    I face colour setting can't control

  • sirahari Jan 14, 2008

    All of a sudden, my monitor (Samsung-Samtron 56V) features--brightness, contrast, etc.,-- are appearing on the screen by themselves. They keep flickering on and off, lock and unlock ControlLock and do not go away even with repeated pressing of the exit button on the monitor. Keeping the exit button depressed even changes the display width, and contrast.
    So I have reinstalled the Operating system (XP). But to no avail. I had a host of viruses before reinstalling the OS. The viruses are gone. Now I have AVG free anti virus running. I have also tried downloading 3-4 antivirus' from the web and run them one after the other. But this monitor problem persists.
    Need urgent help.

    When I switch on the computer The message "Controls locked" appears. I try to remove it by pressing 'menu' and 'exit' button many times. After 15-20 attmpts the message disappears. But screen width reduces. Then I have to re-adjust the screen. This happens every time in the beginning.

Have you tried holding the "MENU" button on the front panel of the unit?

For my 150MP, it must be held in for 5 seconds. (the menu actually goes away. Then you press MENU again and it comes back unlocked.)

Hold the menu button down for 15 seconds. This worked for the Dell E173 monitor I was testing. This has worked for other models of monitors as well. I found this on the Dell support site: https://support.dell.com/support/edocs/monitors/E173FP/En/controls.htm

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
