First time poster, long time AVS reader.
Helped my father research a new TV (to replace an aging 32" CRT); I suggested the 60" A2020. He pulled the trigger on it a few weeks ago and has been thrilled with the image quality -- HD DVD and Blu-Ray movies look stunning on it.
Unfortunately I noticed a couple of issues. First, there appears to be a slight convergence issue -- the bottom and right side of the screen have a visible green cast, but only when black is being displayed (ie, Letterboxed/Pillarboxed content). It's barely visible on the right side, and is practically invisible altogether when watching anything other than a black screen. I understand this is quite normal for these TV's and it's not distracting, so no biggie.
The other issue is the one I'm more concerned about -- a dreaded green blob in the middle of the screen, with a purple/magenta discoloration around it (like a green hole in a purple/magenta donut). It's most obvious upon a cold startup of the TV, and appears to dissipate after the set has been on for about 2 hours. It's difficult to spot when viewing something other than a mid gray to white screen, but you can still pick it out if you know it's there (until it's pretty much gone after the 2 hour mark).
Should this be a cause for concern? As a precautionary measure he's called up Sony and someone is going to come over and take a look at it. Is it normal for the "green blob" to take a couple of hours to dissipate? Anyone else with an A2020 experiencing the same thing?
Oh, the set has a Manuf. Date of Feb 2007.
