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!
Click the Menu button and use the '+' & '-' signs to select restore factory settings. Check if you get the same line in the BIOS screen, if so then you would need a replacement.
Seems that it is an issue with your video card, Please update Driver for Video card and it that does not help, it is the time to replace the Video card.
You can get your driver from support.dell.com and please enter your service tag to download the driver
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!
Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
