Ok, I have a rather simple question. My brother has a Hitachi 19" crt. It is rated to run at 1600x1200@75hz. The thing is, the immage isn't stable above 60 hz. When I say "not stable" I don't mean it flickers like it would at 60Hz. The picture actually shakes as if it were being degaussed.
Here's the catch. It's not the monitor it's self. In fact, my monitor is doing this exactly thing right now (just not nearly as bad). I have had others over for lan parties, and there monitors shake at my house as well. But when I take my brother's monitor (or mine for that matter) to someone else house, the problem disapears. This includes the next door neighbors house.. there are no problems with flickering there either.
So that brings it down to one thing. My power. Something is wrong with the wiring in my house. It is my entire house, as this problem occurs no matter where I am. What could it be? What should I do to fix it?
I'm not an EE, and don't know that much about AC power, but I thought that I may have a ground fault somewhere I shouldn't. Or, some other device in my house is causing a back emf large enough to throw off my monitors.
I forgot to mention. I also have a viewsonic and sony monitor that don't have this problem, Im assuming they have better power supplies and are able to deal with a poor source.
Any suggestions? I bet im not the only one who has had this trouble.
Thanks
PS: this was locked in in highly tech, so i moved it here... hope I can get some input
Some things that have already been discussed:
Q: Are you sure your getting 120Vac, and that the house wiring is grounded properly?
A:yes.. 120vac
as to the grounding, im going to have to tear my basement wall apart to make sure the ground is still intack
i just want to be sure that that could be the problem first
Q:I would suggest some form of line conditioner for voltage regulation. Most of the better UPSs have have some form of voltage regulation, or you can buy a unit without the battery backup. I had some problems that I thought stemmed from power problems (the wiring in this house was done no more recently than 1955) so I bought a tripp lite 2400 watt line conditioner, I no longer have the problems.
A:I have a apc ups, and it doesn't solve the problem, i would like to eliminate it, not just filter it out. And, my house is less than 20 years old.
Thanks again
