Dupa schema de la sasiul KS7A este cam mica tensiunea specificata de dvs doar 103v pt linii . pe schema apare 130v!! Cei 5v ii aveti in secundar la sursa??? Ati scos receptorul de infrarosu afara?? Ar trebui sa mergeti invers ,de la ledul de st-by si receptorul de infrarosu spre procesor sa vedeti ce si cum?!?!
