Not to say replacing the display screen on a Fuze isn’t possible, but there are some obstacles . . .
1.) Finding one to replace yours with. Your best bet is to buy a DOA unit off somebody on eBay, for example. There is no outlet for replacement parts. Of course you run the risk of that screen being dead too.
2.) Actually replacing the screen. Yes, it has a ribbon cable connector so it just plugs in but . . . the wires in that cable are smaller than a human hair, and there’s a bunch of them. The ribbon cable is very fragile and the wires within it even more so. So likelyhood of breaking one or more of them during the removal or replacement process is quite high.
You might be beter off trying to find a working/refurbished one on eBay or some other outlet. Of course, being discontinued for so long and a very desirable palyer (compared to the newer models) means those who have them for sale will be asking a premium price for them.
Good luck . . . let us know what you decide and how it goes.
