Hi All.

I Have a Portable Casio TV21, but It has some issues with the automatic tunning and vertical frequency lock. It has a lot of presets but without any info. I tried to slighty move them but without success and prefer not to embarrass the situation.

I Couldnt found any schematic or information about Sanyo LA5653 and OKI5506 ICs.

I´ll appreciate your help.
