I had a Simsung with capacitor problems too, never Simsung again for me. On purpose they use too weak capacitors. Too bad the TV's started to break during the warranty period many times. I'm affraid it's not just them who on purpose design such flaws to their products.
Samsungs are damned good TVs. Well worth getting fixed properly, as I did with mine after 8 years reliable use. Still going strong now, after another 3. The fix cost £90 in UK.... and that was a home visit.
I have had 3 different companies take 5 attempts to fix my aircond (leaking gas)...still no luck. This and other items that I needed 'repaired' has led me to the conclusion that the skills are not available to fix anything, so better to throw it away and buy new
