Hi i just would to know if you did try to connect your TV by HDMI to test if your optical output of your reciever/amplifier have some problem. In second time yes maybe you can have an overheating problem, just take a look at your grid and maybe a clean-up will be necessary. I don't think your amplifier have a fan. Don't hesitate to contact me here in this post. have a nice day.

Try Retrevo Manuals.com

This is a tricky one. Are you using the Onkyo for only the subwoofer or are you trying to amplify all the speaker outputs?

I need a PNE-S1B1 RJB2318A board too, do you get it, my mails [email protected]

Take a look at the bottom of the unit. Remove the access panels from under the amp ic section and look at the solder connections on the amp ic's. If they have round rings around them, they are bad and need to be resoldered. This can also happens on the voltage regulators that are on the heatsink with the amp ic's.

Newremotecontrol.com has a substitute remote with the same features as the original. Part# EUR7702KK0 for around $29.99. The original remote is obsolete.

Well if you can hear RS then take it to your local electronics repair store if warranty has expired. If you cant hear RS aswell then you might not have the right number of speaker's or speakers setup right. if you have 7.1 then you will have LS and RS speakers if it is 5.1 setup then then rear speaks have an option on most to be a rear (behind speakers) or rear (side speakers

everything should be run to the receiver in ,, then from the receiver out,, heres the instruction manual for your set up ,, http://service.us.panasonic.com/OPERMANPDF/SADX750.PDF

TV's don't play through receivers. TV sound might. If it comes from a Cable Box, connect the Cable Box digital audio to the receiver as you would any other high-end audio device; and the Cable Box's standard analog audio to the TV for those times you don't need the Technics audio capabilites (like watching news).

Have you looked at the manuals?

bad powersupply.

Check whether speakers are working at all:

• Does the speaker indicator light flashes or not?
• Do the speakers emit at least some small noise (try to plug in and out the speaker jack).
• Try to plug in different speakers (from another device, or borrow from your friends or neighbors).
• If other speakers work - try different speaker cords, maybe the cord is broken and you will only have to change cord, not the the speakers.

Try plug the speaker jack in different jack-holes of the DSP (usually the color of the jack and the jack-hole should match).
Does the DSP show any signs that it is operates normally.
If nothing helps - bring it to the warranty repair service (at least 2 years for all electronic devices) or much better - ask for replacement (ask the problems might reoccur for once already failed devices in the future). --------------- P.S. If this helped you to solve the problem (or at least brought some clarification) - rate this solution with 4 thumbs up! Thank you!
