Fixed Board Lens

Convergence fixed, but now my TV has a dot on the screen?
I did some checking and found how to fix the convergence on my rear projection TV by replacing the convergence IC's however after getting everything put back together and the convergence adjusted there is now a cyan or green dot about 1cm in diameter slightly left of cent about 2/3's of the way up from the bottom of the screen. The picture looks great except for this dots which is annoying to say the least.
I checked the back of the screen and the mirror and they are spotless so I am assuming that something must be on or in one of the guns or lens assemblies.
I have read on some boards of others having fixed their convergence issues then getting dots like this one as well, but have been unable to find any answers as to the cause or fix.
Fire up the TV set...remove the front screen. LOOK inside the RED picture tube. You'll see a black spot BURNED onto the phosphor...
Then take a look at the green and blue just to make sure you didn't burn those either....
Most likely caused by a sudden power loss, like unplugging the TV set while it was running, losing power from a power interruption.
You'll need to at least replace the RED picture tube to make that problem go away....
