Viewmeter on Viewsonic crt monitor

I have 17" viewsonic CRT monitor.When I start to power on, the VIEWMETER on screen is missing.If you boot your CPU, nothing start at all.

But if YOU REST your monitor the whole night, the viewmeter will appear on screen and ready for use.

Its seems there's a problem on component of power supply ckt. Either horizontal, controller or switching.What shpd i Check.

It seems that utilizing the monitor for more than an hours and re-start again, the viewmeter will dis-appear.

    The problem is the monitor itself. I test it w/ other monitor and its ok.The viewmeter screen(self monitor test) is missing or no power to the crt itself.However the power led is at green(ON state).There is no raster on the monitor.

Just check the power cable from the monitor is connected correctly and plug from cpu to monitor is connected properly be sure is there an loose contact... if it doesnt works means then give reset button in monitor... check the power and frequency control properties in bios .... may be properties is user define or is in maximum saving mode just change it to mininmum saving mode will work...

Problem with 17" ViewSonic Monitor

The same problem w/ my viewsonic E70 17" monitor.The viewmeter or viewmatch color on screen do not appear when power ON, although the green led power is ON.

But if you rest your monitor for about 10 hrs or more the viewmeter will appear when you power ON the monitor.

You can now start your CPU.

Remember : No viewmeter screen on monitor when power ON, means no supply coming out the picture tube or high voltage.

But if there is Viewmeter on screen , this normal and OK>
