Ford Explorer Radio Display Repair

I have a 1998 Ford Explorer and the display has gone out (very common for this vehicle) even though the radio works fine otherwise.

I have found a number of sites that will sell you either parts or instructions on how to repair it. From what I understand it is a very easy repair (it involves replacing some resistors I believe on a board) but I need to know what exactly to do. Has anyone here ever had any experience with this type repair and would like to share it with me so I can fix the radio without having to pay someone for instructions.

Thanks
