  1. I have a chassis from a sanyo television (chassis no g5v-2558c1) which
    has has no luminance on the video inputs or the coax/tuner input, it
    does however display internal menu's fine.

    The IC101 is listed as a sanyo LA76170, I've searched all over for
    pinouts of this on the internet but haven't come up with anything. Does
    anyone have a pinout for this chip?

    Also any idea of where I can start to try and fix this problem. Like I
    said there is no luminance on the video inputs but the menus work fine
    so I am pretty sure the lum signal is getting lost somewhere around IC101.

    thanks for any help you can provide :)
