Here’s the LCD screen/digitizer assembly.

The LCD screen is glued to the back side of the front bezel frame and can be removed relatively easy.

The digitizer, on the other hand, is glued to the front side of the bezel and removing it can be a real pain, very similar to replacing cracked glass on MacBook Pro.

I searched on eBay and found a few digitizers available but no-one was selling it with the bezel.

After some consideration, I decided to replace the entire LCD/digitizer assembly as it shown on the following picture.
