I'm having issues with my 960.. You know the black stripes all around the edges of the TV? the top black part seems to have dropped 1/3 of a inch, & the picture is shown above the black stripe (or borders) while blocking some of the picture. & on the top left it looks like the black stripes cross each other, looking like a cross.. Is this a geometry problem that can be fixed. I only went into the service menu to fix the landing. I been doing this for 2 weeks with no problems. I just noticed this last night.

This may be the blanking shutters. The shutters are used to cover unwanted scan lines or scan line start/stop anomalies.

I believe the following 2170D-3 service codes control this.
HBLK (horizontal blanking shutter) 0-off, 1-on (Toggles the left and right shutters.)
LBLK (left blanking shutter) 0-63
RBLK (right blanking shutter) 0-63
VBLK (vertical blankiing shutter) 0-off, 1-on (Toggles the top and bottom shutters.)
TBLK (top blanking shutter) 0-15
BBLK (bottom blanking shutter) 0-15

You already know the next part about writing things down.

Good Luck
