The colour has gone all funny, like a magnet has been on it but it hasnt because i just turned it on and it made a noise , moments later it changed colour. i used an electric egg beater but it only moved some colour and i dont have a drill or a soldering gun, plzzzzzzzzz help me

Re: my tv don't work
Inside the set is a part, usually a thermistor that kicks in the degaussing coil. That is the part that will clear up any stray magnetic field interference. These parts can fail over time. It sound to me like the thermistor has failed and the degaussing process no longer occurs. This is a $10 part and is usually stocked by any TV service shop. Call around and explain that you need this part replaced to get the least expensive service for this set.

On a CRT this means that the tube has been magnetized - usually by speakers placed too close. First of all just remove all magnets (or transformers) from its vecinity. Next use the demagnetizer that every single tube in the world has: shut down the tv for 10 minutes, start it for 10 minutes - this forces the demagnetizer thru a cycle. Repeat as many times (usually less than 4) as necessary.
ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben
TV's will show funny colors because of magnetic fields affecting the face of the picture tube. A "degaussing" circuit (a coil of wire around the tube and some kind of control circuit) is supposed to try to neutralize this when you turn the set on. Sounds like it's not working correctly in your TV, or may not be strong enough to counter the field.
A real cheap set may have no degaussing at all, or may have a manual degauss button on the back. Does the owner's manual tell you anything? The connector from the coil to the circuit board may be loose. Try reseating it. (Be careful if you take the back off your TV. Make sure it's unplugged, and be aware some parts - especially the picture tube - can store a charge for a while after the set's off and can give you a nasty jolt.) It's also possible the tube is defective, but unlikely unless the set was dropped or exposed to a large magnetic field (like kids playing with a magnet near the face, or turning off a vacuum cleaner right in front of the set).
Hand-held external degaussing coils are available (check eBay). But without seeing exactly how bad the color is under what conditions it's tough to say what's best to try.
Your degaussing circuit is not fully 'demagnetizing' the picture tube.
You can manually degauss it using a strong magnet, but it's tricky.
With a tool made for demagnetizing you simply hold it close to the
center of the picture tube and using a circular motion slowly spiral
outward to the outer edge of the tube, pulling the magent further away
from the tube at the same time. The same can be done using a strong
magnet although the results may not be perfect. You can experiment with
a magnet using wiping motions as you bring the magnet closer to and
further away from the tube.
actually your tv set was placed near object produced magnet especially speakers, used magnet, small one to de-gauss or just like cleaning the the tv screen untill impurity colors gone. need my help....firstname.lastname@example.org
your problem is simple
it is called colour patch.
it is basically due to change in direction or you must have shifted or tilted.
it might be due to magnetic effect like spkr,telephone near by it.just remove from that location.
put of the set for 15 minutes &put it on .problem will get clear.
ask tv tech. to degauss it by dega.coil.it hardly 1 second job.
If you leave your tv in standby try switching it off properly at tv switch leave a few hrs then switch on.
Have you got hifi speakers or anything that is magnetic near tv if yes move it away from set switch set off wait a few hrs then switch on.
Or if the above has not sorted problem the set has a fault with the degause circuit. Its not to bad to repair but you will need to use soldering iron.
Do you have any large stereo speakers near your tv? They have large magnet in them.
It sounds like your screen is magnetized
Your set has an automatic de-magnetizing circuit built into it. This circuit could have failed.
If you have large speakers near your tv, they need to be moved,but you did say that you're sure that no magnetic field was near your set.
