Horrible cracking souns through surrounds with TX DS 787

10 years and second repair in need. When you turn on and select DVD a very loud cracking noise comes through all 5 speakers. So loud (with volume tuned off too) that I fear speakers will blow. Any ideas or should I toss this $1000.00 peice of audio and go back to Pioneer/Sony?

If I remember correctly there was a problem with the DSP board that required a chip replacement to resolve this problem. I replaced many of these in the past. The IC involved is a surface mounted IC that is not the easiest to replace. This is not a home repair. I'll double check my notes on this, but once replaced, you should not have the problem again. The problem was an incompatability of the initial manufacturer's IC with the design (or something like that). The IC runs about $25-$40. I'll post additional details when I get the notes.

10 years and first problem to repair. When you turn on and select DVD or any other selection a very loud cracking noise comes through right speaker only. So loud (with volume tuned off too) that I fear...


I think your receiver is damaged.

Try this.

Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right"

Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly.

Disconnect both left and right speakers.

Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on.

IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine.

Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on.

IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver.

If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

TX DS989 turns off after 3 seconds


Sorry but it does sound like an Amp failure and testing the unit for other electronic component failure will be needed

Just purchased a Panasonic DMT-350 with analog 7.1 out and hooked up to my Onkyo 989 but tried everything and i mean everything to get my rear surround to play but no luck....pleeeeeease help me.


Hi.

Connect the Panasonic to one of the AV inputs on the Onkyo. Use red white and yellow AV cables. Connect the output from the Panasonic to one of the five AV video inputs on the Onkyo (or use the DVD dedicated input in the Onkyo backpanel). I indicated this option using red arrows. You can use any of the AV inputs or the DVD input at the bottom. Just ensure you do not connect to an output at the back of the Onkyo.

Alternatively use component cables and optical audio input, as indicated using the blue arrows in picture below. Select source and listen surround from the Onkyo.

There are more options. In some case you may decide to connect the DVD video output to TV and the audio to the Onkyo.

Here a manual for the TX DS989.


Here the backpanel:

Onkyo TX-DS 595 receiver surround channel unrealiable


How you power off the amp won't hurt it generally. I used to fix ONKYO amps under warranty, and I can tell you now, it will be full of dry solder joints. Take you unit to your local repairer, and they will resolder all the offending PCB's inside. This type of repair will fix 99% of strange audio noises and cutting in and out etc. for ONKYO recievers. Otherwise this is quite a good product.

Surround mode is set to OFF


I was able to solve this problem by using the "A" speaker jacks and eventually I pushed the right buttons to get the Surround mode to turn ON. I believe it was when I hit the Parameter Selection button that allowed the surround mode to become active.

If it is me and I am spending that kind of money, it is going to be sick, os here is sick. 7.1 dolby surround and 1080P HDMI, 135W per channel, and right now if you go to FRYS.com, it is normally $500.00 bt for right now it is only $449.00. But if you put this in, be prepared to buy a PS/3 as your next investment (Th best way to get Blu-RaY at an affordable price, plus many other features) and an upconvert DVD layer, which is only about $100.00 or less today. Then you better get ready to hear from your neighbors and the cops, because they are going to think a war has broken out in your place. Enjoy, I play movies that the sound is just so realistic, I hate to leave the house anymore. Also, remember, speaker placement is key, so know the optimal environment for your system and if you need one, I may be able to hook you up with a system room tuning DVD for next to nothing. This will allow you to setup your system and place your speakers optimally for your environment. good Luck.

Onkyo TX-SR500 Dolby Digital problem


I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps.
