One of two things, if you have a lot of use on the set or if it's on every day for a long period of time you probably have a worn out picture tube. If this is the case it would far exceed the price of a new set to repair, if a picture tube could even be found for it.
The other thing could be open transistors on the CRT circuit board. Based on it's age, it's probably not worth repairing unless it's a very large set 32" or 36" .

When i turn my tv on the sound is great but the picture is very narrow.My tv is at least 8 yrs old.


something similar to this happened to my old T.V, with mine it started to go wrong colours, the screen started to fade, with it being 8 years old, you may just need a new one, they will eventually fully break, so its best to get a new T.V

I have a bush colour tv and there is a blue,green,red colour wash right across the picture so people''s faces look half blue,green red....sort of as if there is a rainbow across the screen.. i do not have...


It sounds like your TV may need degausing.
Is your TV situated near to any loudspeakers or other devices with large magnets inside them? Or has anyone been near your TV screen with a magnet???
You need to try to get the screen demagnetised (degaussed). Many TV engineers have a degausing coil that could do this. It only takes around 20 seconds at most.
Some TV's like Mitsubishi have a DG button on the remote, that does this function without the need to call out an engineer! It only needs one press of the button every few years!

Red, green and blue colours diveded on my TV


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

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

 would this be the picture tube?

no, not at all.

it might be due to change in direction

 or some body might have turned  tv direction

or any magnetic thing might be near tv.remove it like speaker or headphone etc.

put off tv for 30 minutes & see it will be ok.

hope this will help.

good luck.

Remote not working


Sometimes dust is accumulated in tv remote receiver sensor. This will give you the malfunction. Because your statement says TV is about 8 yrs old. Better solution is make one general service. If you have remote checker check the TV original remote working or not. We say universal remote, sometimes even technical person does not know how to use. Because in each and every brand and model there is a secret code to initiate the version. So better make one general service and check in your original remote it is working.
