t con board failed if its half and half. can also be a lose cable on the screen to the tcon board from the lcd screen side. Tcon is in the middle off the screen on the back.
likely coming from main board which is involved in all signal---on screen display comes directly from a different area---4 years is about the life span of one of these sets---Google the model number with parts to see which boards it uses and what they sell for.
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!
Less than a year old tv.Ur tv still have the manufacture warrenty.Look in ur owner manual,call the tv manufacture 1-800.... numbers on the owner manual.Talk to their customers service department,what locations or what shops they hire to call,to take care their product that still in warrenty.
I have the exact think happening on my Samsung LN46A530 and it has just been 2 years since I bought it. There better be a cheap fix for this because a $2,000 product has to last a lot longer than 2 years.
While you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image.
Let me know what you see.

My new TV LCD Samsung LC32C530 Series 5 has one half darker and with less contrast than the other.This is noticeable now always. There is a distinct and clear division down exactly half the display which separates the dark and light sides.. Any ideas?Thank you.
