Have Panasonic send the tech back to your place. Clearly the fix was inadequate or improper.

Please help me with broken/fixed Panasonic plasma
Hey everyone. I have a problem and need some help.
I own a Panasonic TH-58PZ850U which was manufactured Sept. 2008 and purchased by me Oct. 16th 2008. On July 14th 2009 my picture stopped working in the middle of playing XBOX 360. I received no display. Not even the TV/Video display or Menu would come up. The set itself powered on and the power light did not blink or indicate an error code (to my knowledge).
So I called Panasonic and they had a service tech from DTR Technologies here in Denver to come look at it. Turns out they needed to replace a board. Now my TV was mounted to a table so I had to take it off and set it against the wall so that the tech would have access to all 4 sides. This meant that I had nothing to connect to it that could be used as a test signal (no dvd, cable, xbox, etc) when the tech finished his repair.
I was not home when the tech arrived but my neighbor was and he allowed the tech to enter and replace the part. The part he replaced is written down as an 'A-Board'. I am not sure what that is and I can't find any info on it when googled. I called DTR Technologies and asked the name of the board and they again listed it as an 'A Board'.
Now when I return all my setting to what I had before (Everything was just slightly over 50) the screen looks SO DARK. The picture is not nearly as good as it used to be.
My questions is this... Does this board require the standard 100 hours of break-in or is it the screen itself and the pixels? Can anyone recommend ways for me to fix this. As it stands now, I have the tech coming out tomorrow morning to look at it. I am sure he will say that nothing is wrong and that I will just need to turn up the settings. Well I don't want to torch my plasma. I don't feel like I SHOULD have to since it looked AWESOME before.
Any help would be greatly appreciated.
Sincerely,
John

I make it a point to be there when any repairs are made to electronics or appliances....As for me,any complications arising can be dealt with on site...
Believe me,in the neighborhood I reside in....and talking electronics or such with my neighbors,I would never ask one of them to let a repair person enter my home while I am absent!

I don't see Panasonic enough to know, but the "A" board is probably like a Main board or Digital/Signal board. There is no break in for this type of board and you won't torch anything just by turning the settings up. The tech should have hooked up a source after the repair just for testing purposes... BUT-
Did you have your Tv calibrated at the service menu level? Do you have any calibration data showing pre-repair numbers vs post-repair numbers for things like grayscale or brightness? To say that it doesn't look as good or looks darker is highly subjective. Unless you have two Tv's side by side with the exact same source material on the screen simultaneously, there is no way you can realistically claim that one looks different than another. Also, how can you expect a person to be able to recognize that the picture looks "so dark" and "not nearly as good" without ever seeing it pre-repair?

Hammerdwn,
I did not have it professionally calibrated. I was waiting to do it early 2010. I also do not expect the tech to know what the picture looked like before. I am not blaming the tech. I was asking if this is normal. If the board needs to be "broken" in.
My wife agrees with me that the picture seems unusually dark as compared to what it used to be. I did not write down my setting before but I know that I never went above 60 in anything for fear of torching it or making lessening the life of the set. I recognize that setting the picture modes above 60 will not lessen it but it is my own thinking.
Also, my neighbor has been my best friend of 15 years and although he doesn't know anything about electronics I asked him to be there so that we would have the TV fixed before we went out of town. I just got back this morning and can already tell the picture isn't good. No matter what source I use (cable, xbox 360, Blu-ray) the picture is not what it used to be. Perhaps if the tech tomorrow can not fix it or put a new board in there then I will have to have it professionally calibrated sooner.
