Sharp LC32D44E nincs hang se tunerről, se av-ről
Üdv Mesterek! Egy LC32D44E-t javítottam a hátterében kisebb "pirotechnikai bemutató" volt. Lámpák kicserélve, háttér rendbe rakva , lámpahiba reset...és utána nincs hang, se tunerről, se scartról. De, a hangvégfok jó. Valami opció gond lehet, de mi?
SHARP LC32DH500E lcd tévé tápegysége pulzál.
Sziasztok!
Nevezett készülék (legtöbbször) bekapcsolható, pár percig működik, majd letilt. Elkezdtem méricskélni, de valahol (szokás szerint) elvesztettem a fonalat, vagy elvittem magam az erdőbe. Eljutottam odáig, hogy a tápegység kimenetén minden feszültség pulzál amikor nem  működik a készülék. Hűtésre/melegítésre nem reagál, de ha hagyom kihúzva 12-20 percig, akkor vissza tudom kapcsolni. Kivéve a tápot és kényszer indítva szintén pulzálnak a feszültségek, miközben a PFC (elkón mérve) stabil. Egyszerűen nem látom fától az erdőt?
Köszönettel: Kiss Zoltán
