Thanks Brian for the info.
This kind of problem occurs due to failure of buffer board mounted on bottom of rear of display panel, need to replace the buffer board where the vertical black bar appears on screen that would hopefully resolve the problem.
Please check following image link of this TV taken from service manual where buffer boards (C1 & C2) are marked and any one would be defective and causing the problem in TV..

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue.
I trust my input will help you out. Please feel free to respond if you have any additional questions.
