@jayeff My samsung tv 2014 model too is not working since i unplugged it for a week. It was rainy aeason here. Now no standby power red light. Kindly advice
@xenab11 What is the model number of the TV? (look on the information label on the back of the TV) Have you checked that the power outlet that the TV is connected to is working OK by plugging in another device e.g. a hair dryer and see if it works OK? If the TV is plugged intro a powerboard (powerstrip) try plugging it directly into the wall outlet and check. If the power from the wall outlet is OK then you would have to disconnect the TV from the power and remove the back cover from the TV and inspect the power board for any obvious damage. There is a fuse and a surge suppressor on the board near to where the power input connects and these would have to be checked by using a DMM’s (digital multimeter) Ohmmeter function. When power is connected to the TV the power board supplies a standby voltage signal to the mainboard and it is the mainboard that turns on the red standby power light
