• Weird montior/tv issue?
    9 replies, posted
So 2 weeks ago i went upstairs to get something, As i came back down i noticed these Horizontal lines scanning down my monitor. The lines just keep going down the screen, the lines are sorta like "ghostly" looking or "transparent" Now i tried unplugging things and stuff like that, And i also tried a whole new monitor. So then it must be my GPU? Nope. I came back an hour later, Turned on my tv and now my tv on the other side of my room has the same lines, Except that they're moving up the screen. there also a pinkish color. So it has to be my power or something. And i cant figure it out. Also it seems when people in my house use the microwave or any kind of outlet my monitor flickers for a second. What should i do to solve this? I also tried flipping the breakers with no luck.
Wiring in your house may need work depending on how old it is. In my uneducated opinion, it may be a ground issue. Probably be best to hire an electrician to investigate if you have no clue when it comes to wiring. [editline]23rd September 2013[/editline] Sounds like this.

Could be a ground loop. My tvs audio is making a buizzing noise. not sure what to do. Edit: Okay so i found a "ground lifter" on my monitor cable and the lines disappeared. SO it IS a ground loop. But not sure how safe i feel about using it. Fuck this is annoying.
I keep reading that you shouldn't use cheater plugs/ground lifters under almost any circumstance since they only work if the center screw is grounded (and since your not in a two prong household, I doubt it is). Supposedly, using a GFCI outlet with the ground disconnected would be a NEC approved solution, since the GFCI function would serve as a safety for electrocution instead. However, its really only approved in situations where the house has no ground wiring, so it would probably violate your local electrical code, which would probably run you into trouble if the house is being sold and needs to be inspected or something. Unfortunately, I can't find a legal, cheap, and safe solution. Because all the others, you might as well hire an electrician to fix the ground issue since something is definitely up with the ground wiring in your room or possibly the entire house.
Now thats where im confused. Is it the wiring inside the house, Or do i have something plugged in wrong? Cause i can try to unplug a few things to see whats wrong.

Wouldn't hurt.
Right now im using a cheater plug/ground lifter plug on my monitor(Monitor plug>cheaterplug>surge protector). And no more lines. How dangerous are these cheater plugs? It made the lines go away and its nice. But my tv still has lines.

Provided nothing goes wrong on the monitor, it will be fine. However, if you touch anything metal on the monitor and there is a short, there is a risk of electrocution. In theory, they could also travel through the ground on the video cable as well (I won't say that for sure) and reach the case on your PC. At my friend's house, there was a problem with the power supply on his PC, and if you touched anything metal connected to the PC, you would get a nasty tingling sensation. We suspected there was a ground problem on that outlet, as it went away you plugged it into a different outlet. Fortunately, it was low voltage so no harm done, but that's what the ground is supposed to prevent, so if the electricity leaks to the case, it doesn't shock you.
Well thats a big help. Thanks alot, Now i know its a ground loop after searching for the problem for days. The cheater plug will have to do for now.

But this is due to the fact that our power outlets and central junction boxes (light fixtures) aren't grounded. At all. Only on the loft the outlet the boiler uses is grounded, and a outlet on the other side of the loft. Why did they expect people would just put lights, perhaps a old TV set, hairdryers, etc on their bedrooms? Here I have 9 appliances that can use grounding. My PC, 2 lights, home cinema receiver, PS3, Wii, and my ceiling fan which has a steel downrod, motorhousing / flywheel and canopy.
