You should focus on this area.
Take a piece of tape or string from the exact middle of the fault area. Pull it over the TV frame; it will intersect one of the metal plates which connect to the panel itself.
You should then turn the TV off (unplug it) and leave it off for at least 5 minutes. Place one hand on the metal frame of the TV to ground yourself properly. Try to touch the frame while working on the set.
On the faulty part (if you are not sure do several in the same area) remove the screws holding the clamp down, unhinge the connector, bend the connector up, re-insert the connector, secure the latch (the cable should be completely parallel to the latch; no flex is permitted), screw the clamp down (very, very important, as if this is not done, the plasma panel driver will overheat after some time, which is a non-user-replaceable part) and power the TV back on.
This should hopefully fix the issue.Edited by tom669 - 7/2/13 at 2:37pm
