Re: Onkyo TX-DS838 Issues

The problem here is that the output amplifier section has a problem. This is detected internally and the system shuts down in a "protect" mode. The output section really only kicks in when you attempt to bring up the volume. Another possibility is a problem in the "front end" where DC current is being passed to the amp section. Without takeing measurements, it is difficult to determine the exact cause. This should be a relatively stright-forward repair for a service shop and should cost about $20-$40 in parts plus the local labor charge.

How can I hook up BIC F12 subwoofer to Onkyo TX-DS838 receiver? Will the receiver power the subwoofer and other speakers?

Get a RCA cable and connect from your amp where it said Sub Woofer in the Pre Out box in the back of the amplifier top left hand side and take it to the "Sub In" located in the back of your Sub woofer bottom right hand (White round connector).
Good Luck!

No music coming from my left front speaker. I ran the level calibration and I can hear the pink noise coming loud and clear to that speaker. I have both front speakers set to the same level, but I only...

Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.

Hope that helps you out!
Thanks for using Fixya!

Onkyo TX-DS838 Receiver. Mine just sparked smoked

Not worth repairing until the root cause of the failure is proven.
The reason being is that you can have it happen again if caused by any of the devices attached to it, such as inefficient speakers.

My onkyo tx-ds838 motor fan do not move

The fan in those Audio System only turns at about 1/4 to 1/3 of the ride of your volume control.
It had been intentionnaly designed like that, to achive a quiet operation at low hearing volume.
But if the fan don't move by cranking up the volume at 1/2 to 5/8 of the volume control (with speakers on). You need to have the fan or the fan power circuit checked by technician.

Error s10

Did it ever work properly? If not, let's get down to basics and set it up for the simplest configuration it can have: FM source in stereo with front left and right speakers, no Surround Mode, no DSP, no Tape Monitor, no Mute, Volume not turned all the way down. Does that work?

Do you have Surround Speakers defined in System Setup A? If not, only Dolby Surround or Off are valid Surround Modes.

Is T2 Monitor indicator lit? Press the Tape-2 Monitor.
Is there acceptable sound other than during Speaker testing? NO? Is MUTE On?

Sight unseen my money says the new problem is a direct result of the 'repair' to the channels that are giving you problems now. You didn't elaborate on what it was you were trying to fix in the first place. Backtrack your steps and undo what you can to see if the bug changes.

Onkyo ts595 goes into protect mode with volume increase

HI check your speaker cables are not touching, also make sure "b" speakers are not on and that all your speakers are 4ohm or higher as this will cause the amp to shut down if they are to low an impedeance,The amp is protecting itself when it shuts down.

hope this helps.
