Thanks friend jomi, it is only the tray that rotates the discs that is not put in its position, as it does not return those millimeters that should have a new belt wash the tray and I returned to lubricate it rotates well but not in reverse
Even when the tray comes out it does not fit in position 1 and 2 and I have to touch it with my finger back and it looks good {there the LED stops blinking}
I have read that the problem is in the dish fwd and dish rvs or dish sens controller, the motors have 10.9 ohms and lubricate them
