Display problem I am having proview 14 inch CRT monitor.From days its brightness decreased.Now it is giving another problem. monotor light shows that signal is getting from cpu.But there will not be any display on the screen.when monotor is shaked for some time then there will be display. Other monitors are working well with the system.could anyone say solution to my problem

It's time to RESPONSIBLY RECYCLE any 17-inch CRT monitor, and buy a LCD monitor;
used LCD monitors can be purchased for under $50.

It would cost you over $50 to take the CRT to a TV/Video repair shop, for trouble-shooting and repair.

Try holding the control button down on your keyboard and while holding it down, use the scroll wheel on your mouse and rotate it slowly one way or the other. This will increase the size of your screen (or decrease it depending on which way you turn the wheel).

Press Fn+F5 to decrease brigtness Fn+F6 to increase brightness

Try this please.

service your monitor your monitors cadr is problem

What has happened is part of your back lighting circuitry has gone out. Yes it is repairable but can cost most of what a replacement monitor will cost these days. Check that out before spending the money. If the problem is only in the back lighting circuit then expect to spend about $100 for a replacement board.

LCD monitors lifespan depends on the quality. Normal use and you should get 2-3 years of reliable service minimum. The display itself is good for about 4000 or so hours of use or more. The problems that show up are always (well 99.99% of the time) are back lighting problems like you have experienced. You should turn it off by the switch when not using it as every hour it runs the screen save is an hour of usable life. Heat is not good for it so if your computer gets the dust cleaned out to keep it cool do the monitor at the same time. Once a year at least more if you smoke use gas heat and have pets.

Tube monitors have a much longer life but you have the size weight and poorer display to go with them. If you have to go back to a tube monitor don't go back to your 14 ask around and you should be able to get a 17 or 19 crt for free. Or expect to pay no more than $10-20 for one.

Hi there if you have plugged into your external vga port all you have to do is press fn + f8 that should now show the image on both laptop and external ie projector

If you are not a technician you can´t solve this problem because are to desasembly your device and check the Q7 and Q8 and C5 that components are on bad conditions and need to be replaced,I told you because i repaired one of these monitors for the same problem

Try replacin a new display card. If it is fine working.ok
If not try fixing for cold solder in the video section.
I suggest video section according your report the light green LED lighted that shows the power section is doing fine.

Sorry Guys, I have the same problem on my monitor. I am going to repair it. Later I will give you info what might it happen.

cheers,

on crt monitor adjust screen referesh mde to 75Hz

or go to windows safe mod e

You can see your monitor ranges ;
right click desktop -> properties -> settings -> monitor
You'll see Screen refresh rate here
under the that there is a box "Hide modes that this monitor cannot display" click that.
Now computer shows your monitor range in list. When you select bigger value different than list , gives error " OUT OF RANGE "
