taobao is a great source, and to my surprise, such a big screen is actually quite cheap, cheaper than most mobile phone screen!
Before the replacement.
The seller was nice enough to request for an image of the back of the tablet, so as to ensure everything works well.
Make sure that it could be turned on...
The disassembly is easy, much easier than replacing the screen of a mobile phone.
Pulled out the components... the connectors were quite big and so it's not difficult at all.
Q.E.D.
