For Samsung and more television that have too tight tolerance and have problems by the used electrolytic-capacitors , on the powerboard, backlight inverter board and some more the most elco capacitors are between the 10 and 16 Volt Korean ones that will have in priority the problems, replace them by 25 Volt or 35 models with the same size and format in capacity, the capacitors are not self healing anymore after 4 or 6 years , replace always with more voltage tolerance. There is te problem in most cases and sometimes tyhe endcaps of the green colored 3W resistors and (fuse resistors) that can become damaged , but in priority a capacitor problem .
