Samsung LE23R81B Nem kapcsol be
Sziasztok!

A tv-ben levő tápegység típusa BN44-00158A.
A panelen amit találtam hibát egy púpos elkó kondi,CB852-1000 uf-os kondi és egy KA431 sönt regulátor,ami az oxidáció során a lábai elrozsdásodtak.A hibajelenség az,hogy a PFC kimeneten a 380V helyett csak 320V-ot mérek,az 5,2V stby és a 12,24 Volt nincs meg a panelen.A biztosítékok nem szakadtak,összekötve a táp panelen a PS-ON és 5V stby-a feszültség mérésekor is hiányoznak az 5V,12 ÉS 24V.Cseréltem az FL922 IC-t is a hibajelenség továbbra is ugyanaz.Van ötlete valakinek ezzel kapcsolatban,találkozott már ilyen hibajelenséggel?

Köszönöm előre is a segítséget!


 
Samsung TV GU55AU7179uxzg Does not Switch on suddenly
Hello everyone,

i am new to the forum and i would like to save a TV from the dumpster. I figured out that IC207 is broken on the mainboard of this TV. Does anyone have a schematic for these kind of TVs or even have the same and knows what IC this is? I presume it is a voltage regulator. The TV is totally fine but does not turn on any more. The power supply is perfectly fine. I desoldered this IC as it was getting very hot and was the only issue i found.

Thank you!!!

Samsung UE46D6100SW kijelző csíkozódás
Sziasztok.

Adott egy Samsung UE46D6100SW, mely rendszerint a csatolt képeken látható hibát produkálja. Egyelőre ennyit tudok: "Bemelegedés után eltűnik a hiba." Letöltöttem a szerviz manualt, de a csíkozódásra utaló javítási útmutatót nem találtam. Érdemes nekiállni a hibakeresésnek, és ha igen merre érdemes elindulnom és mérnem?
Köszönöm!
