Insert a plastic opening tool between the metal LCD frame and the front bezel.

Be sure you are prying between the metal LCD frame and the front bezel, not between the metal LCD frame and the LCD.

It may be necessary to reheat this area until the adhesive yields enough to insert the edge of a tool.

Use the flat end of a metal spudger to gently pry up the adhesive securing the metal LCD frame to the front bezel, taking special care not to scratch the LCD panel in the process.
