bago poh fbt nito kahit walang fbt kalas laht nasa 139 b+ nya...
may 5volts sa pin 8 in memory nagkakaroon ng 8.something sa hvcc ng jungle during power on nwawala yung led indicator indication na nagpower on na may oscillation poh 5vols ac sa base ng hot....
kaso bakit kaya walang 12volts at 24volts galing ng fbt....wala din heater at screen psu poh kaya to anu kaya normal b+ nito?
any mapa poh?kasi yung hot nya ay d1554 yan ba tlaga orig nyan hot galing din kasi sa ibang tech to parang kapos kasi yung paa nagdugtong na lang ako ibig sabihin di ito yung orig na hot nya?

Sana may mapa nito dalawa na kasi nasira nitong hot okey naman sial parihas yung lumang fbt kasi singaw lang using fbt tester okey nman sila parihas magkaiba nga lang ng amp yung bago at luma ibig sabihin mataas tlaga b+ nito kaso
Pinalitan ko na to
Regulator,
Photocoupler
Tl431 at lahat ng mga resistor sa feedback section 4X ko ng tinest using digilta at anlog tester
Filter ng secondary palit narin 47/160 at 100uf/160
