You need to have the set degaussed. You can purchase a degaussing coil from many electronics parts suppliers, like MCM electronics. If you get one, post and I will try to describe how to use it properly. It's very easy to show someone how to degauss properly but kind of hard to describe.

The colour on my tv screen has gone strange it is now circles of bright colours can this be fixed?


On a CRT this means that the tube has been magnetized - usually by speakers placed too close. First of all just remove all magnets (or transformers) from its vecinity. Next use the demagnetizer that every single tube in the world has: shut down the tv for 10 minutes, start it for 10 minutes - this forces the demagnetizer thru a cycle. Repeat as many times (usually less than 4) as necessary.

Samsung 794mg --- problem in monitor screen --- uneven colour mix


sounds like the monitor experienced being close to a magnetic field.

if the monitor doesn't have a auto degaussing (demagnatise) function on start up, then try using the degaussing function on the monitor (in the menu somewhere).

if no good, then you can try moving/waving a magnet near the affected area. b careful! slowly wave the magnet from a distance 1st, until you have improvements. too close and it will change the colours further!

Monitor colour change


The discoloration problem is due to the near by magnetic field (magnetic interference or due to magnets) appliances like speakers which are very near to monitors ...
so what you have to do is just keep some distance to the monitor from the speakers and other magnetic appliances and then press menu button & just give degauss..

Strange screen colours


Your degaussing circuit is not fully 'demagnetizing' the picture tube.
You can manually degauss it using a strong magnet, but it's tricky.
With a tool made for demagnetizing you simply hold it close to the center of the picture tube and using a circular motion slowly spiral outward to the outer edge of the tube, pulling the magent further away from the tube at the same time. The same can be done using a strong magnet although the results may not be perfect. You can experiment with a magnet using wiping motions as you bring the magnet closer to and further away from the tube.

Colour fade of my 793s


rainbow colour is normally due to magenatic effect on monitor

 

see that any magnetic thing is near monitor

 

 if it is there remove it

 

.after that put off monitor for 15 minutes & then put on.see if any change is there

 

 if there is any change is there wait for 2 or 3 days it will be ok.

 check for video output section & crt electrodes for normal voltage.

 

it that is also ok then crt is getting weak,

 

please be in touch with me unless it is solved.
