Degaussing TV screen

I am in the UK. Recently I moved my 19 inch Sony TV to another room. When I switched it on in its new location the TV had a colour fringe about two inches wide on the right hand side from the top to almost the bottom.



I thought it would go away after switching the TV on & off a few times but it is still there after trying this over a period of about 30 minutes.



I am no electronics expert but I think I need to degauss the screen.



All I have got is an old fashioned tape head demagnetiser (for 1/4 inch tape players). Can I use that to reduce the colour fringing? (I would not go too close because presumably the tape head demagnetiser has a very concentrated area of operation.



Would I use it when the TV is on or off?

Have you tried the TV in yet another location to see if the problem disappears? It's a stretch, but if you are in a steel-framed building that was ever hit by lightning, the girders may by magnetized. It'll take quite a degaussing coil to take care of that. :-)

Hi...

A tape head degausser is much much too small. Not even worth trying, if anything it will make it worse.

What concerns me is your mention of 30 minutes. The set's internal degaussing requires a complete cool down period before it will work again.

Turn it off for a couple of hours; then on for a minute or two; then another rest for a couple of hours. Repeat several times.

Take care.
