Lg 42 issue

[LEEDASH]

Hi forum,I have not stated model but will re edit at later stage,yet another faulty TV set,on switching the television set on,it displayed a pure white screen,then I heard a crackle,I then briefly switched it off incase it blew my electric box,
Left it a hour opened it up and noticed a couple of blackened out parts along with underneath the psu some kind of iffy soldering or is this normal for Lg,can I ask what would have caused this ? Was in dry storage

Firstly I would check the gamma voltages across the tcon board
but it may also be bad tab bonding issues

Checked mains fuse and other major parts for shorts using a DMM ?
