I have a 99' Sharp 25" tv model # 25L-S100B. I've tried for many weeks trying to find its menu option, but I have not prevailed. I think I'm starting to lose hair from this. The tv has a power button, 2 volume buttons, and 2 channel buttons. No menu button. I've heard you have to press the 2 channel buttons together to get the menu, but i've tried it in every fashion possible. I have an RCA SystemLink 3 remote, but the menu button on the remote definitely does not work. I REALLY need to summon the menu, my tv's contrast is insanely unacceptable!!! Does ANYONE have any remedy to my ailment?
