    I have white horizontal lines on the top 5 inches of my screen. 

  • Anonymous May 03, 2008

    We have a Toshiba 27AF43 since a couple of years. A few weeks ago horizontal lines at the upper part of the screen have appeared. I found that this happens when the image size is 4:3. If I compress it to 16:9, the lines disappear, but we're losing quality and we don't have full screen. a catch 22 situation

We have a 27" MTS Stereo color TV. There are white horizontal lines at the top of the screen. We do have a DVR with Direct TV. How do we fix?


U can't.Only horizontal lines on the top parts of the tv screen or the lower parts of the picture screen.Or very light horizontal lines mix in with the tv screen pictures.The "CRT" the picture tube is slowly dying of old age.Quicker than they supose to.The late 90" these problems case show up alot more in standard tvs using CRT tube.Because the CRT and analog design about to be faze out of the market place.The glass molding and those radiation matrials,they used to make those "CRT" picture tube materials,not as good as before.

Horizontal white lines 27A43.


You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

White lines across the top of the screen


It sounds as though you can see Transmission lines which are sent out with any broadcast at the top of an image, The TV should normally blank these out, i suggest checking your horizontal and vertical settings

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.

Sounds like retrace lines. Leaky caps or worse can cause this.. Are you getting any vertical foldover at the top of the screen?

Check for leaky capacitors in the vertical section of the TV or cold solder joints.
I would also check in the power supply.
Good Luck.

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
