Hi, my SAMSUNG UE40D5000 tv doesn' t work anymore. The red led light indicating that the tv is plugged is not powered when I plug in the tv. The original power board modem is BN44-00473B. I have checked the voltage on the connector to the mother board of the tv, and it was 0 instead of 5.3V or 13V on the different pins, with the fuse still working and no obvious overheated part on the power board and no bulging capacitor seen neither.
I have then changed the power board with a used one bought on ebay, which model BN44-00473A is said to be compatible. It has then worked perfectly 2 days until yesterday. This morning I had to move a little bit the tv, what I did very gently, and got really disappointed as I plugged it and didn't see the red led light on anymore.
Since this morning, the power board seems to be broken once more ( I have moved from my original flat 1 week ago and don't have a multimeter to check once more that the fuse is ok and what are the voltage on the connector to the mother board )
I am wondering if this new power board failure is just bad luck, 2 days after receiving this other power board circuit ( that is a used unit, not brand new) or if the mother board could have damaged it. In the first case I would send the power board back to the seller, otherwise I will probably give up as I don't have time and skills to repair the tv.
My question is : do you think the mother board or another unit connected to it, can damage the power board ?
Thanks for your help and answers !

Egy áramkimaradás után kezdte produkálni a hibát.(néha megy órákig is, de ha valamit kapcsolok a távon rögtön elkezdi ezt a végtelen ciklust) Nem vagyok szakember, hobbiból azért forrasztgatok ezt azt.Felhívtam egy szervizt akik akár 40 ezer Ft. körüli összeggel riogattak, tavaly T-cont cseréltek 40-ért.
Már soknak tartom évenként ennyit a tv-re költeni. A kérdésem arra irányulna, hátha valakinél történt már ez a fajta hiba, és tud tippet adni melyik a cserére szoruló alkatrész.Így talán megtudnék házilag is birkózni vele.
Köszönöm!
Sziasztok!
Van kettő KS3 elktronikám. Egyik 100 a másik 50 HZ-es. Az 50-es villámcsapott, tuner és VDP3120c3 cserélve a 100-as LA7845 cserés volt. Jelenleg mindkettőn van kép és hang, viszont ugyanazt a hibát produkálják. A kép hordós, OSD függőlegesen fut. A 100 HZ-es
panelba egy üzemképes készülékből már átraktam a procit, opció IC-t, digi-t. Tápok jók, OSD továbbra is fut. Help! (A korrektor IC-t és tranyót is cseréltem újra.)
Köszönettel, TO.
