Patulong mga masterz, auto shut off sya after 2 blinks.

Ito info:
may supply ang B+ = 115v, may supply din to vertical = 11.5v.

mga ask ko po kung normal pa ung voltage sa regulator pin#1 na 324v sa schematic is 226V lng.

Thanks in advance mga masterz....

TS.. tanong ko lang nakakapag Oscilate pa ba ang flyback bago sya mag shut off? may raster ba sya bago mag off, Check mo yung B+ voltages nya during mag oscilate ang Flyback, also try mo muna paganahin sa 110V.

Sis meron oscillation kasi may nasusukat ako sa secondary bago mamatay at stable ang B+ na 115v.

pag nag shut off, wala na din bang ilaw yung LED standby?
