The external power supply is the problem. The small box that is connected to the outlet plug has an internal problem. If you can get inside of this box, you will find a capacitor, 16 volts, 1000MF at 105 degrees . Replace with same value and the capacitor next to that one is a 25 volt 1000MF at 105 degrees. Replace as well with same value! Ask a TV tech or a hobbiest to do the work for you. Thanks for asking.!
