PS2 játékok
Üdv Egy csóró ismerősöm kért meg nézzek utána lehet e másolni illetve másolt játékot kapni a fenti játékhoz. Mivel szerencsére még nem volt dolgom e szörnyeteggel egy kis oktatást kérnék ebből a témakörből. Annyit tudok, hogy ezek a masinák már DVD filmet is lejátszanak és a régió kódra oda kell figyelni. Gondolom DVD és CD lemezt egyaránt elfogadják. Köszönettel Laci
Battery charger with EM78P41 IC
Working on a speed charge battery maintainer for small engines battery. Heat sink had (2) S2025R T0-220 type components on it. Seems they are an SCR and I have 57 ohms on 1 and 3 pin, so seem they are short. Cant get these anymore but installed S4025R which seems to be better replacement. Before replacing, heat sink seemed to be really hot after replacng on on 
board 10 amp automotive slot type fuse, so seemed these SCR were bad, getting hot woth no load.

Standby LED not lighting with new SCR's installed. Old ones did not have heat sink compound on them, so I used some to better transfer heat. I saw the input of the 7805 1 amp
regulator IC has short, so removed it, and its not shorted, but the feed to it comes from the IC chip on board, a EM78P41 BWD20J. Data sheet for EM78P41 is online. They have pin 16 going to pin 1 of the 7805 regulator. Actual reading on pin 16 to ground is 2.5 ohms. I suspect this IC is shorted output. Is there chance to replace IC or is this repair finished?
Beltéri egység tápjában található IC beazonositása (megoldva)
Üdvözletem mindenkinek ! Olyan irányú kérdéssel fordulok a tisztelt tagság felé , hogy a tv -m beltéri egységét meglátogatta egy nagyobb feszültség (villám) mint amit elviselt volna ebből kifolyólag a táp részben található IC megadta magát és elszállt a szó szoros értelmében mert teljesen lerepült a teteje , ezáltal nem lehet elolvasni a típusát . Amit ki tudtam olvasni az annyi hogy a felső sorban ezt találtam : "1200P60 " , középen ami megmaradt :"....CL , és alul ennyi látható :"....42G " Az a kérésem ha valaki tud a be azonosításban segíteni azt nagyon szépen megköszönöm .
