I noticed that too. I like my T931’s build quality. 2000s solid state TVs have PCBs that are as thin as two sheets of paper.
The one thing I do not lile about the T931 (and the T933 as the same design) is that it doesn’t use DC reinsertion, but instead uses partial DC coupling of the DC bias from the video detector. This causes inconsistent black levels, especially for super bright scenes, which cause black crush.
I am tempted to add a diode clamper to make brightness more consistent between scenes.
