A little update, it seems that even after reflowing the solder under the main chip on the mainboard on this TV 3 times it still refuses to power on, but the good news is that I know for sure that a mainboard failure is definitely what's wrong with this TV because I disconnected the mainboard from the power supply board and jumpered the test pattern generator jumpers and the TV Screen lit up like it was supposed to, no bad pixels or anything, which means everything else on the TV works like it should just not the mainboard.

And since the TV didn't come back to life after 3 attempts at reflowing the solder on the main chip on the mainboard I'm kind of wondering if the main chip itself isn't bad which if that's the case I will probably just have to keep an eye out on ebay for another replacement mainboard for this particular model of TV and hope that the replacement board still works.

UPDATE: I didn't have to look for very long as a mainboard for this tv just showed up on ebay for sale today for $60 or best offer and I submitted an offer to the seller, so hopefully I'll be able to get this TV up and running by the end of this week if the seller accepts my offer.

Also I looked up a manual for this TV on the LG website and apparently this is a 3D SmartTV!
