Hi all,
This problem does rare its head occasionally here in Oz as well. The problem can be a number of causes...one its simply the screen on the handle needs replacing....which Nokta supply the whole middle shaft which holds the handle and screen/buttons complete......this is the replacement part.
Its very simple to check if the dealer attaches the faulty handle to a known working unit...if the handle functions correctly.... the main board from which the handle came off is faulty in most cases. Its also possible that the plug where it attaches to the main board has connection issues. Its also best that the customer sends the whole unit back for diagnoses, and not just the handle.
As the repairer for Nokta/Makro Australia, iv now repaired a few suffering this failure.....there is no soldering needed for this and many other repairs....they are just simply plug and play setups making them probably the easiest detector to work on as all parts that could fail...are plug and play. This makes repairing the units very fast and simple. Including accidental damage caused by the customer...ie broken screens ect ect.
For any dealer in the USA...they are very simply to repair if you have the parts....and as a dealer, you should consider stocking all the necessary parts to keep your customers happy. Main board R&R can be done in less than 15min. Total dismantle about the same time. Fors gold, Core and RACER.
Id hazard a guess and say the FG+ and new Gold RACER will also be plug and play and have many parts interchangeable due to design similarities...very simply and nothing to stress over thinking you need to hire a technician for repairs...not necessary.
They are a pleasure to fix repair mend when the need arises. And in most cases, the customer if local to your shop can come back in an hr or so and pick it up should he/her present you with a failed unit.?
I personally check the operation of each and every machine that leaves our store, but that does not mean a failure wont occur in time. It simply allows me to catch any that maybe DOA, or for any damage that occurred in transit from the manufacturer, and the possibility of missing sundries.?
