« on: December 07, 2011, 03:30:20 PM »
mga sir good pm... meron akong problema sa JVC AV-P21X flashing lang yong standby led... sukat ko mga voltages ang standby voltage sa B+ is 78V, sa system 5V, pagpindot ng secondary power B+ goes to  135V but after 2 sec. goes back to 78V, yong 5V sa system stable naman, yong mga voltages sa secondary pagpindot ng secondary power nagkaroon siya ng voltages 5V, 9V at 12V pero goes to zero volts after 2 sec din... action taken resolder sa system, chroma, CRT, all possible cold solder joints, replaced all ecaps in primary and secondary, replaced vertical IC at regulator pero ganon pa rin... need your expertised mga sir...
it's not how much what we have but it's how we used what we have...
