Line across middle of screen, rest of screen black

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.

Those lines are typically horizontal and they go all the way across the entire screen. These black lines could also be caused by damage to these ribbon cables.

Generally horizontal lines are caused by the panel failing, you can try a new tcon but I don't think it will help.

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

I'd suggest to bring it to repair shop if you're not technically literate

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

Middle going across the screen from left to right??
This unit is plagued with bad solder connections in the comb filter board and flatpack underneath the comb filter board. These connections can cause any odd number of problems in video display. If it is that it's not expensive - virtually no parts. If it's a single line across the screen could also be the vertical circuit involved.
My suggestion is to have it estimated at a reputable shop and take it to them rather than the more expensive pu/del charges.
If you would like go to http://www.nesda.com/locator/state_search.php and locate a servicer from there. Kinda like going to the AMA to find a doctor...
Hope this helps!

HORIZONTAL FAILURE AND LINE DOWN THE SCREEN. REPLACE T5A1 LOCATED ON PCC-3-PCB. PT#349P145030(FOR CS-35401,CK-35402 ONLY) Hope this helps! Troy

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!
