Samsung UE40NU7120 TV villámkár, kiégett biztosíték, zárlat a primer körben
Sziasztok! Egy ismerős hozott egy UE40NU7120 Samsung TV-t. Többek között neki nem tetszett, hogy a közelbe becsapott a villám.

BN9646783A alaplap van benne. Bizti kiment. A 450V-os kondi jó, diódák jók, de a kondin 1Ohmot mérek. Varisztornak kutya baja. De repül a bizti.

Kérdések. A Fet a hűtőborda alatt van vagy a két taknyos az? Ez a szalagkábel ugye úgy bontható, hogy felnyitom a rögzítőt?

Merre induljak? Esetleg valakinek rajza nincs hozzá?




 
Samsung S16A nincs készenléti állapot
Üdv Mesterek! Hoztak hozzám egy a címben szereplő sík csöves szörnyet.A tulaj külön hozta zsebben a belőle kiépített irf630-at,mondván,hogy már volt szerelőnél,az azt mondta hogy ez a hibás.Hát a sasszén volt még gond bőven.Az L405 égett,a D404 zárlatban,R406,419 égett.Cseréjük után és a szokásos impulzustűrő kondi,és a szekunder oldali mérésre rossz elektrolitok cseréje után a táp műterheléses indításánál ,a táp indul,megjön a feszültség,de táp kapcsolgat inog.Primer oldalon minden puffer cserélve,a két elektrolit kondik szintén,a diódák mérésre jónak tünnek. STRW6750 power ic van benne,ezt nem cseréltem mert nincs itthon.Készenléti led nem világít.Az UOC- tápfeszei megvannak,bár a táp kapcsolgatása miatt ez is inog. Ha van valakinek ötlete,miért nem áll be a táp ossza meg velem legyen szíves mert már két napja nyűglődök vele.
SAMSUNG UE40D5000 power board no more working
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 ! 
SAMSUNG LT32E310 monitor/Tv bekapcsoláskor 5-öt villog a stby led
Üdv a Szakiknak!

Adott a fenti címben szereplő Tv. Bekapcsoláskor 5-öt villan lassú ütemben a készenléti Led. Tudja valaki, hogy ez mit jelent? A készülék amúgy működik, de régebben nem csinálta, -olyankor bekapcsoláskor csak 1-et villant.
(Csináltam róla videót is, de nem tudom hogyan tudnám ide betenni, mert egy google drive linket sem enged betenni.)


Köszönettel, Gyula
