Onkyo ht-rc180 standby light blinks will not start.i tryed factory reset, still blinks

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

I have an Onkyo HT-RC230 receiver. Comcast recommends 30135 or 30842 for programming the universal remote (XFINITY DVR 3-Device remote; silver with red OK button). Unfortunately, the first code only turns...

I'm sorry that the codes are not working with the Remote to control Onkyo Receiver. The exact codes are 0135, 0842. Please follow the below steps and use these two codes again and check if that helps.

  • Find the 4-digit code number for your device.
  • Manually turn on the device you are setting the code for (used to verify you have the proper code).
  • Press and release the device key you want to program.
  • Press and hold the "Setup" key until device key blinks twice.
  • Type in the 4-digit code using the number keys.
  • If successful, you will get 2 blinks. If not successful, you get one long blink.
  • Use the remote to operate your device (use Power, Play, etc..)

If the above codes are not working, please try the following codes and check if that helps.
0531 1023 1027 0074 0189 0531

Thanks for understanding. Please let me know the result.

Cannot find code to set my cable remote to turn on/off my receiver

The Remote Code 1789 will both turn ON and also turn OFF the Onkyo TX-SR605 AV/Receiver. Many codes will either turn it on or turn it off, but not both. Code 1789 will do both.

You didn't mention which setup code you're using, or explicitly say whether the OK/Select button is red or gray (the manual you're using is for gray), so these are somewhat generic instructions. Should work, though. This will provide a power toggle function to the Power key.

Use red numbers for the red OK/Select button remote, grey numbers for grey button remtoes.
Temporarily assign setup code 30842 or 0842 to AUX
1) Tap AUX
2) Press Setup until 2 blinks
3) Enter 30842 or 0842The remote should blink twice

Assign NEC1 IR protocol device 210, subdevice 108, function number 203 to Power (you don't need to understand these numbers)
1) Press Setup until 2 blinks
2) Enter 994 (2 blinks)
3) Tap Setup
4) Enter 00051
5) Tap Power (not All On)
The remote should blink twice

Assign setup code 30135 or 0135 to AUX (this is NEC1, 210.109)
1) Tap AUX
2) Press Setup until 2 blinks
3) Enter 30135 or 0135
The remote should blink twice
