pg tumunog yan ay nagpoprotect ang unit.. check for possible reasons na pg aactivate ng protection...

pg di nmn tumunog ay focus on amp section... lalo na ang sound ic.. "STK4152II"
check mung maiigi ang supply nya.. base nlng muna tau sa datasheet nya.. kng buo ba lhat at hndi nka mute
check mu na din ang mga resistor nato kasi lagi yang nsisira


sunod mu nmn ang tranny mlapit sa ic

ah dual spst lng pala yan sis.. pwde ng di na tnggalin sa board iyang relay mu kng mgba bypass lang... ipag short mu lng ang mgkbilang side. "red lines sa sample picx"



uu nga pla sis.. safety precaution tau lagi.. wag munang ikabit ang spkr. monitor muna sa ac voltmeter ang output ng amplfier sect mu. set mu sa ac 50v (red) ang multitester. dpat nag vivibrate ang pointer "gumagalaw" interms na normal ang running nya... pg super steady nmn.. both ac & dc voltmter. wag na wag mung ikakabit ang spkr baka masunog.. bka kasi my DC out ang Amplifier section mu.. kya di gumagana ang relay na bnabanggit natin sa taas "ngpoprotect"...

pa ot: psenxa na sa drawing (^_^

wala ka bang ecap na sira?
tanong ko lang, bakit kailangan short mo pa ang relay?

I doble check ko nalang Sir Danny kung walang ecap na sira. hindi ko sure kung nag protect ang unit, pero kahit hindi naka short ganun din wala din.
