21fbp22 crt test question

[timmy]

hey guys i tested the 21fbp22 crt from that silvertone tv i just got and it was dead all the way around no meter movement, no nothing but is it possible to rejuvinate the guns and have them come back strong. my bk tester says 200 or more is fine however the green gun came up to around 340 the blue came up tp 260 and the red came up to around 160, is the red the most criticle of the 3 guns. the life test came back very good and the final gave me the 2 neon lights telling me its now good.could it have come back that strong, well except the red which im going to try that gun again maybe on the next setting. any ideas about the red gun if it dont come up any more like keep the red adjustment lower, well to prolong that gun.
