A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color. https://itstillworks.com/causes-horizontal-lines-lcd-panel-37988.html

Line, faults & possible causes to both Plasma & LCD screen are given with illustrations. You can get an idea about the fault to an extent.

Really?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

LCD TV Repair No Power Power Supply Common Symptoms Solutions How to...

The problem is the LCD panel went bad, it can't be repaired, you have to replace it.

hi i have a 50" magnavox that has a problem, i was looking at several websites and i find out the dirfferent posibilities.
in your case i have 2 posibble answers.
1) negative image
tv turns on and shots down in 2sec
flashing pixels on screen
dark image
has sound but no video
screen goes black and then return to normal picture
vertical color lines on screen no video
vertical color lines with video
vertical bars on screen
horizontal lines on the image
picture goes red after while
IT COLUD BE (X or Y or Z SUSTAIN BOARDS )

2) just left part of screen working
just right part of the screen is working
vertical and horizontal lines on screen
part of screen not working
some functions not working

The connection to the lower screen is probably a bit broken. If you feel up to it you could take your DS apart using a tri winged screwdriver (can be bought from www.whitedog.co.uk/catalog/nintendo-wing...) and check the connections or you could just send it in for repair.

this symptom is what we called vertical fold-over. vertical fold-over is characterised by a white horizontal bar on the bottom or top of the raster due to the concentration or compression of the trace lines. it an image is present, the bottom or top portion is fold over. this is caused by a vertical deflection current with poor linearity, which compresses the trace lines at the bottom or top of the screen. this symptom is is caused by a defective sawtooth wave genetator circuit, or improper biasing or defective feedback circuit of the vertical drive or vertical output transistor/ic. the negative feedback circuit in vertical deflection circuit compensates for the linearity of the trace portion of the sawtooth wave. a decrease in the capacitance of the sawtooth generator capacitor is usually the trouble. but if you do not understand anything what i have written here, better bring it to a qualified tv technician for your own safety also. good luck!

Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
