Question about Sony STR-DB840 Receiver
After owning the system for 6+ years now, i just stopped working. It is connected to my PC and LCD-TV on 5.1 input channel. I was listening to music, when I heard a 'strong click' (may be spark) sound (most likely inside the reciever) and there was no more suound from speakers.
I will explain further here the situation.
There is display as normal on the reciever. I can select different inputs from function knob...but no sound on any channel.
There is no sound in speakers, but subwoofer has sound, I can feel that by raising the volume.
Is it a something which can be reset? or fuse ? protection mode?
thanks for reply
There are 4 blue relays in the unit that has solder points that will crack over time.
It´s fairly "easy" to re-solder them and viola, it´s OK again.
open the cover (unscrew and take of the hood) and locate the 4 blue relays. Unscrew and remove the bottom service plate and locate the soldering points for the 4 relays.
Each relay has 6 solderings, 4 in one "groop" and 2 in one "groop" look especially at the "2-groop" these are the ones most likely to crack over time ( for me 12 years or STR-DB840 no sound in speakers - 3436d08.jpgc="http://i.fixya.net/uploads/images/3436d08.jSTR-DB840 no sound in speakers - e6f7344.jpg36d08.jpg" class="h_mi" />
Re- solder. Best of luck //Ronnie Stockholm
