I bought a Samsung LN26B360 back on November 18, 2009 but yesterday I noticed the audio sounded muffled on the lows but then it started to affects the midrange but today its not as bad but it still is affecting the lows. I am worried that my speakers are going out but I am still within the return period and I still have all of the packaging. My question is should I get an exchange or should I return it and get the Sony Bravia KDL-26L5000 which is on sale at Best Buy for what I paid for the Samsung? I am just worried about the durability of the Samsung if I exchange mine for a new one. Any help will be deeply appreciated.
