Power Up Problem


You have a 8.6v supply error according to the 7 error code being displayed, what you can try is when the set goes to blinking disconnect the Y sustain board (if looking at the tv from the back the board on the left) from the upper left side of the power supply, if the error code stops then you know your Y sustain board is pulling down your power supply and causing the error, if the error code continues you have a probelm with your Logic Board (located under your Small Signal Board) disconnect this from the Y sustain board and see if the error code stops if it does you know that the Logic board is bad, if the error code is still blinking then the 8.6v supply line from the Power supply is faulty and the Power Supply needs to be replaced
