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,
Ócskapiacon vásároltam a címben jelzett erősítőt. Tisztítás közben vettem észre, hogy valamiért hiányzik belőle az egyik puffer kondenzator (10.000uF/50V). Vásároltam egy ugyanilyen kondenzátort a TME oldaláról. Rubycon gyártmány. Viszont nagyon gyanús, mert a mérete kb 1cm-el kisebb az eredetinél, pedig 63V-os. Milyen kondenzátort érdemes venni és hol? Egyáltalán érdemes több pénzt költeni rá? Szerintetek a meglévő pufferkondit is érdemes egyúttal cserélni?
Köszönöm!
Endre
Szervusztok!
Van a fent nevezett készülék aminek a FM része nem működik (Sony tux-032 tuner van benne) AM-en szól,FM-en egy pillanatra beindul aztán leáll. Ha valakinek van valami sejtése erről a hibáról akkor segítsen.
Várom a megtisztelő válaszotokat.
Üdvözlettel!buszosgyuri
