    Had the same Samsung TV problem. Gee thanks China for the cheap capacitors in all Samsung products. They took 15 – 20 year capacitors and made them max. 3 year capacitors. First your Samsung TV will start taking up to 30 sec. to turn on, then random channel switching, random on and off operation, then dead. Then you begin pleading with Samsung or anyone to help you fix it. China made millions, Samsung made millions but you will are stuck with their defective products with these defective capacitors. WHAT A RIP!

    My 6 years old Samsung TV having the same problem that everyone has, clicking when powering up. At first, I was able to watch after it power up, after a few days, it eventually died. I open the cover and examine the capacitors as suggested by other forum, I just don’t see any bulging on any capacitor. They are pretty flat on the top. Not sure if my problem related to the capacitors. Any suggestions is appreciated. Model number: LN52A550P3FXZA Manufacture date is 2008.
