PCB, Power Supply Display Board, Expedite, Exchange. This is the power converter board that is located on the back of the display in the top section of the instrument. The most common symptom that this board needs changing if the display bask light goes out. If the back light is out, you will still be able to see the display information but it will be faint and you may need to look from an angle. Since this is an exchange part, you must return your old part complete with all components. If you do not return your part or you return it missing components, you will be charged as though you purchased a new part without exchange. If you do not want to send your old part back to us, you should purchase this same item as non exchange from us.
