Hi,
i'm new, from Italy, sorry but i do not know hungarian :-)
i found on your site the Sony XR-C650RDS service manual, but it is not complete.
Your manual missing the pages from 31 to 48 with the electronic diagram
do you have a complete diagram, i do not found it on internet
Thanks
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?

Üdv.
Ebbe a rádióba kellene, hátha van valakinek. Nekem van egy HQ panel trafóm bele is férne de 6V-os. Túlélné a rádió?, mert a rádió DC-je 4.5V

Kész és átraktam a javítások közé. Ilyen trafó oldotta meg a baját.

Sziasztok!
Kezdem feladni a dolgot, a bal oldalon fix 12V-ra felakadt a kimenet. Átmértem mindent, végtranzisztorok jók, tápfetek jók, elégve nincs semmi, melegedni nem melegszik semmi, kh hiba nincs, LDR ledje aktív így az IC5 kimenetén 13V van, tápegység rendben van, és mégsem jó... Van valakinek tippje, mit csinálhatnék még vele?
