Compaq Presario OSD lock-on won't cancel

  TopCat® 22:39 05 Aug 2008

The above computer has the message window "OSD Lock-on" constantly coming on at the centre of the screen, followed by a rapid animated Menu box that auto runs itself through the options. It then suddenly disappears for a couple of seconds before reappearing. The OS installed is XP.

I've checked for sticking buttons on the flat panel monitor and all three seem OK. Looking in Device Manager/Hardware I see it has a Radeon card which is listed twice. Checking further it shows two identical monitors listed as well. I've tried uninstalling one then both of the monitors but they reappear when the computer is rebooted.

Any suggestions on how to fix this problem will be gratefully received. TC.

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

* If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
* If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.

The double installation re. Radeon cards is normal as they cater for two displays.

This is a neighbour's machine sited in a bedroom and a dirtier one I've never set eyes on. The whole thing is real grotty with its case air vents nigh on blocked over and a veritable 'lawn' of yuck growing up between the keyboard keys. Talk about trying to be helpful!

Anyway, I think there is more to this screen problem than what it appears. I'm guessing it could be an internal fault behind the menu button on the monitor. Maybe, for example, there's a membrane microswitch fault behind that menu button. Unless someone knows different of course.

I think I'll tactfully suggest a good PC and monitor cleanup first before proceeding any further. That at least should cure any overheating problems it may have. Anyone agree with this idea? TC.

as I am concerned. The guy has decided to dump this old computer and get a new one. Everything cured at a stroke! I only hope he takes on board the need for an appropriate de-dust and clean up from time to time.

Thanks anyway for your help, guys. TC.
