From the manual:
A compatible 3D source device connected to the
TV via HDMI and outputting a 3D signal in one of
- Frame Packing 1080p/24-Hz or 720p/60-Hz
- Top-Bottom 1080p/24-Hz or 720p/60-Hz
- Side-by-Side format, 1080p, 24/30/60-Hz;
- Checkerboard format, 1080p, 60-Hz; (lower resolutions may be supported but will not fill the screen)
You do not need the adapter anymore as it converts all of the formats your set supports to checkboard. You can now sell the 3DA-1 adapter as you don't need it anymore. As for the scratches, look up the parts online. You will need a replacement screen - you can find them but they aren't cheap.
Here you go:
I imagine you only need the outer screen.
