I have disconnected the front display. It is now OK. But problem remote not working. I think that said IC became faulty.
in general, what I did was solder the 10-pin U1 Vcc, turn off the power from the ET6226M chip - the display, the LED and the button on the front panel do not work, but the receiver is controlled from the remote control
here is a typical circuit for turning on this microcircuit, and with the arrow I indicated which leg of the microcircuit I had unsoldered from the board, removed the power from the microcircuit
Good luck friends, don't be afraid, everything is in your hands!
