Good afternoon, I got this tv that does not turn on.When connecting it, the green LED turns on directly and when pressing power on the keyboard the LED turns off, but when turning it off from the remote the LED stays in red.When the LED is green The source delivers 24v and 3.3v that go to the plate that lights the lamps and 12v and 3.3v that goes to the main board. The fault is that the TV does not turn on but in my opinion the source delivers the correct voltages.

Hello, the sequence of the standby LED that you indicate is correct, if the source sends 24 volts to the inverter of the lamps is running, here is a diagram but it does not have the source, can you upload the code of the source plate?
