A couple people were moving my 154-lb Sony 30-inch 16:9 CRT to
another residence and it got dropped a couple feet, hitting the guy's
foot to "cushion" one side of it. It fell on the heavy front side of
course. Minor cabinet scratches. It powers on, receives OTA stuff
very well! No broken glass!!!

Problem: palm-size green blotch in upper left corner with a matching
red blotch in the upper-right corner. My handy little degausser coil
cannot make the blotches go away. Picture otherwise is very crisp and
clear. Audio is fine. Hope aperture grill is OK.

Any hints on what to physically look for once I get the back cover
off? Of course, it's just out of warranty.

Degauss coil unplugged is my hunch...I just don't know what it looks
like, or something else with some heavy mass that could have shifted
when the set got dropped face-first.

Thanks,

Sorry to tell you... It's toast! You will have to live with it.
The aperture grill (which is inside the CRT) has shifted or bent.
There is no way to perfectly repair this.
As another person mentioned, small magnets taped to some spots on the
back of the CRT might help, but the CRT is irreperably damaged.

So how's your friend's foot after it "cushioned" the set?
