I have had this sub for quite sometime without any problems at all. Recently when i turn my receiver on the light that is normally green on the back indicating it is on goes red for 'standby' and the sub will not work. How do i fix this?
I was able to take care of this issue by talking to Onkyo tech support. They diagnosed over the phone and concluded that the receiver set the volume for the sub way too low (-12), therefore sub was not receiving the input and was doing what it was supposed to be doing. They walked me through manually increasing the volume and now everything works great.
Good luck! I hope this helps.

Dive back into the setup and make sure you have the sub defined (page 19). Run setup. It should work.
If not, tune FM, run an RCA cable from either Record Out channel to the sub's input; or connect a CD directly to the sub. Gradually raise the volume with something bass-rich playing. That ought to wake it up. If not, the sub is dead.
I HAVE 4 PS212 AND FROM WHAT YOU ARE DISCRIBING SOUNDS SIMILIAR TO WHAT HAPPENED TO ME. PLAYING THE SUB AT FULL VOLUME AND CLIPPING OCCURED NOT KNOWING THAT THE FAINT SMELL WAS THE VOICE COIL BURNING AND CONTINUING TO PLAY UNTIL KNOW SOUND LESSON LEARNED BUY A BIGGER SUB SYSTEM OR REPLACE YOUR SUB WOOFER.
IN MY OPPINION THIS IS A VERY GOOD PRODUCT WHICH I HAVE BEEN ABUSEING FOR MONTHS . SO QUIT WHINEING AND PAY YOUR DUES.
sharazanct I had the same problem and posted here many months ago without any success. Just today, believe it or not, I decided i would replace the screws in the top cover and try it one last time. I don't know why, but it now works fine.???? My original problem was my receiver would light up and appeared to be working but I would get no sound out of the sub or speakers. I noticed at the time when I would first turn the receiver on the green indicator light on the front of the sub would light for a couple of seconds and then go out and would get no sound. Today the sub light lit and stayed on and I'm therefore able to hear sound as if everything was normal. I wish I knew exactly what I did, unfortunately I don't. If you have everything back together you might try unplugging the receiver and sub for some amount of time and come back and try it again. Good Luck!
Check the solder connections on the seven voltage regulators found in the center of the receiver on the heat sink from front to back (not the amp board) they are on the main board. The green light on the DSP board (back right side) is an error light. You can reset the receiver by pushing power then stadium then night then dsp off then club after unplugging the receiver and plugging it back in.
hey buddy, I have the same system, and although I haven't experienced it on this one, I had the Harman Kardon equivalent to the TSS-750, and the sub did this same thing. It was a loose RCA connection, and, as I was well outside of warranty, I took the amp out of the back and just re-soldered the connection myself. It now functions flawlessly for my bedroom setup. I hope you get it all worked out on your system! I can't imagine using this awesome system without its deep notes!
There is a standby indication that activates after 10-15 minutes without any input signal. I suspect that might be what the red light is telling you - no signal.
Loud hum from a loosened cable is normal as hum usually means there's an ungrounded connection somewhere acting as an antenna and the amp is doing its job to amplify what it thinks is a signal, in this case 60hz stray ac current is being sensed nearby. It's a good sign that you get hum from the sub because that means the amp is alive.
Avoid manipulating cable connections with the Sub or Receiver turned on as you could introduce a static spike that could harm any connected equipment.
Are you certain a bass signal is making it into the sub? The complexities of modern AV receivers vary in how you configure them to direct LFE to a sub. Bone up on that end of the chain.
Or, just hang a CD player on the Inputs of the sub and play something with a reassonable amount of Low Frequencies.
>>>> Be advised that this way of testing has NO VOLUME CONTROL because amps without volume controls always operate at maximum gain, relying on your external controls to attentuate it (hence, the loud hum from a loose cable); so choose a track that eases into the loud parts with some quiet parts up front and BE READY TO PAUSE THE PROGRAM AT ANY SIGNS OF STRESS. <<<<
A living sub will produce only muffled rumble in the absence of other speakers producing the higher frequencies which carry the intelligence of the signal. If that works, back to the receiver for settings. If not... sigh.
For hum problems, even those you cause yourself:
Disconnect all inputs to see if that helps. If it goes away start with the signal cables and add in things until it comes back.
Sometimes the reversing the orientation of the AC plug can help with hum. Or it could be something like a loose or high resistance connection internal to the sub. Good luck.
I felt supid this morning.
I bought a high end cable for my subwoofer.... and it did not work but a regular RCA Cable did. When I went to put the cable back in the package I saw an arrow pointing one way, I turn the cable and it works great.
