tanggalin mo muna ang load ng b+ mo sis para ma-isolate mo ang lugar kung sa primary ba or sa load ang problema,monitor mo ang b+,pag ganyan ang trouble ginagamitan ko ng bombilya para di sayang ang pyesa,ic601 ba ang regulator nito sis

tama po ic601 ang ic nito

sa ngaun po binaklas ko ung main board sinusuri ko p po lahat ng pyesa para sure n...

experiment narin tsaka pinagaaraln ko rn po lahat ng pyesa para matuto dn.

may parang transistor ang pyesa dyan pero dalawa lang ang leads, yan yung fuse ng +B.. hang mo yan mula sa filter cap na galing sa chopper mo.. duda ko mga diode sa paligid ng PSU ang prob nyan.. check mo na din timing capacitor sa may primary at baka shorted (mga blue ceramic caps).. kung hindi kasi tama oscillation nyan, putok talaga yan.. update na lang po..

may data ako ng STRS5741 tinatry ko ipost kasama picture baka mkatulong sa troubleshooting kaso hindi ako marunong

mga sis pano ba magpost ng picture?

mcleod · « **Reply #52 on:** February 21, 2012, 11:14:06 AM »

kapehan na ba ito? baka yung bridge rectifier mo leaky. main filter capacitor kahit good looking pede manibak ng HOT.
