Hello everyone, I have an F&U Android TV FLA4220UH main board 17MB170 and panel VES415QNDR-N2-N41. The LED was flashing and there was no power on. I upgraded it with a firmware of FLA4320 TV I found in the forum. The TV turned on, but it shows a double image, which means that I upgraded the TV with the wrong firmware. So, there are two solutions: either if someone has the correct firmware to send me, or if someone knows how to enter the service menu to change the panel settings and get the right picture. Thank you in advance.
