Jeeze, that would cost more to repair than getting a new meter. Certainly more than the Brymen Dave is selling - and that is a much better meter than the Extech 470, IMO, even though it doesn't have that IR thermometer (IR thermometer is maybe a $15 on eBay).
Sorry for the French Digikey site, I thought it will send you to the US one. They ship everything from US anyway. I wasn't able to find that exact MOV model stocked, it seems to be an obsolete part. Good that you have found one.
BTW, both my Extechs were not really "recent" - I had them for several years now too.
