Hello, I am new here. I have purchased an advanced 6 car power base 2nd hand off eBay, it looks like new and the seller stated it had only been used a few times. My problem is when the LCD display is plugged in I cannot program the cars to the controllers in prog mode, nothing happens when I press the down button to change into the prog menu. If I unplug the LCD display I can manuallyprogram the cars using the actual power base. Does this suggest the LCD unit is faulty or the power base, is this a common fault can it be repaired. Thank you. Tony
