I have a 52" big screen tv and my son touched it with magnets. It looks like it is in 3-D with different colors. What can I do to fix it? The tv is only 3 years old.
It will either recover of its own accord or not. If it does not recover then the damage is permanent. In which case you may as well bin the TV and buy a new one as is will be uneconomic to fix.
