Plugged in my charger yesterday and the upper right screen is illuminated but has nothing reading on it as the other 3 screens do. Anyone experience this or know how to fix it?

Thanks

It sounds like the disply driver or the lcd is bad. Is this unit a new one? If so then send back to Hitec to get it fixed. There is nothing you can do inside the unit itself. The lcds really cant b repaired t

I purchased it second hand. Guess I'm down to 3 ports now.

Ive seen this problem on many of the X4 chargers. Sees to be a common issue that Hitec doesn't want to address.

Send it into hitec, they are more than fair with repairs.
