The easiest way to troubleshoot your problem is by connecting your laptop to an external monitor. WHether you have one at home, or need to take it to a friends or your place of work, start by attaching the cable to the monitor and you laptop. Then start your laptop up and hold down the fn key and press the F5 key and let go. This will trnasfer the video signal to the external monitor. If you can see the normal display on the external monitor that you would normally see on your laptop, you problem is only the LCD screen panel on your laptop and it would need to be replaced.

If the same horizontal lines appear on the external monitor, then your video/graphics ship on the motherboard has failed and you'll need to send the laptop in for repair or replacement of the motherboard to fix the problem. I send these advanced problem laptops to any of several repair vendors on eBay and have had excellent results. Simply go to eBay and in the search box type in Laptop Motherboard Repair. You will be sent to a site with many vendors there capable of doing your repair. If the prices seem to high for the relative current value of your laptop, it may be time to consider upgrading to a newer one.

Good Luck

Please connect your laptop to an external monitor. If there is no occurrence of the aforementioned then the problem here is the LCD display. However, if it does appear on the external, definitely its your video graphic card that is integrated with your motherboard. Please let me know if you need further assistance. Thank you and regards.

How do I fix my Sharp tv model LC-42D62U? On the tv screen now shows horizontal lines with repeating ghost images.


Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines


Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse


Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!

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.
