amp tripping to protect itself.

look out for a shorting speaker wire or faulty speaker etc. disconnect each in turn to find out which

In a few minutes the light should turn green and start options should appear.

Denon avr-1706 receiver just shuts off


This sounds like the amps protector circuit has been activated due to thermal overload. switch it off for an hour or more to let it cool down, make sure your spkrs are connected properly, don't parallel. Try using a fan on the unit to get that heat away. Get a techie friend to give the insides a once over, and clear away any dust that has built up.

hope this is of some help,
Cheers Kimbo.
