Just recently, I noticed on my Toshiba 50h81 the left grey bar when watching 4x3 material (I normally use wide 1 for TV, but was switching between modes when I noticed this) bends outward at the bottom. The right bar is fine. It was not always like this, just a few weeks ago, the gemometry on the sides was dead on. I have not checked the screen with the Avia disc to check geometry against the patterns recently (it is loaned to a friend at the moment) I'm aware that if this is a case of the geometry drifting, it can be adjusted by either 56-point or when the set is ISFd. (The set is only 6 weeks old so. I plan to have the set ISFd later this year, but am too nervous to attempt a 56-point on my own at this time. I have used the manual 9 point to touch up convergence drift as the set breaks in.) But in Avia's white balance section, I remember it talks about the two bottom vertical lines bending is a result of an inadequate power supply. This could be the culprit because it has been 92+ humidity in the suburban Philadelphia area this past week and there could be a strain on local power due to air conditioners on max. This would explain why it was fine for the first 5 weeks and only recently display the outward bow at the bottom left. If inadequate power supply is the culprit..is there a solution? Thanks for any advice or help.
