Query: Beautiful TV with Quality Issues

Like nearly all Samsung TVs, this TV looks good both on and off. Picture looked much better than comparably priced TVs on display at a large electronics store. Bought in December 2008, and TV worked well initially. After 5 months, the main board failed (TV display would not come on and several inputs simultaneously stopped working). After the warranty repair, TV worked well for 8 more months. Shortly after the warranty expired, the display would flicker several times within 10 seconds of being turned on, then remain off. Sound would continue to work, but no picture. Display occasionally would remain on, but required many attempts.
