Sziasztok!
Most került hozzám ez a készülék, a tápegysége jó, 14V 140V megvannak, távval indítva a piros led meghalványul, de más nem történik, nem indul el a sor. A sormeghajtásban a két BC-ét cseréltem, de ott sincs meg a sorjel. A procinál eddig csak 3,3V, és 3.9V-okat mérek, nem kellene 5V-nak is lenni, a rajzon szétszórva vannak meg a feszültségei. Valami táp hiba, vagy a proci?
Sziasztok!
A fent említett tv került hozzám aminek se háttérvilágítás, kép, hang nincs. Bekapcsoláskor a TV ledje felvillan kb. 5mp-ig utána kialszik, a tápon mért feszültségek rendben vannak, viszont az alaplapon mért egyik feszültségel gondom van. a képen amit csatoltam az alaplapi feszültségekről minden feszültség rendben van kivéve egy feszültség ami a L701-es tekercsen kellene legyen +1.5V, ez a feszültség nincs. Zárlat van a +1.5V kimenettel a testre. A rajzon lévő alkatrészeket ellenőriztem de egyik sem okoz zárlatot, létezik hogy a kis U703-as zárlatos és ez okozza fent említett hibákat és nem engedi a TV-t beindulni?
Előre is köszönöm a segítséget!
Üdv.: Attila
