My local service engineer insist they need to dismantle the whole unit and take some measurements to be able to judge if it is even faulty by their criteria. It sound to me like they think there could be some kind of a voltage adjustment to fix this.
I´m suffering with same problem.

Service took set week ago and they still waiting answer from Panasonic what to do.
Seems that there are few units which are more sensible to IR/burn-in than others.
Had also two Panasonic plasma models before ST50 and not ever this kind of problem.
At first Panasonic (Finland) said IR not belongs under warranty, but like you said it´s really not normal that you have to clear screen 100 hours after few hours gaming or watching channel where is bright opaque channel logo.
Made reclamation to customer protection and now service examine is it faulty (out of factory specs) or not.
If they still not accept to repair it I´m going to take this case under customer law processing.
edit:
Just got e-mail from service that Panasonic agreed to fix my set by replacing new panel

So there´s no sense to drive cleaning 100 hours if you have burn-in just after few hour TV watching, panel is faulty and belongs under warranty.
