Well, Ive been to my local phone service station (not Nokia Care though) recently (they sell n900s and other Nokia's high-end devices). They told me that there are no third-party screens for n900 and the only way now to fix it is directly in Nokia (Nokia Care I suppose). I should either wait until some screens that fit the n900 appear on the market or fix it at Nokia.

It leads to the conclusion that a DIY screen replacement process is impossible as for today due to lack of suitable screens for n900 to purchase.

It is getting worse and worse.... State of LCD leakage for 20.03.10:
