mataas ang reverse voltage ng diode na iyan. hindi kakayanin ng 1n4148 nasa 75-100v lang ito. palitan mo ng BAV21.

sinubukan ko nga ung in4148.nag karoon na ng sec voltage ang problema napkataas ng b+ 190v uminit kaagad ung b+caps 100uf/160v.gawa kaya yun ng diode na kinabit ko?o may iba pang sira sa primary?meron bang nabibili nung 1ss82 o kaya ung sabi ni master hertz na bav21?

master kaholito zener diode po kc yan kailangan exact ang repalcement.Gawin mo nalang cnabi ni master hertz,mataas na rin kc ang experience nila.Kung may pag-alinlangan ka subukan mong e search sa internet kung magkapareho ba ang 1ss82 at bav21..

Ganyan nga po ung board na ginagawa ko.d po ba mataas ung 135v na b+ sa 21 inch na tv?pano ko po mapapababa ito ala nmn syang variable sa board.open din ung r704 nya 1ohm ba un?inilipat ko ung diode na nsa harap ng reg na yan dun sa d705 tapos in4148 pinalit ko dun sa d707.hahanap pa ako ng 1N4937 at 1SS244 papalit ko sa in4148 bka gawa nun kya mataas ang b+.subukan ko din ung ru3c.salamat sa tulong mga master.
