TV MODEL :SANSUI HARD ROCK 21'' PROBLEM : TIME TO TIME ONE HORIZONTAL LINE COMING WITH BLACK SCREEN


Hi The problem of your teevision is what we called the vertical line problem.The problem is in the vertical section of the board.There are many of cause of that problem.First is either loose connection,the circuit at the vertical section have cold solder so its need to resolder using soldering iron.Second,it maybe no vertical supply,its better to check the 12 volts dc supply of vertical ic output.if thers no supply in the ic,there a open resistor near the flyback.try to replace.Third if theres no loose connection and have a voltage supply the problem is either leaked capacitor or deffective vertical ic output. Commonly in that problem is the loose connection,try to resolder the verical section.

My Sansui SY-21-Eye TV is not showing picture is not horizontal. It is tilted with a little black line on top. I mean the whole picture is little tilted with a black line on top and on bottom some part...


I too had the same problem but i have solved it. When i was scrolling all the channels, a hidden menu appeared. In that hidden menu all the tv functions are present. By changing the values we can adjust the resolution.

I have about an inch to inch and half of light colored and looks to be horizontal line at the top of the screen on every channel. Haven't tried anything to fix at this point.


Hi there ! If you know technically try this :
1. try to adjust manually the trimmer at the vertical and horizontal section of your tv (located inside)
2, check for possible cold solder and try to fix it by using soldering Iron and soldering pump.
3.there maybe a change value of resistor inside the horizontal Section.
4. An open and leaky capacitor might also be the cause of Horizontal line at the top of your tv screen . thank you.

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.
