Hi , My monitor (Philips CRT monitor 109B50) keep showing the phrase 'LIGHTFRAME ON LIGHTFRAME OFF' why is it so? Lastly the blue configuration box with language/zoom/adjust ,eveything ... kept appearing and manipulate itself to adjust the settings thanks

Replace the monitor, is dead.

Hello.

Switch the monitors on your video card to see if the monitor or the video card port is the problem. If the same problem occurs on the left side with a different monitor, the video port is problematic. If the problem switches to the right side, the monitor is problematic.

Or, hook one monitor at a time to test on the right and left sides.

Hope this helps.

Can you explain the problem a bit more.

You are locked out of the OSD or the options are not available on the OSD. OSD won't go away?

Sounds like just a system error have it. Can you reset it?

Hi there,

As you say that the monitor was still under warranty. May I know the location were you located and I will try to locate the nearest service center for Philips on your area.

Let me know here again.

Thank you for using fixya.

I am not able to find the solution but I have got the very same problem with my HCL LCD monitor.

that is a system error have it reset

no its not a virus the problem is your monitor itself.try to contact an expert technician of monitor.i think there is a part of your monitor that is already defective.

It has to be either a cable or an IC issue. Get your cable checked first (VGA cable)

your problem is in blue color cathode circuit. as you say that it becomes ok tha5t means 1 cable wire is loose from computer to monitor. 2 crt base loose. 3 loose contact in blue video ckt. 4 signal processor cable to crt board connector loose.(blue wire)
