Horizontal lines on LG TV

I hate to give you bad news but about 90% of the time horizontal lines come from a bad panel and if that's the case the set isn't worth fixing as a panel costs hundreds of dollars

Horizontal lines on screen HPCQ509

Lines on the screen are usually caused by a hardware malfunction in either the lcd, lcd cable or the GPU.

Do the lines appear immediately after power up the computer? Or only when Windows starts?

Can you hook the laptop up to an external monitor to test?

How long have you owned this laptop?

I have a Mitsubishi CS-3125R that displays a horizontal line with sound. I suspect the horizontal transistor is out and cannot find one. Any ideas?

You are misleading yourself. When you have a horizontal line across the screen it means that the vertical circuit is not working. You see, the vertical circuit moves the beam up and down which is not happening. The horizontal circuit moves the beam left and right and it is working. Your set probably needs a new vertical output IC and some electrolytic capacitors that work with it. The caps dry up with time and harm the output IC.

Black horizontal lines

Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

Horizontal lines are appearing and moving acrosss the screen of my View Sonic E50C Monitor...

What is wrong with your monitor is that the Horizontal section is going faulty, the lines you are seeing are the Horizontal Retrace lines, usually invisable in a working unit. It is often a faulty capacitor(s) OR a Diode breaking down.. in the area of the Flyback Transformer. Probably time for a new one unless ya can fix it yaself.
