nakagawa na ang technician ko ng ganito
pero sa goldstar na brand. checkin mo daw ung peripheral
parts sa may jungle IC, yung sa gold star daw he remember
na coil daw ang sira, it is used for processing tatlo daw ang coil
isa or dalawa daw ata ang pinihitan niya then ung isa pinalitan niya,
so try mo baka same cla ng design ng goldstar.
also, my own suggestion naman, if ever na walang nangyari
cmulan mo na mag signal tracing, Audio/Video na lang ang gamitin mo
scope-in mo na lang kung saan nawala ang signal mo.
I am assuming na ok lahat ng voltages mo.
hope this helps. paki balitaan mo na lang ako sir if ever
thanks

sir dan,
i already did it..sa av mode ako nag start..cheking my scope may input but no output..i hang the base ot transistor that switch between av and tv mode at napa signal ko sa av..pero di kc dapat ganon ang mangyari..dapat talaga ma locate exact problm n2.this s a big challenge for me but definitely i love this trouble for future referrence..is there any added info?

gusto ko kasi makita ung sinasabi mo na tranny kung saan at
ano ano ang mga nakakabit. nde kaya naka mute yung sgnal mo?

hmmmm.....  napaka-complecated nmn ng trouble  pero honestly challenging

sana mapost mu yung diagram
para ma-trace natin ng mabuti........
