Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience.

Same answer. Same question

Hello. Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). It looks like your next step is to replace your TV.

Vertical lines are usually indicative of TV failure while horizontal lines are generally an input failure. Try switching to a different input, use a different cable (HDMI vs. component), or try inputting through DVI or VGA. Easiest solution is to replace the current cable you're using.

If there is no picture and 3 vertical lines in the center of the screen, stop. Turn off TV. You have no horizontal deflection happening. Lines will burn into crts and be permanently visible after repair.

No horizontal deflection is caused by Horizontal sweep circuit failure, maybe flyback transformer and associated components. More than a simple do-it-yourself repair.

Bad capacitors. On my set HDMI looks clear, but component inputs have moving horizontal lines. There's a guy named Tbully on AVS forum that did a PowerPoint presentation that will point you to the capacitors to change. Sorry I don't have a link at this time.

this could be a format issue. When you change the channel do the lines go away ? If so try to go into the cable box (assuming you have a cable box) and reset your formats and exclude the format causing the lines.Make sure if your using component cables all colors match up.If this does not fix it replace your component cables/hdmi.All else fails unplug your TV wait 5 min. and plug it back in. Hope this works for you.
