LG Plasma 60PZ570W logic test mode?

[PowerAmpFreak]

Hi all
Got this plasma, LG 60PZ570W with no picture, all voltages seems alright.
Want to put this set (if possible) in testmode by logicboard if it has the ability to generate test waveforms/bars.
Please see attached pics.

not sure about the whole procedure, never done it. may need the lvds disconnected from main, may need the power lead disconnected and jumpered to force TV on from main too. Someone will know but pretty sure jumper the 2 pads highlighted in the pic on the ctrl bd

That looks like them.
On every LG since the early models, LVDS has to be unplugged to enable test mode.

Will unplugging LVDS cable automatically enable testmode?
Or does the powersupply needs to be "jump started" ? (Like Samsung)
And of course short the nodes in the pic.

Keep mainboard connected to PSU, but remove LVDS from it--or control-board, jumper the two points and use normal on/off to fire up set.

If panel and control-board good, you'll have test-patterns refreshing every second or so.

Thank you guys.
It appeared the "panel-boards" are OK, but mainboard is bad.
When activiating testmode it generates nice patterns.
