Re: tv discolouration

It sounds like your problem is magnetisation of the crt. Try to switch it on and off for 3 times: on for 1 minute, off for 3minutes, on for 2minutes and off for 5minutes. Then switch on and see if the discolouration dissappeares. IF not, then a technician needs to check the internal degauss circuits.

Sony wega 28 inch colours wrong, circle on screen

It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.

Tv discolouration

Magnetized The set is probably magnetized and needs degaussing (demagnetizing).
All CRT type TV's have an internal demagnetizing circuit that is engaged when the set is first turned on after being off for the day.
If this circuit is working then you sometimes hear a "bonk" sound (about 1/2 a second long when the set is first turned on. If this circuit isn't working the set will become magnetized over time and will have to be degaussed using a degauss coil available at a TV repair shop (cost aprox. $35.00) and you should have the circuit checked at the same time. A set will also become magnetized if a large speaker (magnet) or motor is close to the TV.

Thank you for your reply. I have since had my TV repaired by a local engineer. The TV needed a new part to restore the colour.

Television picture colour

This is because you have something emitting an electric magnetic pulse close to the TV. Like a large unshielded speaker or large Battery. First thing you need to do is move anything near the TV away and see if that correct the issue. Next would be to degauss the TV. Unfortunately the TV probably does not have a built in degausser.

A degausser is an electro magnet in a circle. you plug it in and run it around the surface of the TV.

Bush tv has a circle on screen like looking thru a telescope


Funnily enough I have been given a 21 inch standard Bush set with the same problem!

It's a DEGAUSSING fault. This means the deguss circuit in the TV is not operating as it should - probably a faulty positor. When you switch the TV on (NOT FROM STANDBY) the circuit that removes magnetism from the screen does not work correctly.

Switch it off, unplug the set from the mains for 30 minutes or so and try it again. If there is no change, contact a TV repair centre.

Make sure there are no hifi loudspeakers next to the TV or a radiator as this can have an effect too.

Colour stain


Yes it is A degause fault caused by either something magnetic being close to tv screen EG hifi speakers.
Or faulty degause thermistor, Or degause thermistor is not making good contact with pcb & only requires resoldering to pcb.
Allso try turning tv completely off at the mains switch leave a few hours then switch back on.
If you decide to take to A repair shop this repair is not expensive.
