Sony elektrosztatikus magassugárzó
Üdv! SA-EX100 aktív hangfalról van szó, a magassugárzója alig szól, szoktak ezek az elektrosztatikus hangszórók így megdögleni?
Sony STR DH130 protection mode
Friends Sony STR DH130 goes into protection mode soon after turning on.  It works for a second then can hear loud pops from speakers.
I've tried the suggested methods to fix but nothing works.  Correct impedance speakers.  Speakers wired correct.  Good ventilation.
I've tested the output transistors in circuit and I don't see anything unusual.  I may pull them to test but will wait for advice here.  I also measure
about 57 volts on the emitter resistors.  Seems high to me.  Anyone?

Sziasztok! Van egy Sony CDX-R3300-as autós CD, ami a bekapcsolás után csak a demo-funkciót végzi, semmit nem lehet vele kezdeni. A SM-okban semmit nem találtam erről. Tudna valaki segíteni? Köszönettel Attila
