Does anybody know what this HDMI IC pin does?

Hey guys,

Have another question. Does anyone happen to have or know the datasheet for the HDMI IC for the PSP Pro? I ripped one of the pads off (see blue circled area) and of course it has a trace going down to the APU. Just wondering what it may do and see if i could possibly get a way with not fixing it. See my picture for the referenced pin.

Also. If a fix is required, what would be the best method for repair? These QNF chips don’t have much to really solder to and of course the pad is underneath the chip. Thanks!
