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 !

Sziasztok!
Ennek a tvének a következő a gondja, hidegen jól működik, de ha bemelegszik akkor kikapcsol készenlétbe. Visszakapcsolva újra üzemel pár percig, de amikor kikapcsol akkor előtte zenél , nem tudom ez fontos-e? Eddig cserélve lettek a szabályzó elkok a tápban, és még a táp ic is. Levett hátlappal sokáig jó, de felcsavarozva már hamarabb jelentkezik a hiba. Nem tudom hogy ezeknek ez a hiba típus hiba szokot-e lenni, vagy valaki találkozott már ilyen hibával?
Tisztelt Szakik!
A tévén behangolva az adásokat, a hang sistereg. menüben megnézve a hangnorma beállítást, kérdőjel a hangnorma!!!! kiválasztva a megfelelőt a B/G ; D/K közül, utána minden rendben. de ha megint hangolás történik ezt újból be kell állítani! programhelyenként!
Kérdés: ilyen a készülék? vagy szervízmenü és gyári beállítás visszaállítása? vagy egyéb?
tisztelettel
