salamat dito sa diagram master. masusundan ko na ang mga supply

sorry master. sharp pala. mali ang naipost ko.

bali ganito po kasi master. minsan umaabot ng 5mins bago magluko ang tv. normal lahat ng supply. nag planting nako ng mga capacitor. no good. pansin ko hindi bumabagsak ang B+ pag kapatay ng tv. para lang talagang may timer. pero pinagtataka ko paiba iba ang saktong oras ng pagkakapatay. minsan kasi umaabot ng 2mins lang o 4mins. nasubukan ko na din hinang lahat ng buttons. no luck pa rin

L70m ? ito yata ang chassis na may butas sa gitna ng board... kng anticipated power problem na normal ang supply mu sa PSU.. bka ngpoprotect ang unit mu during oscillation...
isaisahin mung i check ang mga potection circuit.

check mu abl resist, vert sect, xprot. suyurin mu din ang malapit sa butas kasi sa ganitong chassis may ginto jan.
