Innowert plazma TV pukkant, majd buffer csere után tápzárlatos (Samsung S42SD-YD05 PDP) - MEGOLDVA
Na szóval adott ez a TV. Az egyik Y buffer füstölve távozott az örök vadászmezőkre. Y-SUS-on elvitt egy fetet meg pár kondit magával. Külföldről beszereztem egy tesztelt jó Y puffert 7000 Ft-ért, kondikat fetet újra cseréltem, bekapcs, a TV indult, de színkavalkád volt a kép (full fehér és absztrakt színezetű kép között "hullámzott" folyamatos átmenetben). Rámértem a tápkra, VS alacsony volt, maximumra tekerve a beállító potit épphogy 170V volt, amikor ki is kapcsolt a cucc. Biztosíték elment, tápban az egyik ellenállás szakadt, két fet full zárlatos, ki is vannak nyílva. Sajnos így most nem tudom hogy a két fet volt alapból gyenge, vagy valami túlterhelte még a Y-SUS-ról. Valakinek valami tipp? Most próbálok új tápot vadászni bele hátha van valakinek. Esetleg valakinek volt már ilyen gondja, van valami tippje hogy mi a búbánat lehet még problémás? Előre is köszi az infot.

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!!!
