Have you re-run the speaker definition and level steps? I can't find the manual. Perhaps you could flip a few pages in the Troubleshooting Section.

Fine audio equipment from Japanese manufacturer's like Onkyo is typically "stand-alone", meaning there often is no universal remote control available that will work a given unit; those that will work are rarely capable of accessing all the features & functions such units employ...best bet is an original equipment remote control; recommend you try going to this site:

Disconnect all speaker wires from the unit and power back up. If it does not go into protection, post a comment and I will walk you thru troubleshooting. If it still goes into protection, it needs to be serviced.

The 0-83 error indicates a problem with the firmware update. Try resetting the receiver's BIOS by following these steps2: Unplug all cables Un-Power the receiver Power the receiver Before the receiver gets into the "Enter for updating" message, press Tone + CBL/SAT + ON/STANDBY. This will show you either the volume numbers or get you into settings of the receiver's speaker configuration. Press CBL/SAT + ON/STANDBY. This will clear the BIOS and show a "Clear" message on the display. Wait until you hear a couple of clicking sounds for the receiver to turn on and off the power.

Hello, To test the subwoofer when the blue light is on if you apply your thumb to the end of the subwoofer cable (the end that you would plug into the receiver) there should be feedback from the sub. If there is no feedback then the sub is not working correctly. Thanks, FJD

You need a RCA sub-woofer cable (analog mono) to connect between the receiver's sub-woofer Pre Out and the sub-woofer. This cable has a single RCA plug at each end of the cable. The cable is somewhat thicker than some audio RCA cables. You can use any RCA cable temporarily. The manual for the HT-R758 is available from Onkyo here: https://onkyousa.com/ht-r758 . The current link to the manual is https://assets.onkyo-av.com/product-manuals/HT-S6500_English_2022-11-02-204020_ivkn.pdf?v=1667421620 . See page EN-13 (page 13 of the PDF) for connecting to the subwoofer. The original package came with a 10' RCA sub-woofer cable, see page EN-1 (page 81 of the PDF) for the speaker list. I hope this helps. Cindy Wells
