SAMSUNG is known by the really famous CAPACITOR problems with Taiwan Capacitors that this condensers are not so good self-healing anymore in about a year of 3 or 4 and have leakage or are deformed. this can be several parts inside the chassis, when its get not the right capacity anymore but if its temperature goes up by time then there is coming up a forming of the capacity slowly back. 20 minutes aware this is the first part where you begin is the mains board of the hdtv
The use of Taiwan capacitors everywhere and too little stress tolerance 16 v where 13 v is used but its all
taken too tight , thats Samsung and many other Brands with Taiwanese capacitors token to tight about the volts .16v 10 v replace with 10 v higher models over the time the size of the capacitors are smaller than before.
replace with good German capacitors or a good Brand Japanese also in the mainsboard in the first place , and replace if there are all green colored 3 watt type resistors if they are used in the mains ACbord primary because the end-caps of this resistors if thats 3 watt type can have also sometimes problems because of shrink and distention because the heat and cold are playing parts by the Samsung resistors they are sometimes terrible of the green 3 watt type. use normal cheap Vishay resistors instead the have also no such problems for shure.
