I have LG RZ-26LZ50 it has the worst motherboard what I have ever seen.
So many bad caps, if u want to make it last long change everything. lol
Just located my bad cap area; it is the place where psu cable is connected.
Did 5 test runs, using hairdryer to get them going, no stripes when caps are heated.
So I will change them all. Also if u measure the smd caps they are failing also. LG great MB!!
