After moving house, the convergence has gone out of whack, but when I try to adjust it, it seems that the crosses do not move at all, therefore it cannot be re-converged. It seems as though there is no power to whatever makes the crosses move. Any answers?
Shuttle 83 - Projection TV tubes do not have shadow masks and therefore do not require degaussing.
I agree - get an expert to fix it as you can make more damage than you cure if you don't know what you're talking about.
Two things may have happened. First you may just need to degauss the CRTS. Let me explain when you move your TV you often cut across flux lines (magnetic lines of force) these have then tendency to magnetize your screen mask (a metal component in the CRT that slows down electrons) and cause what is sometimes misdiagnosed as a convergence problem. All that has to take place is a once over with a degaussing coil and the problem is fixed. The other thing that could have happened is the your convergence correction amplifiers have gone bad. This will require that you replace both modules (STK392-110). If you have a background in electronics you can perform these tasks, however if you don not have a background in electronics, I would suggest that you contact a qualified TV repair shop to service your TV set. I hope this helps, Thank You, Shuttle83
Press the MENU button on the remote.
2. Press 3 to select the Screen option.
3. Press 4 to select the Adjust Projection TV option.
4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).
The green pattern is fixed. The red and blue patterns are adjusted to
the green pattern. The Red Convergence appears first by default.
5. Colored cross-hairs show the current adjustment position on the
grid. To move the cross-hairs to a different position, use the
CH+/- buttons on the remote to move the cross-hair highlight up
and down, and the VOL+/- buttons to move it right and left.
6. Use the arrow buttons to adjust the red pattern. Each press of
the arrow button makes a slight adjustment from the center of
the cross-hairs - you can press and hold the desired arrow
button to make a faster adjustment, and then make fine
adjustments with single presses of the arrow button.
7. Press the INFO button to switch to Blue convergence and follow
the steps above to adjust the blue pattern.
8. Press OK to exit. You will be asked if you want to save the
adjustments
Yes Saves adjustments.
No Returns to the Advanced Convergence screen allowing
further adjustments.
Clear Exits screen without making any changes
Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

I am having the same problem. I hauled this behemoth, 1994 PTV520-AH01 52" Magnavox, up three tight flights of stairs and plug it in and everything is fine; all of a sudden the cable gets disconnected from me moving it and I plug it back in and the convergence is all messed up. I tried going into the advanced settings and adjusting the crosses but they do not move. This is a very frustrating problem! Can anyone expand on this? I mean on top of what Shutle83 already posted? BTW thanks Shuttle83 for the advice!
