I have come to this group since it seems to contain the most posts on
this topic. Nonetheless, despite searching, I have not quite found
the answer to my question.
I have an 11 year old Sony TV. For most of its life it has had a pair
of HiFi speakers two feet to either side. These used to be Mission
707s but a couple of years ago they were replaced with bigger ones:
Tanoy R7s.
A few years ago (still the old speakers), the TV suffered some severe
discolouration. This was similar to the effect described by others in
this group: big green and purple patches. I guessed that it was
related to the speaker magnets so I moved them away and waited. This
did not seem to help and I considered bringing it into a shop to be
checked. Luckily, I could not do this for several days and during
these days the set corrected itself. The speakers had to go back to
their original place but the problem did not immediately reoccur.
In fact it was a long time (maybe more than a year) before the problem
reoccurred but eventually it did. Now the problem is occurring more
often (every few weeks) but also clears more quickly (hours).
Previous threads on this subject say that the internal degaussing does
not occur if the power is cycled with the remote control and suggest
disconnecting the mains. How about using the power button on the set,
is that enough? I don't normally disconnect the mains since unless I
crawl behind the furniture to the multiway extension cable, I have to
disconnect the extension cable and lose power to the video as well.
Losing video power is annoying since it is too old to set its own
clock. But if disconnecting from the mains were more effective than
using the power button on the set, I would rearrange the cabling to
make it easier.
Now the question. Is this a sign that my TV is aging and will die
soon? Or are the speakers to blame? Except in unusual circumstances,
they do not move. The TV malfunctions are not linked to any equipment
movements, they appear random but are becoming more frequent.
I am considering replacing the TV but if the speakers are to blame
then I may be in danger of ruining it as well. Are modern sets more
resistant to magnetic fields? Are some models better than others? I
cannot significantly rearrange the furniture so the TV will have to
live with these speakers 2 feet away.
