Kabit mo sa cable strap ang black probe mo. Then hanapin mo yung pyesang nagpapabagsak using continuity test. Unit power off and drain.

cge sis try ko sis,pero wala akong pamalit nito...tapos nagkaproblema ito may hizzing sound sya..kasi may hinang ako na resistor tapos nagtry ako na i-on sya, umakyat yung b+ pero bumaba ulit balik 36vdc sabay hizzing sound...nagdududa kasi ako sa resistor na tinanggal ko parang change value sya at diko malaman ang exact value nya kasi medyo burado na ang kulay..kung may mapa kayo nito sis sana may mag-ambon...

just specify the part number ng resistor baka part yan ng feedback o secondary loads

chassis px1 - 3 yan. di ko lang ma distinguish matagal na kasi ang model na yan. subukan mong pm si Sir. baka remember niya pa. sa panasonic naman siya nag work dati. puede mo download ang mx5 para may guide ka na. parepareho lang ang mga yan. pang replace ang mga Q reg sa C4804 at C5223

alvinquimbo wrote:Ito ang resistor na tinanggal ko:




for ground isolation yan. naka parallel sa c840. 8.2M ang value. maaaring madumi ang board mo kaya wala kang isolation sa Hot at cold side. linis muna gamit ang lacquer. hanap din ng loose connection at crack sa board.

hindi yan ang chassis. yan ang eboard number niya

Sorry. my mistake.. for ground coupling pala yan. pag yan tinanggal. floating ground ang mangyayari

mga ganyang board nga master ang sirain ang vertical. master na try muna magpalit ng vertical? try mo rn iyong mga turo ni master na direkta ng 5v sa switch. epektib din yon.
