    I have a 939 that the display has not worked for a couple years. It was intermitent at first, could tap on the case and sometimes would work. then it would work for about a minute on startup and would go off then. Probably a joint but what board would I look at. Now which this has happened just a few times in the last week- all settings go back to flat and may not even power up. No click when pushing switch or anything. Tapped (pretty hard) on the case and now is working again. Might just go and buy a onkyo 805 from crutchfield for $ 699 and be done but looking for a little hope..... But I paid alot for this thing new and was hoping to get another 10 years out of it......

On my device there were quite a few bad solderings on power card. May be you have the same and it does not tolerate heat. Power card is that horizontal one on top, when you open the box. It is easy to remove so that you see under the card to check those solderings. One screw from left side of case, which holds that noise eliminator on AC lines, six screws from back keeping those connectors and four screws away from board corners. I disconnected only that connector in the middle of card, because it was a bit tight. Then I was able to turn that card upside down and after some fixes to those bad solderings device is like new again.

Problem with onkyo tx 919 unit


Hi...
If you've had it "fixed" 3 times and the problem comes back either you have the wrong impedance (ohms) speakers connected or the power supply in the unit is the actual problem.

Happy new years,

ONKYO TX-DS939 (sound and heat/fan issues)


This sounds like the amp is seeing too small an impedence load. In other words, the amp is expecting to see an 8ohm load and is being presented a 4 or 2 ohm load. This will force the amp to work really hard and generate excessive heat. Does the amp generate sound at all? ever? If not, then you probable have a situation with high frequency oscuillations that you can not hear. This means that the amp is sending out a lot of power to the speakers that the crossovers are shunting to ground. Without seeing the output of the amp with a scope, I can not confirm this. This is not a problem that will be solved remotely. Bring the unit to a shop and request that the output be examined using a scope to check the waveforms. I suspect that a bad feedback look internally is causing the generation of the high frequency signals.

Keep us posted.

Onkyo TX-DS939 optical selection problem help!


That coaxial, opt-1 and opt-2 are available only if they are not selected to some other channel. So you have to check if opt-2 is selected to Video-1,2,3,4,5,6,7,CD or DAT. Change that to Analog and then opt-2 is free to another device.
