Hi
I got this Receiver STR-DE525 surround sound unit with an unusual problem
well that got me stomped
Came in indicating "protector" so I found 2 output transistors that were
shorted and 1 emitter resistor open
Now the set powers on and the left channel works fine but the right channel
distorts badly
I`ve esr`ed caps around the "power amp" chip (before the transistor output
stage) for the front channels and found they were bad so i replaced them all
to find the same problem...
The inputs of the chip are all fine (with sine wave applied) but the right
output distorts... I did replace the chip and same problem lingers
please anyone who can help?
