OSD problem


Should be as simple as holding the Menu button for several seconds. Give it a try. You should get the message OSD unlocked and then the menu button will function as expected.

Problem with Control Panel


It sounds like theres a front panel button that has become intermittant and making contact all by itself. Sometimes when you clean the screen, the cleaner will drip down between the crt face aqnd the cabinet and make the switch in front go bad. Im not sure if this is the case in your problem but its a start. If you didnt spill anything or drip anything into the front panel then your maicroprocessor could be causeing the problem, or the 5 volts that feed the micro could be noisy ie, bad filter capacitor in the power supply. Now as im sure your aware of the hi voltage inside these sets? Its best if you dont have the training to get a pro to assist you as this hi voltage can hang around inside the set even if its unplugged. Good Luck
