I would run the test patterns if you can

Re: Lg 60PZ550 no picture
Do the auto_gen test by removing the LVDS cable and shorting two pads on the logic board, the tv should start by showing test patterns, if the image is good and stable the fault lies on the main board, possibly BGA issues on the main chip under the heatsink, famous on all PX and PZ plasmas.
Following the standard on LG plasmas, I think it's those two pads since the service manual nor the board itself shows where they should be.
