Screen turns off/screen tuns blue

Good Day, rbls;
This is a generic description of a common concern of this type. 90% of the time if the pic turns a color then turns off it is the picture tube.
If the picture is lost and the pic/screen turns blue it is normally a lost of signal from the TV's source (cable box, vcr,dvd & etc), check all cables, try different inputs & etc.
Good Luck, big IRISH. For more detail e me at mmrkcar@yaoo.com
