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
