My 19" Crt Monitor is blurry on windows 7 64bit


The Crt monitor may not have a higher resolution rate that the new ones have for windows 7 64bit, if that is not the case the monitor has a high voltage problem in the flyback transformer, but! it does have a focus adjust, use this with extreme care, may solve problem.

I just inherited (literally) a virtually new eMachine 786N monitor. I say, "new" because the previous owner probably logged no more that 100-200 hours on the thing. Hooked it uop to my HP...


Sounds like symptoms that the monitor needed to be degaussed (pronounced "Dee' Gowsed"),
and, since most modern (conventional CRT) monitors will degauss themselves upon power-up,
it looks like your restart addressed the problem.

Usually, a CRT that need to be degaussed will develop blurring at the edges first, but its possible
that the monitor was affected by stray magnetic field(s) over time, and failed to successfully
degauss at initial startup (the degaussing circuit won't necessarily succeed the first time if a large magnetic field has built up).

Here's your wikipedia entry on the concept:
http://en.wikipedia.org/wiki/Degaussing

Here's a how-to, in case you want to (or end up needing to) do it manually:

It looks like a .PDF service manual may be available free here:

Everything on the screen is blurry... not unreadable, but almost like there is a shadow behind everything.


[u][b]LCD Monitor Shadow Effect[/b][/u]
This problem is best described as the LCD monitor "Shadow Effect".
The solution to this very simple. No software or hard ware changes required.
The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise.
[u][b]Solution: [/b][/u]Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.
Thats it. Your shadow effect is fixed.
Thank you.

Acer screen is black or blurry


If you've connected an external monitor to your computer and the image is coming up fine then that means your video card on the motherboard is good.

The only other parts it could be is the LCD Flex cable that connects to the LCD screen to the motherboard, the LCD Inverter that powers the LCD screen or the LCD screen itself. Usually you can find a used screen that is complete with all those components on ebay.

Blurry Screen


Delete the plug and play monitor driver and reboot. Trouble is this worked for only one day and had to be done the next. Wish I knew a permanent solution. It appears to be a driver issue. Will see if I can reload the monitor specific drivers instead of plug and play.

Screen goes from blurry to clear to blurry


The first thing to check is for loose conections,the problem is related to the high voltage but it can start in the main board with one component loose,when the high voltage is developed it goes to what is call the distributor block,a lot of sets have the focus and screen controls coming out of this block for each picture tube,this block might be bad but before we go to him we need to check everything is solid in the main board.If you are familiar with electronics you can remove the back cover and tap the chassis with a wooden or rubber handle to see if the set reacts,if it does you need to be atentive what area makes it react and flip the board to do some resoldering,If you are not too familiar with tv service you need the assistance from a servicer.Let Us know how it goes or if you need more information.
