•When you touch the CRT surface, you might feel a slight charge of static electricity. This is because the CRT contains static electricity; it does not affect the human body.

•The TV may emit a crackling sound due to a sudden change in temperature. There is no problem unless the picture or sound is abnormal.

•When a bright a still image (of a white dress, for example) appears on the screen, the image may be coloured. This problem occurs in all CRTs, and as the bright image disappears, such colouration also disappears.
