pahelp ako mga masters,
may homeservice ako kanina na 21' sony,dinala ko jnalang sa shop ung board and crt circuit.check ko fuse laging pumuputok so pinalitan ko regulator nya strs6707.
nag power on na sya kaso di gumagana, nagbiblink sya ng continous blink, tiningnan ko sa sony code "no reply from jungle ic daw pagganun". niresolder ko jungle pero ganun pa rin,wla na ako oras sa shop kanina kaya umuwi na ako, hingi lang ako ng kunting guide sa inyo, Kung no reply from jungle ibig ba sabihin di gumana ung jungle? meron naman kase supply na pumasok sa kanya pero wala sya horizontal out na about 5 volts(kung tama ako). any idea para sa pagcheck ko bukas? di ba gagana ang sony pagdi nakakabit ang circuit sa deflection and picture tube?

tnx

filter cap ng supply ng jungle pala yun... shorted na yan kaya bagsak ang voltage ng vcc nd jungle ng unit.. saang part naman ang diode na sinasabi mo sis?
