This unit has an issue with no/intermittent sound output.
Appreciate all who read this.
Here is the thing Im listening to stereo music on it as I write through the preouts front left and right...but it still has its problems...
When powering up there are no problems...display works..all buttons seems to do what they say...yet no sound.
The problem is no sound even via headphone or preouts or speakers.
But then sometimes if you select DIRECT and if you turn either the volume knob or adjust volume via the remote...up and down you hear clicking..then maybe a slight pop...then continue up and down...and then you can settle on a spot where the sound will suddenly start...and as long as you dont touch the volume anymore it will continue to push sound out. But further sometimes sound is out one channel only...it can change to the other channel..and rarely both channels sound outputs.
Also weirder.....sometimes you can hear via headphones quiet sound from one channel..but its coming through all inputs...no matter which one you select ..you can still here it quietly.!
Ive replaced the power filter caps...and gone over the main board looking for poor solder joints and reflowed where appropriate. But issue has not changed.
Started to wonder if its a bad Sound Processing/Volume Tone Chip ..which is a M61516FP. (ICS03)
I dont want to bin this old beast if I can help it...hoping someone with some knowledge or experience may make some sense of this.
Cheers and Thanks in Advance!
