Sorry, but FixYa is an online only free resource and does not undertake physical repairs of any kind.
Leicas are very valuable and so you are highly advised to entrust repairs only to a Leica specialist. A documented Leica service history also helps preserve the value of your camera if resale values are important to you.
Wordwide repairs are handled by the Leica factory in Germany and I'd recommend that you
contact them directly, there are many excellent specialists who can do perfectly good repairs to older Leicas, but few are competent to tackle the electronics inside your late model.
I hope that this has been of assistance to you and that you kindly take a moment to rate my answer.
