Yeah TR / T1 T2 are the same apart from the revision number, well at least I’ve used screens from T1 in TR without issue and I can’t see any difference between LQ106K1LA01 & LQ106K1LA02, not from a users point of view anyway.
Funny thing was the first T1xp I got, (with the common rebooting issue), the screen looked poorer quality like it was suffering from to much gamma. When I fitted it in a TR it was fine so it must be poorer graphics on T series, or to do with the fault. Not isolated either because I just got another T1xp in yesterday and it’s the same with the gamma.
Anyhow as far as I know the sharp is the only screen that will fit, (it’s definitely the only one that is fitted as standard), and they are all X-brite or X-black. This is talking from my own experience so I could be wrong, but I’ve not come across another screen type for TR / T..
Might be worth double checking the Sharp part number(s) with him first to save shipping it to him and finding he only has TX type screen..
