    Default Kathrein UFS 910 - Damaged Power supply

    Pentru cei care mai au acest receptor
    Personal am dat la o ruda de al meu la care a mers vreo 5 ani non stop fara sa fie orpit si s-a dus cateva condensatoare si un integrat ... si am avut nevoie de lista componentelor de pe sursa ...

    Diese Bauteile sind auf einem Netzteil einer 1W Version Bj. 2007.4.23 R 0.3 zum finden.
    Liste wird stndig ergnz. Wenn jemand noch andere Details hat dann bitte posten.

    Thumbs up

    daca tot santem la capitolul de defecte am gasit pe net acest material care sper sa ajute pe detinatori receptoarelor Kathrein UFS 910

    I got similar issue: Red light only on power on, no serial port response, no LAN initialized.
    Spent all night digging forums for solution, trying different application etc.
    Finally opened my box and straight away noticed capacitor C2 expanded.
    I did not have the same spec one, and at 3am was difficult enough to search for right part, and I put absolutely different one but logically more or less suitable for stabilization circuit.

    Some notes for new starters met the same issue:
    1. UFS910 RS232 null-modem cable: effectively there are only 3 pins used for this device: 2,3,5. If you have not damaged cable and pin 2 on one side goes to pin 3 on another - you have right cable.
    2. You always can test your PC's serial port output by loopback test: interconnect pins 2 and 3 in the port (better in the pc to UFS910 link cable on the ufc910 side) and run hyperterminal. In the hyperterminal file->properties->Settings->ASCII Setup... select box "Echo typed characters locally" and OK.
    after you back in the hyperterminal's main window you can type any characters and you will see them, if your serial port is ok, and pins 2 and 3 shorted together characters will appear twice each. It is mean you have no issues with PC side comms.
    3. all the apps you can find: kathi up, KCC, AFF recovery... they all do absolutely same things in terms of serial communication.
    If you have no response from the device in hyperterminal - this apps will never help you. (kathiup for example does something and consequently updates the status even without serial port linked).
    4. Capacitor C2: original 4700uF 10V, fitted (incorrect but works) 1500u 250V. I would change it for ~4700u 16V (I think it V rating is the issue).

    Next time my UFS910 will die I will collect full info about PSU outputs needed for quick diagnostic.

    succes tuturor

    am pus mana pe un Kathrein UFS 910
    adus din germania de catre cetateanul haules-baules moo (sefu ma jur pa copilasii mei ca merge ) adevaratul a spus 100%
    a luat-o din prima ,are firmware de fabrica
    voi schimba condesatoarele electrolitice defecte cu alte noi +un ventilator de racire in interior , e si pacat de acest receptor cu un numa emblematic
    Kathrein UFS 910 isi merita o noua sansa la viata

    Merită bătaia de cap, succes!

    Putina atenție de unde cumperi electrolitici, am avut surprize neplăcute de-a lungul timpului; de multe ori prefer condensatori proveniți din recuperari, verificați și sortați cu ESR-metrul.
