Blue tube decided to drop a neck!! Waaaaah!!
Happened while TV is on displaying windows (underscan, also had to be
set so image brightness not that bright or else unit blanks out.) via
S-video on video card's video out while I was getting around to get
tools ready and take apart TV to look closely at the blanking problem.
Amazingly clean break.
That darned blue CRT was first replaced (1) last winter then followed
red and green in late spring to stop shutdowns which didn't work out
but fixed the grey scale problem.
I was told this kind of neck falling off usually cauased by beam
hitting glass but I don't see this happen like this??? Blank is very
instant. OFF like snap, if blanked too long, TV shuts down.
Besides, I had set up the settings and convergence following the
service manual instructions. Prior to this, I have done so many
projector CRT swaps with no problems till now.
Upset and lost, help! UGH!
(1) This begun with original compliant for discolored spot that was
traced to spotty bad blue CRT. That spot was not the beam burn in the
center, it is in one of quadart and appox 2" irregular spot.
Cheers, Wizard
