Üdv mindenkinek! Mint a cím is mutatja, halott a kis 32-es. A táp primer oldalán áll a 310V=, a szekunder oldalon csak egy 5,2V mérhető egy diódán, de az sem jut el a csatlakozósorra,más fesz nem jelenik meg. Stndby led sem világít. Amit tudtam a tápban körbevizsgáltam, szakadt vagy zárlatos ellenállást vagy diódát, hibás kondit nem találtam. Valakinek tapasztalata (táp, main, inverter vagy más) ???????

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 ! 

I have LCD LG 47LD450 model . The problem is the power supply - EAX61289601 / 11. No full esqema this power supply , already identified several burned Components that can not know the reference. Someone can help me? Components list burned: R230 R218 Q201 IC0201 R217 D605 R615 R617 R621 Q602 Q601 Best regards Nuno

Üdv! Lenne ez a CCFL Samu. 
Azt csinálja, hogy kb. 2 sec-enként folyamatosan indítja a pw on a tápot, majd leveszi a 3,3V-ot. Tehát, indít, (3,3V)és leáll. A stby led ennek ütemében villog, de semmi más életjel. Ha összekötöm a stby és pw on-t, akkor a mainon megvannak a folyamat ábra szerinti feszek https://elektrotanya.com/samsung_le26s81_le26s86_le32s81_le32s86_le37s81_le40s81_le40s86_bx_bd_chassis_gja26-32-37-40-46seu_sm.pdf/download.html#google_vignette Mi lehet? Ko a main? Kösz
