Question about Sony STR-DB780 Receiver

1 Answer

Audio out problem

I have been using the Sony DB 780 for 3 years with much satisfaction. As a result of moving houses the amp/receiver remained idle for one and a half years. Few days ago I wanted to put it back in place and realise that:
1. front speakers no output 2. sub woofer no output 3. rear speakers plays faintly 4. center speaker output excellent.
Could someone tell me what the problem may be and what could be done? Best regards.

Sounds like your sound output ic may have gone.this is normally connected to a heat sink.also check that sound output settings are ok before you go further

Was idling 1000 adjusted idle to 780 now truck wont start unless you step on fuel slightly,then starts immediately and idols at 780


Depending on the year make & model, nowadays the computer in in charge of the idle adjustments. Try to readjust it back to where it was & check the result. You may need an idle control valve, throttle positioning sensor, vacuum leak etc.

On a sony str-dh710, is there any difference in the amp. level between setting the distance levels and the db levels? Also using the Video 2 input on the front of the reciever I'm not able to get any...


.. or read the manual about setup and getting multichannel audio from 2-channel sources. Calibration and Selecting a Sound Field.

Distance is linear spatial separation of two points. dB is audibility, sound pressure level, volume. The distance setting affects how the various channels are delayed to arrive at the primary listening position at the appropriate time to provide a plausible sound field. Simply making one or more speakers louder or softer will not affect the spatiality of it.

My Sherwood RD-6105 shuts off if I turn it up past 28 or 29 db (which isn't very loud). I'm using it in Dolby Digital mode. It even happens when I use it with my components that are analog. This just...


It's acting as if a short or near-short exists on the amp outputs at medium levels.

Disconnect one of your speakers at a time and try it. Make sure your speaker wires are tight and not shorting to anything and all channels have 6-ohms or more load.

If the problem is no audio recorded from the internal microphone, then it has likely failed. See http://www.bealecorner.com/trv900/trouble/micfix/index.html for a simple repair procedure you can do yourself.

Sony STR DB-930 Receiver jumping into protector mode


I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.

Regards

Darryl.
