Larry its possible that your focus block assy. could be bad did you measure
the lead coming from the block to the 9-1674 (two wire plug) if I remember
it should be between 45k to 52k anything below or above you change it, I
have been fighting with one about a convergence problem and the last thing I
replaced was the focus block and that took care of it.

Hi Guys, this Zenith RZ56Z83D8 shuts down the tubes on bright scenes/scene
change, original complaint was dead, changed 9-1674 module, convergence
module
9-1690 failed 20 minutes after installing 9-1674, replaced STK`s, had no 16
v line,
found open winding on flyback, replaced fly, now G2 is too high, turn
control all
the way counterclockwise red & green still lit, set jumpers to disable,
turned up
each tube to retrace and then back down to extinguish retrace, replaced
jumpers
to normal mode and tubes come on very bright, and instantly go out, set
has a good picture when it`s running but obviously X-Ray protect is shutting
the tubes
off, any ideas or should I buy another 9-1674? Needless to say customer is
very pissed off at this point, your help is appreciated, Larry E
