Question about Audio Players & Recorders

1 Answer

My Onkyo TX-DS777 won't come off of standby mode. I've tried other suggestions including unplugging it, taking off the casing and looking for anything unusual, checking all the wires, etc. Nothing seems to work. Is there a particular area I should be looking into once the casing is removed?

Yes the heat sink (aluminum block) in side has a few transistors on it. see if there is any burns or black char if so the problem is in the amp. if not it may still be there but could also be in the power supply.

also any corrison or cold solder joints ( broken or cracked solder pads), anything burnt or broken poped.

Tx-ds777 no sound from front speakers on a speakers work on b but if I run a and b the center and surround stop working


Hi MJ, If you run your B speakers you will drop your 2 surrounds as the B speakers are meant to be used in a different room. I would suggest that you give us a call so that we can try some troubleshooting, please call our Product Support Team at 800-229-1687, Thanks, JT

Onkyo TX-DS777 does not retain settings after power loss


No internal battery, a large "SuperCap" on the main board acts as one. Look for C8007, 0.1 F, 5.5V.

Home Audio problem


Have you looked in the manual for TROUBLESHOOTING: No Power?

It suggests unplugging the unit for a short time, then plug it back in, then check for a blown fuse, then take it to the ER.

Hello, i've had a problem with my onkyo tx-ds777 for some time now. i've noticed when it warms up and runs for a while, it cuts off by itself. you can only turn it on when the room temperature is cool...


What I've found was bad solder connections on the audio output board.
I Don't know if you are familar with soldering procedures or not.
I would highly suggest not trying it yourself, if you're not a soldering professional. You WILL cause more damage to the unit, ok?
Check with your local audio servicers for estimates.

My Onkyo TX-DS777 lost power. I believe this to be a blown fust, but am uncertain, any thoughts?


It seems like the internal fuse to me, too. But you could check to make sure that the receptacle works (maybe you've got a tripped breaker).
The manual also suggests unplugging and re-plugging the unit to clear "external noise" from the "computer circuits," but something tells me that you've already tried that.

Onkyo TX-DS777 goes straight to protection mode


Hello.You have shorted audio outputs. One of your channels has shorted output transistors. If your unit uses output ICs then one of them is shorted. Both types ( individual transistors or ICs ) are located on the large finned heat sink. The parts are available from http:\\www.tritronicsinc.com. good luck
