Thanks for your response master!!! Na try ko na yong A/V inputs-pumapasok siya sa jungle pero walang lumalabas. para bang dead yong IC. All voltages are normal, halos lahat na ng components natest ko na. Flyback is ok. System cont is ok din. can't be sure sa tuner at crt. audio amp is ok. all crystals ok. One thing is lumalabas yong arc sa anode pero maliit lang, nilinis ko na yung area. TB1238BN is new.

need more info...

nalilito aku ng kunti....
bat nyu nasasabi na reddish ang kulay eh wla nmn pala kaung video display only a OSD nag-aapear... yun ang pagkakaintindi ko sa statement mu...

o bka nmn ito ang gusto mung ipahiwatig.. ruster lamang ang display.. di gumagana ang tuner module dahil wlang station na masagap at reddish lng ang kulay nya..



try mu muna hugutin ang tuner module tapoz set mu sa AV mode.. din observe kng meron ba kaung Video display

yan nlng muna... & den update mu ko

ano nga pala ang chassis nyan ? sc-023a o mc-83c ?
