[TechAssist] Re: toshiba cf27h50 shadow mask

If that is the case...
Then the Tube is bad.

If the purity problem is not to bad....
AND
You have not messed with the purity rings on the neck of the CRT. Then you
can try glueing small fridge magnets to the bell of the crt with Silicone.
(Use tape to hold them in place tell the silicone sets.

Other then that....I got NOTHING!

Good luck, God Bless, Happy Holidays
