@hulldj, not sure what liquid flux is? i used thermal compound from maplins, i fixed this the same night, took about 2hours, but 50mins of that is waiting for the board to cool down, its still working, just hope it continues until after xmas (when the logitec g27 makes an appearance) last fix worked for 3months, if i can get 2il be happy,
+dont be scared of the heat gun just make sure its constantly being moved/rotated & not left to heat up a certain spot for too long,
follow this tutorial, its impossible to go wrong, the hardest thing i found was taking off the very 1st screw

(which holds cover in place), drilled it out & now my cover slips on/off, (which is actually a good thing, cos it will need to be removed each time its repaired)
