Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...

The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

A thin white line horizontally in middle of screen At first could wiggle the cable conection on back of tv and it would go back to full screen now it won't

it sounds like you have horizontal colapse a very complect repair try hitting the tv if the screen comes up full picture then its a dry joint if not there is an ic or power fault toss it

No picture no sound

Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

RCA F32650 32" White lines with hazy white flickering

Absolutely right about the transistor and also check any adjacent resistors to the transformer and to the line output transistor. Good luck.

Intense white & coloured horizontal line on black background on startup

I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

Tv not working

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!
