halihó, hoztak egy kenwood kdc-5090ry tipusú autórádiót, amely a kijelzőn bekapcsolás után WAITING 4 (gondolom) hibakódot ír ki. Az elért forrasztásokat átforrasztottam, majd egyszer bekapcsolt. Azóta akármit csinálok vele, hiába, csak a kijelzön lévő hibakód (?) van. Estleg ha tudtok valamit erről, megköszönném.

Hello, I am in a repair KENWOOD KRF-X9995D.
Let me know if anyone is aware of how to reset the processor.
That is about a year ago I had the same problem with another amp of the same model!
So this is the second unit can not repair!
The main flaw is that the accumulation of around 1F 5.5V had spilled acid. was also in the same thing happened! ie it shows mute, but going into test mode, (having pressed the key "INPUT SELECTOR DOWN" and "POWER", the analog input works (but only in TEST).
Any help?
Thank you
Sziasztok!
Nem tudom mi lehet a gond az erősítő 5csatornás equaliserével.2 db M5227p ic vel van felépítve.Bekapcsolt EQ állapotban az erőlködő egyáltalán nem szól,kikapcsolt(defeat)állásban meg szabályoz(lefelé) az adott EQ frekvenciákon a potit felhúzva gerjed egy szint után.Rajz kellene mert így elég áttekinthetetlen a jel útja.Hanggenerátorral próbáltam követni de már kissé belefáradtam.
Üdv!
