Replacing lcd screen on s400

[cosxp]

I broke lcd screen so I got spare part for replacement.
I opened up camaera and it seems I'm not able to detach
lcd panel from camera.

I followed instruction posted on
http://www.cl.cam.ac.uk/~jo262/miscellany/broken_lcd_cracked_screen_canon_sd-300_sd-200_ixus-40_ixus-30.html

but my s400 lcd part doesn't look same as it described on above instruction
and I can't detach from camera..

Anyone had experience doing this and can give me some help ?

Thanks in advanced.
