Sziasztok!
A fenti tv bekapcsoláskor vízszintes csíkkal indul,csak egy pillanatra jelenik meg utána minden jól működik legalább is látszólag. De elmarad a szokásos bekapcsolási metódus. Mi lehet az oka?
Üdv: Wolf
Üdv. a Kollégáknak!
Az emlitett készülék mainboardjának a kapcsolási rajzára lenne szűkségem, ha valaki tudja, hogy milyen módon tudnám beszerezni, nagyon megköszönném. A készenléti 5V bejön a tápból, de a belőle származtatott 3,3 v már hiányzik, mert zárlatos a 3,3-as vonal. Amit tudtam, leellenőriztem kapcs. rajz nélkül - és ezidáig minden rendben - de valamit kihagytam, mert elég nehéz lekövetni az áramkört, most már nem tudok továbbmenni rajz nélkül. Az alaplap kódja: BN41-01958B, a display tipusa: SAMSUNG CY-HF400BGSV1H.
Előre is köszi a hozzászólásokat.

Képcső csere után próbálom beállítani a képgeometriát, viszont a képszélesség-lehetőséget sehogy sem találom. Vagy én vagyok vaksi ? :(
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!!!
--> I corrected it. Thanks for pointing out!
