I left my tv on when I went to bed and the picture was fine. Then I woke up and turned it off. When I came home and turned it back on, the picture was blurry all around the tv except in the middle of the...


is the blurry all around the picture have different color like a smear of red, blue or yellow?
if it is i think the posistor of your tv is not working. it is the one who activate the degaussing coil around the picture tube the prevent color miss-landing upon opening your tv set.

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.

hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners?
If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened. jaredreyesbalderama@yahoo.com GOODLUCK

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


HELLO

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.

ALL THE BEST! (:-)

The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

I believe what you have is a convergence problem and it is usually caused by two Integrated Circuits going bad which also opens up one or two resistors associated with them. Replacing the Convergence Ic'S - (Ik04 & Ik05) and Resistor Rk62 a 1.8 Ohm .5w. Metal Film type should take care of the problem. As far as costs involved, I would guess about $350-$425 to get repaired. With it only being about 4 years old, it should have that many more years left of good use for you.
