LG Plasma. No picture but sound.
2 weeks ago my tv started shutting off after 15 mins of use. When I would turn it back on I wouldn't have picture but have sound. If I left it off for about 30 minutes I could turn it back on again and have picture for another 15 minutes.
Since then, I have replaced the power supply, logic board and the y sustain.
I did not replace my buffer boards, I couldn't find any shorts on them.
Now my tv turns on with no picture and just has sound, but no longer turns off after 15 mins of use.
I have done the test where I unplug the y sustain to see if I still have sound and I do. Then I did the test where I unplug the z sustain to see if I have sound, and I do. So with both sustain boards unplugged I still have sound.
