A $125 waste, IMHO, he will tell you immediately dead panel. There is no way within any reasonable possibility for it to be another fault.
where are you getting these statistics?
Practically the only panel failure for PDP is the stuck vertical line as demonstrated here, and a quick search will show this to be rare.
For many new TVs it's easier to replace whole panels or TVs for single faults rather than repair them - even if component cost is highest.
The statistics are estimates by myself. I have seen too many LED-LCD and LCD TVs with bad panels. About 15% of the TVs I see on ebay, craigslist/gumtree/etc, avsforum, badcaps forum and personally are bad panels. Bad plasma panels, 1%, and mostly minor, "you could deal with it" faults, pretty typical is a single pixel line which mostly blends in with content, only popping up now and then., still very annoying but ok as a bedroom TV etc.
Again - Plasma can fail but 99% of the time it can be fixed, where as LED-LCD TV can be uneconomical in a great deal of cases due to panel faults.
