Hi
I just got my hands on Avt275 that I hope I might be able to fix.
I read through a lot of posts on this forum and I found one that talks about same problem but not solution.
Amp powers up and LEDs are working when switching channels but there is no output. I also tried headphones or emulated line but no luck.
I took all bords out and examine them. There is no evidence of anything being burnt.
Without schematic it is very hard for me to further debug this problem. I spend half a day looking for AVT150 schematics but I was only able to find one page.
Could anybody share schematic? I would greatly appreciate it.
I also read that my problem could be cause by shorted mute circuit.
Does enyone know where it is located?
Thanks for your help.
