Onkyo TX-DS698 stuck on DVD only. Cannot change to any other option. Appears to be locked.

If your Onkyo TX-SR602E receiver is stuck on the CD input and doesn't change, there could be a few possible causes for this issue:
1. Input Selector Issue: The input selector switch or button may be malfunctioning or stuck. Try pressing the input selector button repeatedly or cycling through the available inputs using the remote control to see if it frees up and allows you to change the input.
2. Remote Control Issue: If you're using the remote control to change inputs, it's possible that the remote control itself is not functioning correctly. Replace the batteries in the remote control and ensure that there are no obstructions between the remote control and the receiver's sensor.
3. Signal Connection Problem: Check the audio cables connected to the receiver's CD input. Ensure that they are securely connected and not damaged. Try using a different set of cables or connecting a different audio source to the CD input to see if the issue persists.
4. Internal Circuitry or Software Issue: If none of the above solutions work, it's possible that there is an internal issue with the receiver's circuitry or software. In this case, it may be necessary to have the receiver inspected and repaired by a qualified technician.
5. Reset the Receiver: Try performing a factory reset on the Onkyo TX-SR602E. Consult the receiver's manual for instructions on how to perform a reset. Please note that a factory reset will erase all custom settings and configurations, so be sure to back up any important settings before proceeding.
If the issue persists after trying these troubleshooting steps, it is recommended to contact Onkyo customer support or consult a professional technician for further assistance. They will be able to provide more specific guidance and help resolve the problem with your receiver.

Hello
I Would suggest to try this, pull out the power cable from the wall socket, and while holding down CBL/SAT, press ON/STANDBY. and plug in the power cable again.
hope this will work.

‘I have a onkyo av receiver Tx-sr309 that is stuck on BD/DVD mode and no other keys/buttons on the receiver nor the remote functions. Not possible to do factory reset as well. Kindly help’ Of course, no reset is allowed due to single task MPU.

This is a very easy issue to fix and a common faulty situation found in onkyo AV-amp. If you want to know how to fix, just send an email to me if you want. It is up to you to do so and email will be deleted after ONE week. I won‘t tell you here due to buying faulty AV amps to repair and sell them out on web.

Try pressing and holding DVD button and pressing power button. It should reset it to factory settings.

Hold Video 1 and Press the power button then turn it back on i had the same problem

Check for a stuck switch. If all the switch feel okay, Try to reset it. Check your owners manual it may tell you how to do it.

The microprocessor may be locked up. While pressing and holding "video 1", press "speaker A". When "clear" appears in the display, the micro has been reset to the factory default condition. To do a full reset without taking it apart, it may have to sit up to 3 weeks for the backup battery to run down.

The only remote that will definitely turn the sat subtitles on/off is the sat remote. The other subtitle buttons on the other remotes refer to the DVD subtitles and the subtitles generated by the tuner in the tv. The subtitle option is greyed out on the tv because you are not on the tv tuner.

Hold video1 and press speakers A button, it will say "clear" If the message protect appears again, then its service time.

Did you change your TV input to DVD as well?
