There is a white horizotal line across the screen of sansui standard TV with a picture showing within this line. The sound is OK. What causes the problem?


Your fault it known as "frame collapse" because the pictures frame has collapsed. It may be caused by a bad solder joint or a failed component. Not a problem for a TV engineer.

SAmsung has two white lines across screen with no picture


If the 2 white lines are in the centre of the screen it sounds like you have a fault called 'field collapse' . The 'x' or horizontal circuit on the tv deflects the beam across the screen which in your case is ok because the line runs across the screen ok. The 'y' or field circuit on the tv deflects the beam down the screen. Without a circuit diagram for your tv i cannot point to individual components.

Horizontal white lines across top of TV screen


Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

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.

This is a vertical-deflection problem. Try to adjust the vertical (height and linearity and hold) controls, which should be screwdriver potentiometer controls on the back of the set.

If this does not work, a defective component in the vertical-deflection circuit will need to be repaired.

I hope this helped you. :)

Hi.

Just read your list of problems The first fault (Diagonal lines & picture collapse from left & right) Sounded like either A poor connection or dry solder joint either on scan coils or scan coil plug / socket on main pcb.
If this were the case the engineer that called out should have spotted this & sorted it very easily. But you say it is still the same so what did he do ?
Did he give you a reciept with break down of what he did ? If yes please post it here for me to go over.

The sound problem you describe has thrown me a little so could you please post your tv model number on this page so I can see if this is a stock fault.

The static shocks you are getting is relatively normal & not a problem unless you are getting them off of speaker grilles or even tv casing if it is silver in colour.
I am UK based & have access to samsung technical but I will need your tv model number.

No colour on television


Hi, It is possible that the reason for the black & white as well as lines across the screen is weak, defective or wrong oriented antenna. If you are hooked up to cable, then it should not be a problem as you can call for service; if on the other hand you are using aerial antenna, you can try to: reorient or adjust the direction to where the antenna is pointed until the reception improves, check the lead in wire (cable or flat) for any breaks or shorts or loose connection, check/clean the connection of the antenna elements to the cable/flat wire, replace your aerial/cable as may be deemed fit and needed. A couple of questions pls if the above does not solve your problem: when receiving from aerial, is the picture full vertically? are you also having problem with sound? If yes, where was the TV bought and where is it being used now? If no, is the image snowy and some channels/stations are better than the others? Good luck and pls post back how things turn up or further information. kind regards.
