Becker BE0729 kér kódot de nem reagál semmire.
Szervusztok!
Van egy fent nevezett (BE0729) készülék ami kéri a kódot de semelyik gombra sem reagál csak a bekapcsolásra.
Eddig be vette de most mintha lefagyott volna.A kérdésem meg a kérésem az lenne ha valaki már találkozott ilyen problémával és azt meg osztaná velem azt nagyon megköszönném.
Várom a megtisztelő válszotokat.

AUDI Bang & Olufsen Erősítő ( 8T0035223T. Fóliázáskor beázott.
Üdv Mesterek.

Bang & Olufsen  8T0035223T. Erősítő sikeresen elázott egy fóliázás során.
A neten kutatva igen sok rendesen szétégett erősítőt láttam, de millió változatban.
Javított valaki már ilyet , esetleg bekötési , vagy netán kapcsolási rajza , van valakinek?
Nekem a 2db táp FETT lett zárlatos , meg néhány a körben található ellenállás és Kondenzátor bánta.
Csak a rádiót hozták be , autó nincs a közelben.
Autó nélkül el lehet indítani?

 
Leyland AM/FM Car radio - no FM

This radio is to a 1970's MG/MGB vehicle. Its using an older 14 Pin DIP IC to
do the FM stuff, its marked T2D. Cross ref comes to a NTE723.

If I put my metal probe on pin 9 or 10 (detector) I can hear a local FM station playing,
but the tuning has no effect.

I have 100 ohms from pin 9 or 10 to gnd. Pin 3 is seen directly tied to gnd, and pin 4 also reads short to gnd
and there is no DC volts on it also no dc volts on pin 5. I can see no dc volts on any pin I probe. Is the IC bad?

Its not getting warm for short and current draw on the PS is minimal.
