Dear along with greeting you cordially I tell you about the problem that I have been lately, I have a somewhat old Samsung TV whose model is CT14F2S and its board model is K15A, from time to time the TV to present a strange behavior at the time of unplugging from the mains power for a period, this equipment to re-energize did not turn on, the warning light took a while to turn on and even more to turn on all the equipment, this eventually became more acute. At the present time, in case of losing power this equipment takes between one to two hours to just turn on the indicator light and maybe one more hour to turn on the TV completely, at first glance everything is in order, it does not show traces of burned the only strange thing was the main filter capacitor (400V 220uf) that was starting to inflate, I changed it for an identical one, but the problem remains the same, then I reviewed the Samsung service manual for the specific plate model, I've Revised the points mentioned in the Troubleshooting section, punctually 5.1 NO POWER, but from that revision the pieces described seem to be all in order, as well as the values in tensions in the IC801, the values read on the pins being the following: 1: 315V 2: 0V 3: 12V 4: 0V 5: 0V I also tell you that once the TV is turned on it works as normal, it responds to the changes of channels and volume without problem it can be turned off and on without problem (without unplugging). I hope someone can give me some indication of what section to see, I have knowledge of electronics but not specifically about televisions, that's why I appeal to their vast experience in the area. pd: Deputy manual plate K15A SAMSUNG K15A.pdf [1.93MB]
