yung hinang sa loob ng tuner ha, see picture sa taas; hinidi yung paa ng tuner.

yung pinalitan mo crystal eh yung color crystal usually  3.5 Mhz? or some higher siya but since process din siya ng IC (chroma) yung ibang value ang gamit and magdedepende din naman sa filter (capacitor and inductors mo) hence kaya ko pinapa-check yung components mo da tuner section. subukan mo rin palitan yung isang crystal or resolder muna. tapos, you might consider checking chroma IC or UOC kung ito ginamit. hth(hope that helps)!

hindi talaga pede pag 4.5 Mhz  - 6.5 Mhz for FM sound modulation iyan. same lang kung 4.43 MHz e dapat same lang nito. Teka sis, di ba sa A/V mode same lang ang problem? Kung oo, sagot mo dito. It's time na check mo na saan galing Chroma, Chroma IC ba or UOC? bakit andito na hinahanap mo or katabi lang ng 3.5 MHz na crystal ang defective part.

off-topic: censya di ko makita yung schematic mo anlabo. and wala ako schema nito.

ok sa A/V mode, then nasa tuner section lang ang salarin. kunti lang naman parts dito, unahin mo na ecaps then coil sabi mo kasi good ang tuner mismo. then zener diode. then resistors.

update ko lang...
pinihit ko IF niya at auto search, yung dating magandang channel na pag linipat at ibabalik ay nagflaflash ngayun di na nagflaflash ang kulay....yung mga nagflaflash nalang is yung malabo ang stasyon...

na try ko naring palitan e-cap sa palibot ng tuner sis, zener at resistor di pa, may epekto din ba mga smd cap dito pag defective? TIA

oo naman. pag sure ka na defective, observe mo rin baka naman may same label sa di smd type.

nasubukan  mo na ba palitan ang memory? (don't ask me wala ako nyan memory kahit schema wala) ask mo mga masters. may memory ba ito parang pihitin system ito, di ako sure? nakita ko na ito, di nga lang dumaan sa aking mga kamay.  ;D ;D

AGC ref kaya pin, good kaya mga nakasakay dito sa linya? may 2.2 uf / 50 V andf 100 uf / 16 V ba na ecaps? yung sa IF ba ok kaya ang transistor mo err i mean good working condition?

yung sa diode kala ko ba di zener? eh bakit zener diode pinalit mo?

update ko lang po

@mcleod sis napalitan ko na mga ecap ganun parin....

yung diode na open eto body number niya sv0330 ano pede replacement?(sa AGC)

pinalitan ko ng zener diode medyo ok na yung picture, yung nagflaflash na color yung mga mahinang reception nalang, yung dating malinaw na channel pag linipat at binalik di na nag flaflash...siguro konting tuning nalang, pihitpihit....pero yung value po ng diode sigurado may kinalaman yun open kasi siya e........

thanks...
