lalong mag protect yan kung i float mo sa board,,,

dapat voltage check or resolder po muna kayo..ano daw po ba ang nang yari dito ayun sa tumer mo..

Ung supply ng vertical tama lng ba? Ano nakkita mo sa sreen.. or wala kc patay agad.

RhUNhA · « **Reply #10 on:** October 22, 2011, 06:42:27 AM »

direct sub mo muna yung VIC mo..then check kung walang open path sa supply nito
diode at ecaps check mo na din.
