    No red, R3355 surface mount resistor open on
    CRT board, now red is fine, but if G2 is even close
    to normal setting, CRT arcs blue in the neck, lower
    it, & it stops, I two large bars of "blurryness", can be
    seen onscreen. Pix is very poor, unless G2 is set close
    to normal, but then it arcs. Socket, & CRT board are
    fine. CRT bad I assume? My Sencore CR-70 CRT
    rejuvinator book doesn't list the pix tube. The CRT #
    is A90AKB50X04 (V). Anyone know the settings for
    this CRT, I'm not sure what exactly is shorted in the CRT,
    but what about making up a couple of windings from the
    IHVT ferrite? Sky.
     
  2. Have you learned to use the universal adapter? You can possibly get
    the 5 electrodes identified from the CRT board, and do the CRT with
    that.

    I only have the "super common) #3 #4 adaptor for the
    rejuvinator. Thanks, for the input. Sky.

    Sky,

    This is very common on zenith CRTs but can happen to any. Tube is
    gone. RCA used very similar guns (standard socket, not small one)
    across many RCA CRTs, treat it as such on CRT rejuvenator.

    Cheers, Wizard
