Re: bush tv has a circle on screen like looking thru a...
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.

Check for any loose soldering points on the video output card [ a circuit baord located at the neck of the pircture tube]. Resolder all the suspected solder points. Green colour out put is absend now with your Tv.
Hi, that sounds likes a degaussing coil problem,or a magnet have come to close of the tv, you will
needs a picture demagnetizer where you gone put it on the picture tube and making circle on the tube and walking back at the same time you still making circle and enlargin the circle at the same time you walk after 10 feet about turn off the demagnetizer,
that should bring at the normal color; if not thats
