Sziasztok!
Vásárlás előtt szondázom a piacot :) Van gyakrolati tapasztalatotok a Sencor hangszórókról?
Hasonló kategóriában kapható JVC, Sony is (szerényebb műszaki paraméterrel, kicsit drágábban).
Vélemények?
Természetesen nem Audiofil hangzást szeretnék varázsolni 15 éves autómba :D Csak a gyári 6W-os hangszórókat szeretném kicsit modernizálni...

Tisztelt Kollegák !
Kapcsolási rajzot keresek egy rendkívül fontos javításhoz.Persze a tulaj fontos
a készülék elég siralmas.Meg kell javítanom.Egyenlőre nem szól, de programozni
lehet.Tehát a tipus: Grundig prima boy 100 G.RG15 táskarádió
Segítségeteket nagyon köszönöm,
üdv. hanuman
Sziasztok!
Hanghibával kaptam javításra a fenti fejegységet. Az a gondom, hogy kódot kér, így asztalon nem tudom bekapcsolni. A tulaj nem tudja a kódot, mert az autóban nem kéri, viszont ott nem tudom javítani. Kódfejtésben nem vagyok jártas ezért kérném a segítségeteket. Mellékelem a rajta található címkéket, és egy képet az előlapról.
Üdv.
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?
