Friends, I have a LG 60UF855V TV here, I couldn't find any service manual for it. AFTER plugging it into the socket, it reacts to being turned on, so it can be controlled with the remote control, but the screen does not light up, against the light you can see a streak with grain at a certain stage. The source blinks repeatedly 5 times, there is an orange light. What could this mean? I suspect the problem is in the power supply, I only measure 65V as you can see in the picture. It doesn't matter if the LED backlight is connected.
