I started with samsungs in the mid 2000's when lcd tv's are freaking expensive. Lg wasn't really on the market yet, parang its down to samsung, sony and toshiba. I remember sony selling double the price of samsung. This is the reason i chose samsung. To me its not fair labeling a brand na puro lemon or whatever. If there is a negative in samsung its the sound, parang mas mahina. But i think they already fixed that. As for other products like aircon, washing machine, after service etc. i can't comment because i don't have any first hand experience. It's normal to have a lemon or something that will conk out faster than others. It happens to other brands too. Yun sa bleeding sakit ng lcd and led yan. I just make sure my tvs are plugged to an avr then to a surge protector.
I have 3 samsungs, one 32 inch, my first lcd, since 2006, still rocking in my daughter's room. Remote lang not working well na so recently got a replacement.
Regarding dead pixels and bleeding, im sure baka meron din sa akin but i dont even mind them. Imo, Don't even bother looking for these, unless it's something drastic, because you might end up changing your tv very often. Kung drastic ibang usapan yan. Dapat talaga laban mo. Pero So far enjoying naman everything that i am viewing with my samsungs. Knocking on wood.
