Samsung ue70tu TV nem indul
Sziasztok!
A szomszédnak bedöglött a tv-je még garos lenne, de nem találja a számlát.
Szétszedtem, már nem garos.
A hibajelenség:
Nem indul, a háttér világítás bekapcsol, majd újra ki, folyamatosan mint ha zárlatot érzékelne a táp.
Ha a kijelzőről lehúzok egy csatit a háttérfény folyamatos lesz.
Működés közben visszateszem a szalagkábelt rendben működik,kép is van egészen addig még ki nem kapcsolom.
Következő bekapcsnál kezdődik minden előről.
Lehet,hogy az egy éves tv-ben már megadta magát a táp?

Samsung CW25M064 ch.S16A alacsony a sortáp,videótáp, fűtés...Megoldva!
Üdv Mestekr! Kaptam a villámos S16A alaplap helyett egy kissé hiányosat (sorvégnél), egy csőhibásból...Áttettem a hiányzó trafót impulzuskondikat stb.A készülék indul is, de nincs kép,G2 és a videótáp is csak 100V, fűtés nem látszik. A sortápot nem tudom 125v fölé tornászni a 130V helyett...A stabilizált villanyok jók, távra reagál. Köszönöm
Samsung UE50nu7022k háttérvilágitás hiba?
Sziasztok!
Ki javított már Samsung UE50nu7022k 4k vagy hasonló tv-t Edge led hibával?
Ennek a hibája, hogy a kijelző baloldalon alul kb 10-15cm sávban nem világítanak a ledek.
Ott a kép kicsit feketébb egy függőleges sávban ami a képeken is jól látszik.
Itt láttam hozzá edge led bart ide haza.

[LINK]

A net szerint ez való bele, de inkább megkérdem a kollégákat.
2 db ledbar van benne, báronként 38 leddel. 540mm hosszban.( netes információ)
De attól félek, hogy a fényterelő is megéget, mert a bal alsó részén lehet látni, hogyan világítanak a ledek. De lehet, hogy ez ilyen???
Azt még hozzá kell tennem nem volt szerencsém Edge világítású tv hez.
Talán valaki meg tudja írni.
Üdv:

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 !
