Good afternoon fellow maemo users!

I am trying to replace my n900 digitiser following the service manual (my touchscreen is scratched).

Unfortunately 3 out of the 6 screws on the back of the screen, through the slider assembly, stripped immediately.

What are my best moves? From the service manual I cant see which parts are effected if i try to remove the screwheads.

I doubt Nokia Care is willing to do something about it, its my own fault. Do you guys have any insights?

A counter-threaded screw remover set after drilling into the screw head is your best bet as it causes no damage besides to the screw. Can u get new screws as you will need to?

Give the bread to the bakers, is a saying in my country meaning let the pros do it.

How do you get new pros then, if you just pass of the task to someone more experienced?

This is why I dislike sayings. Whatever wisdom they may convey is lost on most people actually using those sayings.

And in a more practical sense, who the hell is he going to find who'll fix up his N900? The places around him might not have the expertise either, or be unreliable, or charge too much.

Well its not like i cant use my N900 now, its just a bit scratched. I see this like my little project. I am sure pro's do it better, and I'm sure pro's werent born with skills as well :P

Yeah i know those tools exist. But do they work on such small screws? Do you know which parts i need to change when i remove the heads, but not the screws?

From the lowres service manual I think only the cover ASSY and the metal frame? If that is the case I might risk it, if i need to change more parts I think I will have to live with a scratched screen

Thanks for thinking with me guys!

Hi everybody, i'm gettin' the same problem as NlChris.

no way i am lettin' those 3 remaining screws out of their holes.

Tried with wd-40 oil, got the phone to a watch repair professional, but all i've got is frustration and the screws head being "eaten" by the screwdrivers.

obviously, my brand new lcd came with a tiny chinese ph 00 screwdriver, which is not a professional tool.

anyway, keeping in mind the serious tools the watchmen has, i really don't know how am i gettind rid of those screws.

I'll beg your help, any answer is deeply appreciated.

maybe you can use some solder or glue of some sort to attach the screwdriver to the screw? or use a dremmel to cut a notch in it so you can remove it with a sharpened screwdriver.

Did the watch repairer try a screw remover (see my post above)? They come in different sizes and I imagine they make 'em for watch sized stuff too as they really are the only "non-destructive" way forward (unless you are lucky with one of CreamyG's suggestions). I used one for a very small screw on a laptop.

I note in Nokia's service manual they emphasise not to reuse screws after disassembly - I guess they know they are "soft".

Have you tried using loctite to glue the screwdrive head to the screw. You will need to use some fixture to hold it still while the loctite dries (or use loctite primer if you can find it).

You wont believe how strong loctite is - I have used it to hold metal shafts onto each other while I turned them on the lathe. And in that case, the cutting forces did not break the loctite. Loctite red should do the trick, but be careful you dont end up gluing the screw to it's hole or else you will just make the problem worse.
