Question about Toshiba 28N33 28" TV

1 Answer

Colour interestingly different!

The colour has been changing for a while now. Sometimes the screen lightened significantly or the colour intensified +the tv seemed to try to fix itself in that it made a cracking sound the picture went then returned with better colour. Now there's a large patch covering most of the screen with a deep pink/purple hue and only a corner or two with green. A friend suggests a thermo something may need replacing or I may need some impliment that is magnetic and sweeps the screen. All out of my area of knowledge. Any ideas please?

Hitachi C21 model.The colours on screen have got scrambled.

It sounds like something has left a strong magnetic field on the face of the picture tube, and that's causing the colour distortion. The electron beams from the tube's colour guns are hitting the wrong spots on the face. There is a degaussing circuit in the TV that tries to neutralise such fields every time the set turns on. Sometimes electrical equipment (particularly motorised appliances like a vacuum sweeper) operating too close to the TV can leave a field too strong for the degaussing circuit to cope with. Or a failed part in the circuit may have made it inoperative.

A hand-held degaussing coil can be used to remove the field. You can purchase one online, or call a TV service technician. It used to be a standard tool to carry.

Another possibility is that the tube has been damaged. There is a very thin metal mesh screen called the shadow mask behind the face of the tube. If this mask has been warped by a strong magnetic field or a mechanical shock (if the set was dropped, for instance), you will see the same colour distortion. In this case, however, there is no repair other than tube replacement. And that is likely to cost more than a new set with parts and labour.

Colour change on tevion tv

is all the screen the same colour or is it patchy. It could be the degausing cerquet (if patchy). Or maybe just to be degaused with a degausing coil.

My Tv has lost it color on all channels, it looks as though the channels are black and white

sometimes t.v's time travel it has clearly become stuck in the 1950's hence has lost its colour. you will find if you climb into the screen you can teleport into the central vortex governing the screens travel and retreve it, unfortunately t.v.'s that time travel rarely recover from time travel due to the acid wave of the 70's and sometimes bring back too much colour due to the LSD exposure.............

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.

No color sometimes

So long as your reception is good, sounds like colour- killer circuitry or something that is killing the colour burst pulse.
Oh well, small TV's are pretty cheap now!
