Sziasztok! Adott a témában jelzett, ívelt led TV. Tulaj elmondása szerint egyik pillanatról a másikra kikapcsolt és azóta nem lehet bekapcsolni, csak villog a stand by led. Még nincs nálam a tv, de előre érdeklődnék egy kicsit, hogy hátha valaki találkozott már ilyen hibával ennél a típusnál? Ha nem, vagy nehezen javítható, akkor inkább el se hozom. Első körben tápra gyanakszom.
Complaint was no display, confirmed and I saw
this series USA model is very prone to backlight failure, so
ordered (8) new strips. Opened up the TV, and am testing the old ones. So
far all the ones on the right side are lighting up ok,
the set of strips connected to them via the connector side with the plugs
are not lighting up at all, even when I supply power directly
to the pins on that side.
I took out a set of the new strips, connected them together and tested, and
they are doing the same thing...whats going on? Thought these were all in
parallel.
If I separate the strips, the one with the connector plug seems to not
light. I have not gone through all the
new ones yet to test. I suppose they could be defective but strange how all
the ones in the TV on that side are not lighting and the others are.
Anyone have an idea whats going on here?
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 !
Tisztelt Szakemberek !
Téma szerinti TV-nél ( SAMSUNG CZ-25D83N ) pár nap alatt a képen mindent piros "fátyol" boritott el, pl. a fehér ing enyhe rózsaszín, az arcok piros pozsgásosak. Lehet, elment a zöld szín ? Élesség, kontraszt arány, fény, méret rendben.
Sajna a képen nem jól jön ki, de a fehér blúz árnyékos részein látni, hogy rózsaszín. A valőságban sokkalta zavaróbb a rózsaszín fátyol.
Mi a teendőm ? Balta vagy forrasztó páka ?
Várom szíves válaszukat.
Üdvözlettel, patyóbácsi
