Toshiba 25 surplus t.v standby mode only
« on: June 04, 2011, 12:49:58 PM »
mga master patulong sa newbie, pag on ng t.v may tik sound then mag light ang standby led (ginamitaN ko na rin ng remote same po ang nangyare nag tik sound only). Meron normal voltage sa filter capacitor but no B+. Meron input sa StrS5041 same voltage ng filter cap, ask ko lang if this is the culprit kase wala me makuha na any output voltage? Maraming salamat po If meron po kayo flowchart what to check next na ma share sa akin. ??? ??? ???

Mga master update po Toshiba 25 standby mode only

remove HOT  nagkaroon ng 115 volt ang B+
voltage sa chopper transformer secondary 50 volts
still tv at standby mode

check ko po ang hot transsitor shorted po ata sya kase ang palo ng analog tester sa base-emitter and emitter-base ay zero.
Ask ko lang po mga master ang diagnosis nyo. maraming salamat
