Hi, you like your sound loud like I do-to prevent the stereo from shutting off simply turn the " BASS " control down a little- 1/3 to 1/2 of full should do the trick, write back to let me know if this helped, good luck and thanks for asking FixYa-Prodzilla.

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.

Sound problems/ receiver

NO., it cant be played thru both when it is in cd/dvd mode because from manufacturing it vl be like that. it cant give its sound to other when in cd/dvd. how am telling is i have YAMAHA yht-165. when i use dvd mode.. the sound wont get thru its output. only works when its in other modes like tuner, md-r, tv, aux.
