LG 50PG60 Main Board

[mmartell]

Set was priming when plugged but no pic and non responsive to remote. Jumper on Logic board comfirmed good test patterns.

Main board is part number EBT51299502 which is rather expensive. Does anyone have any knowledge of failure modes for this board or have knowledge of a reasonably priced substitute ?

You are correct Reecey! Some time later after I posted I tried again with a copious amount of hair dryer heat (I had tried when I first cracked the back off) and she fired up and works as normal.

Now what ? Can't say I've done a successful reflow - a little gunshy from when my first attempt at reflow caused a solder ball to come rolling out from under the chip lol. Any suggestions ?
