How do I fix moving black pixels on my tv?

[Speeder]

When I turn on my tv and use either a gaming console or display a laptop screen on it, there are a lot of black moving pixels on the screen, is it possible to fix this without taking apart my television? (eg changing display settings)

Some info about my TV:
TV Manufacturer: LG
Model: 42PQ60D
Display: Plasma, 1024 x 768
Manufacture Year: 2009

Yes, I know this is a subforum about PC hardware, but I thought this would be the most suitable subforum to post this issue on.

There are probaby bugs inside the screen.

Like real, living, bugs.

Happened to me a few times, with my TV which is standing right next to a window which is usually open. Little bugs somehow managed to get inside the screen.

They will leave on their own again, unless they decide to die there.

I'm not sure if bugs will be inside the screen, as the only issue on the screen is moving black pixels, which i don't think bugs would cause.

Seen it many times before, moving spots/pixels are always bugs.

bugs, spiders, ants, ect..
only fix is to take it apart and clean it

I should have explained it better, but the pixels aren't really moving around, they are flickering around the tv.

I don't think that will be bugs, so maybe it might be something to do with the settings of the tv.

unless its a plasma or crt, its bugs

led/cfl have a gap between the backlight and lcd panel, bugs can get in there and will cause dark areas that move (rainbow edges due to r/g/b pixels being partially blocked)

Either it’s a bad connection to the TV, it cannot handle the timing, or its dying. Call a repair man because it’s probably just it’s circuit board needing replaced.

Before you do that, reseat all the connections to and from the devices and TV. Make sure your advanced settings aren’t out of wack, use compressed air to dust off the connectors and component ports on your TV.

it either works or does not work, it does not partially go bad
only plasmas do that

bad power board in the tv may cause interference, but that would be more static around the entire screen, but more likely to be no backlight or no power
bad brain board would cause bigger problems
bad tcon would cause backlight with no image
bad led would be dim sections or no backlight
bad cfl is dim/orange sections or no backlight

There is a dead moth stuck inside my LED TV casting a shadow on the screen.

Plasma tv has a sort of pixel static since the pixels are controlled by turning them on and off rapidly. Just how it is, you shouldn't be able to see it from a distance though.
*no wait its 720p, quite low res for its size, maybe a little more noticable on artificial still images as you can find in video games, but on natural images its not so obvious, and looks more natural than lcd.

2009 seems kinda late for a 720p plasma
but here it is

could be a bad power board or mosfets on its buffer board

People forget what plasma's were like already, as I said, this is normal. The pixels are controlled by high frequency pwm/frc/dithering to produce different colors/brightnesses. Even 1080p, they didn't make good computer monitors for that reason, never mind the burn in. The problem isn't apparent on natural images, and of course to this day the uniformity and viewing angles of plasma are still superior.

just wondering, would using a better multiplug hub fix it?
