Colour Hi  Turned tv on and the colour was in circles of each colour like a tie dyed t shirt sound works picture works just weird colour

The CRT shadow-mask may no longer be degaussing, or the shadow-mask in the CRT is defective.

In or near to the power supply there is a thermoresistor that controls the degausser coils. When the set is turned on this thermoresistor gives a momentary high AC current to the degausser coil with a rapid decay for slightly over a period of about 200 ms or 1/5th of a second.

If this thermoresitor is defective, it will have to be changed to resore the degausser coil to work again.

On rare occasions I have had a bad degausser coil that had to be changed. I have also had the shadow-mask in the CRT become defective. The fix for a bad shadow-mask is to change the CRT. This is not feasible for this TV set!

You should get an experienced TV service tech to fix this for you.
