@TS cinemaborg eto tama?

mostly laganap ang fake na power reg nyan (stk73907-t). kya minsan lagi tlgang nasisibakan. halos wla na akng mkitang orig nyan sa merkado ngyon except sa suking tindahan pngkakatwalaan tlga "kilala ang owner ng tindahan" or mismung service center ng panasonic at sharp nlng bumili



on topic:

mraming way para atleast mareduce ang chance ng pgkasibak ng Power reg. always check the peripheral parts ng Reg.. lalo na ang big mylar caps sa likod ng SMPT, check mu ang mga resistor lalo na sa biaser, check ang optocoupler, palitan ang error amp SE120, Cguraduhing hndi ngluluko ang B+ mu.. monitor mu both 110V & 220V. nglalaro lng dapat yan sa 120-125V. then check na din ang FBT. pgyan mga yan ay nagawa na at same pa rin... i built in mu nlng ang 110V trafo sa loob ng tv case.
