Re: Is it harmful for TV & monitors if we put a telephone set (contains magnet) over
In one case, I saw it permanently caused damage. The user had put stereo on TV.
If colours are more disturbed, strong megnets and megnetic coil is used externally although internal degaussing coil works satasfactory in most instances. In this case, although colous were fixed after demagnetizing but after few hours it reappeared. After two or three tries, which were not successful, I returned th set. After some four months later, set owner told me that he had shown it to many techs but it is not fixed. A long time exposure to alternaing megnetic field could repair it but that was not practical.
