LG 60pn5700 No display.

Hello i have a LG 60pn5700.
I have checked all my voltages:
VZB: 115
VSC: 148
VS: 203
VA: 55

I have also checked autogen_ext. I get each indvidual color and i get the scans but i do not get actual color bars. The tv acts like it is powered up without autogen_ext jumpered but gives no output. Any thoughts?

if you are getting test patterns, then it sounds like you have a main board fault.

Thank you for your reply. Unfortunately i cannot seem to source that particular mainboard.

being an lg, there is a good chance that it is the solder joints under the main bga chip. you could try doing a reflow. what have you got to lose?
