My TV is a 32" LG about 5 years old. When first turned on it is fine, then after an hour or so, a slight intermittent crackle starts, which then gets worse and worse in the next hour or so, till it becomes constant. It does not come through the speakers and is not affected by volume adjustments. It is definitely in the TV cabinet and is not related to the skybox, that it is attached to.
It would be good to know how to fix this, if it is possible. I have already tried turning off at the plug and pressing the on/off switch to return to factory settings.
Thanks for your interest.
