The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.
The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).
The repair will cost around $150 plus or minus.
FEW TROUBLESHOOTING STEPS YOU CAN TRY:
ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.
TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.
If the above steps don't solve ur problem then I suggest you to go for a repair if you don't have any knowledge of repairing it.

I had the same problem with my Samsung LN26A450 LCD TV. I found the following YouTube video http://www.youtube.com/watch?v=Mm51C_RDIZE titled "Samsung TV Repair - Part 1 of 2) (also watch Part 2 of 2) which shows how to easily fix the problem. The problem is bad capacitors on the power supply board. My TV had seven (7) bad capacitors - all 7 had dark stains on the ends from leaking electrolytic fluid and one (10V 2200MFD) was blown with bulging ends. I ordered 7 new high-temp (105 degrees C) aluminum radial capacitors from DigiKey.com matching the Temperature, Capacitances and Voltage Ratings for each damaged capacitor that I removed. I followed the instructions in the video except I used desoldering braid ($3.99 at RadioShack) to remove the solder attaching the bad capacitor leads to the power supply board. Once you wick up the old solder from all sides of each lead wire using the desoldering braid, the bad capacitors are easily removed. Total cost of repair including soldering equipment was less than $50. Thanks to “The Professor” for posting the video and saving me $400.
