My sound on Onkyo HT R 548 stopped working

If this is a Surround Sound System you can check channel and audio tone levels using the remote. Check remote for a receiver button followed by Test button. Check manual for test instructions.

The screen keeps flashing rear chk and the rear speakers are not making any sound.

I had the very same problem, and found that if you power up the receiver in DVD/CD mode, or tap the function button to display DVD/CB mode, the Wireless Rear Speaker AMP will automatically recognize and turn on the sound. This work around was not posted anywhere in the manual, just 1 of many workarounds I have had to put up with this system to work. Right now my fan went and it just keeps shutting down, I have had this system for about 15 months and very disappointed with the quality. My DVD player stopped working a few months ago, so now the system is rendered useless, not even sure it is worth fixing at this point since it is no longer under warrenty.

Power botton not responding

If it's not ejecting or responding to any of the buttons on the unit, or the remote, but is able to play a DVD, the display microprocessor(computer) within your Harman is damaged. For more information, please visit my website at Thank you.

No audio is coming through my speakers

If the receiver is actually powering up but you are getting no sound, there are few basic things to check.

Check the audio connections on the back (speakers AND inputs) to make sure they are tight at both ends and undamaged. Go into the setup screen for the DVD player and make sure the audio settings are set for PCM output and that you are using a digital or optical audio cable. Then make sure you have the correct function selected on the receiver to match the inputs. If the receiver has a speaker test function, use it to see if there is any output from the speakers. Finally, make sure the volume is turned up and the mute button is off.

Otherwise, the amplifier may be faulty

If you're NOT still under warrantee you should at least open the reciever and look for a blown fuse near where the power cable enters the set. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the receiver to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your reciever serviced.
