Hi all, I have a Mitsu TV set ( CT-21M1FM ) that have lost it's luminance signal (gradually, so that's probably a drying electrolytic cap or something like that).
Unfortunately, I don't have the schematics and can't locate the datasheet of the main board last video circuit (Toshiba TA7676 RGB-PAL-SECAM video switch...) that drive the video amplifiers. Thus I can't trace back where the luminance signal stops.
Anyone having either this schematics, or of one TV set using this TA7676, or maybe the TA7676 datasheet.
Oh, the TV set doesn't have PiP.
Any information welcomed.
