The plastic tabs of the clutch fit into slots that end up holding the clutch in place. The idea is that you need to slide the clutch to the right to free the plastic tabs from the metal slots in the LCD frame.....then you can separate the clutch from the frame.
The tape is very sticky and the glass is very fragile but at the same time fairly flexible.....I ended up breaking the glass ans it turned out to be a mess picking up the shards....but in the end a new glass is not too costly. the implication is that heating melts the glue but it is really just double stick tape.....there are some "youtube" videos that are worth a look but I would suggest using guitar picks and not a putty knife which creates a point load that breaks the glass....wear safety glasses!!
It's not to clear but there is a piece of spring steel that rotates away from the main (circuit board side) of the connector....this piece sort of hugs the parameter of the screen cable locking it to the circuit board...both arms wrapped around your brother....looking closely (10x magnifier) at this cable one of the gold connections is slightly oxidized---my display arbitrarily flickers and this symptom is lessened as the temperature increases...I suspect this is the cuase of the screen flashing on/off
