I seem to have the washed out pictures on my Samsung LN37A550P3FXZA. And have tested my T-con board voltages. My problem is that the board does not give the numbered sequence so I can easily tell if they are increasing/decreasing in order. So I number them myself as in my attached pictures and the voltages are:

From this forum, I guess my T-con is bad. Why are the numbers so different with and without the picture? Should they be different? Can it be anything other than the T-con board? If I choose to replace the gamma chip, is that most likely the ONLY thing that can be wrong with the T-con board? Otherwise, the TV works as normal, and the MENU is aligned straight, no jagged edges, but has unusual colors too. Has anyone had success buying from the many available Samsung T-con boards available directly from china? Please advise.......
Note: I recently stayed in a hotel in Rochester MN, that had ALL the same model, 2008 Samsung TVs in every room and lobby and are still going strong....
