Hi - when we switched on the tv last night - all the colours were wrong - blue became green. purple faces, a green haze to the screen and the appearance of a circle in the middl eof teh screen.
We can not understand it as the tv has ben working fine for 4 years - and has not been knocked in any way - please can you advise what caused this?
Degaussing is a temporary fix....Follow degaussing coil around
CRT to plug- in lead next to thermistor-----flip PCB and solder
three contacts---Test. If purity does not correct,replace degauss
thermistor--typical board location THP501? part # being
researched.....T.
Your CRT (Picture Tube) screen mask has become magnetized. You need to degauss the CRT. Have you moved you TV lately or at any point had speaker sitting next to it? These are two things that can magnetize the screen mask. Well in any event you will need what is called a degaussing coil to demagnetize the CRT.
Here is the degaussing procedure:
Standing about 10 feet from the TV Screen turn on the degaussing coil which is in a vertical position and rotate it in a circular motion walking towards the TV .
Once about .5 to 1 inch from the TV continue to rotate the degaussing coil and the move away from the TV while still rotating the coil.
Once at the point where you began, position the coil to a horizontal plane and quickly move the coil back about two feet and the turn the coil off.
This will deguass the CRT.
Thank you,
