A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

If they are on left and right sides look from front of set--if not Google the model for a service manual which will have a pictorial showing which is which.

I do not have the schematic, but have a testing / troubleshooting guide for the 60PC1D 1st and 2nd generation, which gives some good insight in organization and functionality of the power boards.
This is what we ourselves step on when repairing - LG often does not publish schematics for power boards and sustain boards.
