Can Flourescent Light sitting on a monitor damage it? 1

[electronicsfreak]

I know how lights like flourescents cause EMI which intereferes with monitors and other things. However what Im wondering is can it actually harm or mess up the monitor? I have a kind of like night light flourescent light that I sit on my monitor beside my cam for light for its white light to make better pic. Well I just had a monitor go out and wondering if maybe that caused it or if it was just because of old age.

I'm guessing that the transformer in the unit could possibly distort or discolour the picture due to magnetic interference but cause the monitor to fail! I doubt it.

Actually, prolonged exposure can permanently damage the monitor. I had a customer who had a fluorescent light above there monitor mounted on their desk and it caused some damage after a couple of months. I didn't fail but the color was screwed up.

Only time I've ever seen it...Maybe coincidence but I doubt it.

Yeah thats actually what happened to my last monitor the color went to flashing pink. I remember studying in college and stuff about emi and the interfearence so thats what made me ask lol. Anyways thanks for the info very much appreciated.

Damage -no. But the magnetic field can be altered by it. This can be fixed:

Most (newer) monitors have a de-gauss function build in. This should be able to fix the discoloring.

If not take it to a TV repair shop -they have a large coil to fix this kind of problems on TV sets and it will work on your monitor too.

A similar problem can be seen if you have speakers (w/o fertit around the magnet) close to the monitor.

We had a problem with 2 monitors where the display had turned pink. They were not near fluorescent lights but were in use 24x7.
The de-gauss button fixed the problem.

Is there a power lead going to it accross the monitor at all? If there is this could be a problem as that happened to me ages ago, ruined a monitor because the power was causing some kind of magnetic field.

Also speaks like said above never place them near the monitor.

Well the only power cord that was going near it was the little flourescent light which i just uplugged yesterday and removed away from this monitor. Both of these monitors are older ones that do not have that button. I collect parts and stuff on things people give away and since these are older ones like i said they do not have that button. I had the flourescent light on them but its moved the only thing now sitting on the monitor is a logitech webcam with a usb cable running down behind the monitor. Ill probally check aroudn tv shops see how much it is to use that circular device to fix the color on them. I might even build one if I can find the schematics on one.

Hi, that "circular device" is called a degaussing coil. Even if the monitor doesn't have a button labelled "degauss", it probably has that function as part of the "on" cycle. If the color is off or distorted, and the problem is residual magnetism caused by some external magnetic field, - you should: 1) remove the source of the field (and it sounds like you've done that); and 2) turn the monitor off and on from its switch. Most crt monitors that I've seen have this function built in, even if there's not a switch for it specifically. If that doesn't fix it, your best bet is to contact a repair shop. good luck,

You don't have to buy (or build a coil). By the way, that's all a deg-guassing coil is: a coil of wire 14" to 16" in diameter, and an on off switch. Just use your soldering gun (I've done it for years). Hold about 2' from screen, hold the switch on, move it to about 6" from screen (in a slow circular motion, in a steady, decreasing circle). Once you get close, reverse your motion until you're back to 2' away. Release switch. Be careful that the hot tip doesn't touch anything! You may have to do this more than once.

Enjoy the pretty colors!

micker377,

Does this explain why you are a two-fingered typist?
Just curious.

[electronicsfreak]

Not for sure if your refering to me about being a 2 fingered typist but I do not type with 2 fingers. I am a bit rusty however I still type around 65wpm
