ang Jungle ic ay pamilyar din sa tawag na chroma ic dahil marami siyang circuits sa loob, kasali na ang video at sound processing at laging kasali ang line at frame oscillators plus ang sync na rin. sempre ang vertical at horizontal sync. iba iba ang numero ng jungle kaya dapat maging pamilyar dapat kayo nito.



@fire kong nagbibigay ng ibang supply ang flyback mo para sa screen, focus, abl at iba pa. baka nga sira ang winding ng vertical mo. subukan mo ngang gumamit ng ibang power supply

bago mgpalit ng vertical ic dpat na check nyu na ang mga supply nya. dapat present ang mga yan bago humatol..

kng wlang lumalabas na AC voltage sa FBT (for vert.) at siguradong nag ooscillate ang fbt ay sira nga iyang flybak mu..


pa OT: nalilito aku sino sa inyu ang TS ?
