My Tv!!!

I dunno why, but I wasn't thinking and put my Speaker ontop of my TV while I was cleaning and dusting... I forgot about the damned magnet. Now i have a purple discolor in one area of the TV.

Any one know how to fix it?

BTW It ain't bad, but it is annoying.

    Okeee dokee, here it is, but it takes a lot of time, and its a big bitch of a risk...

    I set my Logitech 680 sub next to my 36" I had just fixed (ooops). I turn the TV on and it was RUINED. I got peeved and started seeing what I could do with the sub, and after about two hours of moving the sub around with the TV on, I just about had the whole thing fixed. I had to get the TV in the air, and hold the sub at different angles, but I finally figured out after some trial and error how to push the picture around to get it looking right!! Currently its got one little corner thats off, and the red is just not right, but you really can't tell.

    My recomendation, don't do what I say and see if there is a better way. It was a bitch, and I can't guarantee it won't make it worse in the end! :)

    Have someone come out and degauss it professionally. That's the safest thing to do.

    Try leaving it off for a day or two and it may fix itself. It wouldn't be the first time.

    Yeah if it doesn't clear up in a few days, you'll need to get it degauss'd.

    If it doesn't clear itself up, get a magnet and sort of draw on the discoloured areas untill they change back to the right colour. Worked for me.... quite fun too....

    Yea that's works too, though I wasn't gonna recommened doing it, because it can have the opposite effect, but yeah, I've done that a few times, and it works a treat. Just use the a magnet to essentially drag the coloured patches off the screen.

    if speakers r magnetic...why are center speakers made to be put on top of the monitor?

    I think most speakers these days are made with magnetic shielding to prevent problems with for example a center speaker. However, subwoofers create a lot of magnetic force so I guess it's harder to shield well. I'm not an expert though.

    Sub woofers use huge magnets and they are not meant to be put next to VDU's so consequently they dont bother shielding them...

    Normally centre channel speakers should not go directly on top of a TV due to the magnetic interference. This will cause the distorition in the picture tube. My centre channel hangs in the cabinet with 6 inches of space.

    In order to get rid of that distortion the tube must be deguass'd. It can be done with a degaussing magnet but if you've never done it before you can end up making other distortions....like leaving an iron on the shirt too long..you'll end up burning the fabric.

    Hope this helps.

    Thsi speaker came out of my truck... I took it out becuase I could not seem to figure outw here the bad wireing was at, the speaker works perfectly, but the god damned wireing is fubar somewhere.

    Well, too LONG a wire can cause signal loss, but if you are getting pops and static it is often one of two things: Wire with insulation off that is grounding on truck (and a small nick with a large amp pushing signal can drain a LOT of signal); or interference from circuits nearby along where the wire is running. IF it is distortion, the channel to speaker might be set too high.

    If nothing at all, chances are the wire simply was severed(cut clear through), and the usual culprit is either no rubber bushing in hole it was pushed through before it was pushed through(friction or pressure against a hole edge WILL do that), or possibly a single subchannel off and not wire at all.

    If static or pops, try this: unplug one channel at a time worth of wire, see if the rest of tspeakers suddenly sound GREAT. If so, then trace wire and find bad place, or pull a new one. If all options for taking one speaker offline leave your speakers and wires alone and put an EMI\EFI\RMI bypass-to-ground filter on your input power line and see if that helps a bunch. You may have to tweak it a LOT, but engine circuitry and primary circuits CAN feed back into truck stereos and quads, and amps just take and amplify the false noise riding the power in sometimes, resulting in epople going nuts for months trying to isolate a power input (from external cirucit feedback) fault that ends up not even being in the sound system.

    AS far as TV, turning off and leaving off a couple days might well work for a newer one, as some new ones autodegauss on poweron. Have seen more that simply have a manual degauss, frequently a symbol hidden on a menu with an inverted U with a slash through it meaning degauss. This is also true of many monitors, gegauss CAN be amanually triggered on OSd menu and the sysmbol is often the same.

    Part of the reason a TV or monitor without a builtin degauss needs to be professionally done is that the gun uses high amperage and high voltage to load a picture. The tube needs to be discharged first to really degauss right, and folks have been badly hurt by electrical charges from a tube not dishcarged right or touching the inner power cirucuitry exactly the WRONG way.

    If you use a magnet, try a light weight one to start for a small color distorion, essentially you mag charged part of a screen and the idea is simply to discharge that part without damping other parts and getting a rainbowish halo effect out of your work. So, use the end NOT used to pick up metal to draw with, and use a bar magnet and not a Nicor or very powerful magnet and patiently redraw over it working from center of disturbance toward nearest screen edge and than work outward parallel to first cleared up thick linish area you make.

    Try ignoring it. The TV will degauss itself every time you turn it on. It should eventually clear up. You can't degauss it with a magmet, you have to use an ac coil with an alternating magnetic field which is drawn away from the screen slowly.

    bothered.

    Yeah, pretty much all TV's today automatically degaus when you turn them on.

    My 19" Sharp TV degaussed when you turned in on, and you could hear it. My 27" JVC doesn't make any noise other than the image on my monitor will get wavy when it turns on.
