I have a CRT tv and the picture is just a thin band in the centre of the picture tube. The sound is ok


That is called "Frame Collapse" because the picture "Frame" has collapsed into the single horizontal line.
It may be caused by dry joints or output failure of the frame output stage.
A fairly inexpensive repair.

Horizontal blue line in centre with black back background


This fault sounds like a frame colllapse. The supply voltage to the frame IC may have gone open circuit or the frame IC itself has gone faulty. Unless you are experienced with electronic repairs I strongly suggest you are best to take it to a repair centre.

JVC 27" CRT TV AV-27BP3 display shows single horizontal line


I have a similar problem on my CRT computer monitor (AcerView 76c). It is an old screen and I think it is just at the end of its life, much like your TV. Having some background in physics, I would be pretty sure that the problem is with the cathode ray tube's vertical deflection system. The horizontal deflection electrodes are working while the vertical one is not. This results in a display of a single horizontal line (or in my case, a few superimposed) in the centre of the screen. Where both X and Y (horizontal and vertical) deflectors fail then the electron gun firing would result in a single bright spot in the dead-centre of the screen.

So really, we have no choice but to move on and buy a new set as repair is probably just as, if not more, expensive than replacement with a new device. Seeing as your post was in 2007, I hope you managed to solve the problem.

Best wishes,

a bright thin line in centre is called horizontal line. first of all do not keep tv on unless it is rectified. BUT If you want to put on tv keep brightness minimum to protect your screen for any demage. now solution your problem is in vertical section. 1 check vertical supply. 2 check parts in vertical section or loose contact. 3 yoke connrctor loose 4 ic defective It is not serious problem can be rectified easily
