When turned on there is a horizontal line across the middle of the TV screen. Please help

I would think that someone, somehow has hit the TV screen with something. My TV screen has a black line going across the middle horizontally and it intersects with a colored line going down the side vertically. Wher the 2 lines intersect is where it was shot with a bb.

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv . 

loose wire check connections

You would need to replace the flyback on this and your looking aroung $65 parts and $85 labor to shore this problem up. We can recommend you a repair shop or you can purchase a new TV its all up to you

It could be a defective Y-Buffer board, or a defective Plasma panel.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Picture is reduced to a straight horizontal line across the center of the screen.

thats the VERTICAL OUTPUT IC that went bad , needs to be replaced . hope this helps

Sounds like the flyback transformer is bad. couple of 100 dollars if it is that

this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
