    hi there, recently i repaired a dead sharp tv by replacing the jungle
    ic x2701cen1 (exact replacement). It seems that everything works fine.
    I fixed the remote control and we began using it (they havent used it
    for a long time). But now the OSD menu lacks the necessary options
    like brightness, contrast and color control. The tv has no front panel
    menu button. Before repairing this tv(the set was still functioning
    well), we had those options but now nothing. Only Parental control,
    picture, setup. My question is, is the newly installed ic lacks those
    features or is there any defective components like capactors caused
    brightness, contrast and color control to not include in the setup
    menu. First time I encountered this problem. Any advice, clear
    explanation of what went wrong. thanks in advance. I doubt when they
    program the ic the manufacturer was unable to include these options.
    just an opinion. not sure... :)

    you'll need to alter something in service mode. probably some string
    of data isn't quite right.
    try searching for the schematic.
