    SAMSUNG UE55H6290SS

    Hallo zusammen! Das oben beschriebene TV-Gerät zeigt, wenn es eingeschaltet ist, für ein paar (5?) Sekunden am rechten Bildschirm-Rand nur die Zahlen 47, 48 und 49 untereinander. Die 48 in der Mitte ist etwas größer. Dann schaltet sich das Gerät in der nächsten Sekunde aus und wieder ein ... Dieser Kreislauf ist endlos. Mit der Fernbedienung kann nur ein/aus bedient werden! Sonst nichts. Wenn eingeschaltet, kann ich durch Löcher in der Panel-Rückwand sehen, dass der gesamte Bildschirm aktiv ist (zartes blau), aber kein Inhalt - nur die 3 vorhin ​beschriebenen Zahlen. Ich habe an der Netzplatine BN44-00711A an einem beschriebenen 5V Messpunkt 4,6V gemessen! Die 13V Grundversorgung stimmen beinahe mit 12,8V. Der Übertrager (Trafo) zwischen hot und cold wird ziemlich warm (zu warm, um ihn anfassen zu können). Kann mir jemand bei der Suche nach Schaltplänen helfen - zumindest für das SMPS (Schaltnetzteil) Nr. BN44-00711A?! Vielen Dank! Josef

      Muss ich mit Diah einstimmen. Entweder den EEPROM neu programmieren, oder die Hauptplatine austauschen.
      remember this is a English forum!

        Thanks guys for your inpputs!
        I worried about this diagnosis ;-) ... I do not have (good) knowledge of programming an EEPROM and I don't have equipment (tools) to do it.
        I'll see how much it costs to replace the main board. I'm grateful for you offered help!
        Regards, Josef

              Hallo all! I took a look at ebay for the motherboard (mainboard): - almost met, but no exact match.
              Motherboard needed:
              BN94-07774H --> for Samsung UE55H6290SS

              I only flound similar ones at ebay:
              BN94-07774C --> for Samsung UE55H6200AK
              BN94-07774D --> for Samsung UE55j6240
              BN94-07775G --> for Samsung UE55HU7200U
              BN94-07775H --> for Samsung UE55HU7200U

              Found at indiamart.com: Model UE55H6290SS Samsung LED TV Motherboard at Rs 6499.00 | LED TV Motherboard | ID: 2853235079112 (indiamart.com)
              The only description here: "Model UE55H6290SS Samsung LED TV Motherboard". No label of this showed motherboard this mentioned. - BUT the describtion for the Samsung TV is the correct one!!! At a shown image this mainboard looks to be the same as my example here!!

              QUESTION:
              * What would you recommend? Trust the one from indiamart? If there is no function, I doubt to have allowance for return for credit ... but - no risk, no fun ;-).
              * Or is there any particular experience, that one of the ebay-boards will fit? I also doubt.

              Thanks for your opinion!
              Best regards, Josef

                  The next day I received your information, I opened the eBay link - the board was already sold! A pity.
                  I searched a lot ... found another BN41-02156 described for a UE60H6270. Only the board number is missing (should be BN94-07774H). Samsung UE60H6270 Mainboard BN41 - 02156 | eBay
                  Can this board (described for UE60xx!!) also fit my UE55H6290? Thanks again!!
