Problems with a KDS Monitor 19 ´´ - Constant degaussing need

[Felipe Ledesma]

I have an AVITRON AV-195T KDS MONITOR.

I have to degauss it continuosly (10 to 15 minutes interval) because
otherwise it gets a little weird (not too much). The side borders get
very curved and the image starts to shake a little bit. I don´t know
how to repair this permanently and it looks the only way to relief
this a little bit is by ussing the degauss feature.

It seems it gets magnetized or something...

Anyone can help?

Any help will be greatly appreciated...

Do you have speakers within one meter distance in any direction from the
monitor? I got a set of speakers once that were disturbing my monitor from
about one meter distance... it was not quite the same as yours, mine was
getting some green spots after a couple of days...

Degaussing is meant to remove alien magnetization of the screen
mask to get picture colours undisturbed by external influence. If the
monitor isn't moved around nor are varying magnetic fields present,
degaussing shouldn't be necessary at all - some people even forget
that there is such a function built in .

As the degaussing circuitry sits directly behind the mains entrance
into the monitor, you may cause a short dip in the supply voltage by
activating the degaussing, which then *seems* to influence an other
fault or weak point of your monitor.

"Very curved and shaky" could mean insufficient syncronization,
instable supply voltage caused by a crumbling solder joint, or
any other insufficient condition caused by aging components.

The shaking suggests to me that there's a nearby magnetic field, maybe
from an electric motor.

What happens with the degauss coil disconnected?
