[TechAssist] Re: Sony Mod: KP-51HW40 Blue retrace and shuts down

        This is one that had the bad crtS mostly built late 2002. ser # should
start with 90. Tap on crt's or just watch see if has a slight flickering,
solution is usually change all 3 crt and may have an extended warranty for
this. can be tricky as sometimes good for days and weeks then start flicker
again. impregnated coating flaking off the cathodes was sonys ex.

This unit will turn on with blue screen and retrace
lines and shuts down in 10 sec. Screen volts 400v on
blue screen, red and green 300v. Turn screen control
down for blue and it works. Swap red and blue screen
wires and the blue is ok and the red has faint retrace
lines but does not shut down. I am thinking screen
control block. I have changed caps and spark gap. What
do you think? Thanks Ben
