Hi all,
In my years of swapping CRTs of any types I NEVER had this happen like
that, cracked projector CRTs face YES, have seen few caused by letting
coolant run out too low, CRACK! But this one is FULL of coolant and
tube self-destructed rather unique way.
The Blue CRT was initial tube we changed for discolored spot
complaint, prior to this swap TV was operating normally. After this,
couldn't do grey scale without poor picture and shutting down and unit
kept shutting down on brights. Helped if I turn down one of the
permeters in service mode, still shutting intermittently.
Changed other green and red CRTs got grey scale working but shutting
down persists. The TV simply cuts out and power blinks out and back
on trying come back then stayed on. Sometimes stays off. Can turn it
back on.
Our field manager we talked to for thomson says vertical problems and
I have not seen vertical collapse that could had broke this blue CRT.
I still don't buy that yet. Error codes were checked and it didn't
point to this area.
Drag that POS back and set it up to troubleshoot intermittent shut
downs displaying underscan pic of windows desktop via video input.
Turn around and getting stuff ready, turn around toward and see TV
dead. Found this broken CRT. GULP! Second blue CRT ordered and this
took record longest for order to come in. Was told that thomson had
to collect number of CRT and rebuild them because they were not making
new projector CRTs for these models.
Oh, I have to order string of yokes. Oh JOY Oh JOY! Edsel TV
strikes again; RCA in their infinite wisdom created 2 plug yokes
assembly all strung up in a row so you can't replace just one yoke out
of three. Oh joy!
Here's pics of this broken blue CRT. All pics are under 30K except
"two_piecesFLASH.JPG" is 45K

UP is front. Note spider cracks, one long across, and two small
diagontal cracks, on the side of CRT is a crack running towards neck.
