Just pull from the side indicated by the arrow.

Remove battery, memory card and 5 screws.

To avoid damage, disconnect the screen, the connector is opened pulling with your fingernail the hinge indicated by the arrow.

I like to keep it upside down at it's normal position in the front panel, this will keep the screen and front panel free from dust. Dust is a pain to remove afterwards.

Remove the remaining 2 screws (indicated by green arrows).

The PCB should come out easily.

You may have to pull from the battery connections to avoid breaking them if you pull only the PCB (orange arrows).

Pay special attention to the speaker cable, it's very short and fragile.

If the PCB does seems to be stuck and does not come out, maybe you forgot to remove the memory card (pink arrow).
