Hello TF-Forum People!
I wanted to post a description of a successfull LCD Screen replacement (I didn't take pictures unluckily...), which hopefully will help future Tf300 owners to repair their tablet.
Recently the LCD screen of my TF300 cracked for unknown reasons (cat, dog, wife?) while lying unattended on the floor... After the first shock, I started to browse the internet in order to find out how to solve the problem (RMA was for severeal reasons no option). As It seems, at the moment there is only little information on this issue available and only one thread in your forum showing the innards of this type of tablet.
I ordered a new screen from here: Asus Eee Pad Transformer TF300 TF300T LCD Screen Display Panel Replacement
After 2 weeks it arrived at my place and was nicely packaged (only problem was, that these guys didn't put the invoice on the outside of the package, so I had to show up at our customs-service).
Opening the TF300 is fairly easy, robust fingernails will do the job. I strtet at the lower end of the tablet, and lifted the plastic back-shell over the corner of the screen. When you do this you have to be a bit careful at the earplug connector and the hdmi-connector, here you hve to bend the shell a bit more.
Next you have the insid in front of you and you need to remove all the stainless srews including those from the digitizer PCB, but not those six from the dock-connector.
Then you unplug the screen (easy) and the Digitizer cable (orange plastic on the lower right side). Before removing the digitizer cable have a close look at it, there's a white line on it showing you how deep this cable has to be inside the plug/connector. When you reassemble everything you have to push it back to the same extend, otherwise the digitizer doesn't work. This can be quite hard to achieve, because the cable bends easily, so applying the apppropriate force is quite a challenge...
Now before you can separate "moterboard" from screen+digitizer, there's a couple of tapes you'll need to loosen. One is on the lower left of the tablet (close to the left dock-holder). In my case it was black, covering a square hole and sticking to a little magnet, which was glued to the old LCD screen. The next two tabes can be fund under the digitizer PCB on the right side, underneath the hdmi- and sd-card-dock.
Now you can lift of the computer-part of the tablet from the screen/digitizer unit.
Now comes the worst part: separating the old screen from the digitizer...
In my case I first opened the metall frame of the lcd and lifted out the old brocken lcd. By doing so, I got good access to the other side of this frame, which is glued to the digitizer via double sided tape (damn you asus, why are these guys using a dozen screws to connect digitizer/lcd to the computer but the glue the lcd to the digitizer?). I carefully pried of this frame starting from the oposite site of where the digitizer cable is located. Although worked quite well, I had to destroy (bend) the frame in this process (and it cut into my fingers...).
Next I removed the last bits of the double sided tape, put some new double sided tape on the metal frame of my new screen. I used this kind of tape you get at hardware shops to glue a carpet onto the floor and cut it into apprpriate shaped pieces. The I put the new sceen to the place of the old one, reassembled everything in the reverse order (had some problems getting the digitizer cable into its connector) and tested everything.
And indeed, everything works fine, and I'm happy again
If you want to do the same, I would suggest, instead of tearing out the whole old lcd-screen unit, to carefully remove only the LCD+LCD-PCB itself, leaving the old frames intact. This way, you don't have to fiddle around with the tedious double sided tape. You can disassemble the old LCD (which is anyway broken) first, so you can learn, how this thing is assembled.
I hope you will find this manual informative and helpfull to repair your device.
