Check the check again while thinking, surely 8 and 5 v problem. Found the voltage which should be 8 only 6v left and drop. While before passing r38 ohms and the 10v diode is safe. Try replacing the diode, re-measure the voltage after the diode is safe at 8v. Try turning on and successfully the screen returns to normal. Early damage came
Sometimes when the TV is turned on it can be normal for a few minutes, then the blank screen blinks and blinks.
