If you ask The Cheecky Monkey nicely, he might do you one of the best repairs you could get.
Honestly.. the iron must haveen way to hot or you held it on far too long to do that sort of damage and IC seg soldering isnt for the faint hearted.
TCM's guides practically taught me to solder...Ive seen his repair work before on Xbox 1's and PS2's and its immense.... Getting him to do it probably the hard part
No offence to any of the others work who has posted here.
I second that mate. some of his guides have been a massive help to me too.
