Picture squeezed in then died
Hello Everyone at Badcaps,
I'm NormanSaxon86 brand New Badcaps member to this forum I really enjoy educating and sharing information concerning computers and electronics. Retract to the reason for this post my problem with the old Emerson CRT Model No. EN-710 It is described as the "Picture squeezed and died effect" What is described below sounds like symptoms of the incident.
Here is the Quote that pertains to my problem:
Picture squeezed in then died
You were happily playing 'Doom' when the sides of the picture squeezed in two inches or so when the entire monitor went dead - has remained like this since. There is no activity at all from the tube. Has it died? How much time, effort, and expense to fix?
No, it's not dead, at least it certainly is not the picture tube.
You probably shot the monitor instead of the bad guys!
Is there any indication of light on the screen? Any indication of the horizontal deflection running at all as evidenced by static on the screen?
In any case, there is a problem in the horizontal deflection and you probably have no high voltage as well assuming no light on the screen.
The fact that it squeezed in first indicates that a partial short or other fault may have developed in the horizontal deflection circuits - possibly the deflection yoke or flyback transformer. It could also have been a bad connection letting loose. Once it failed completely, the horizontal output transistor may have bought the farm or blown a fuse.
I heard of and read about on the link below.

While using the computer for a duration of 15 minutes more or less depending on the temp. the screen squeezed in horizontally a few times and then turns off to a black screen I notice the green led power light turns orange. The monitor feels warm, "heat sensitive". After about 15 minutes I can turn the monitor back on and it is fine for a while till it happens again.
I read that if I turn down my monitor setting it might help. I changed my monitor display settings so it might put less stress on the components, but I hope to fix the problem with the help of all you get people on Badcaps and share the solved problem for others like me. So now I have my brightness just adequate to see all the colors and the resolution display set to 1024 by 768. I am use to a brighter and higher resolution.
Did I burn out the HOT Horizontal Output Transistor or a Capacitor? I am a computer tech and spend sometime on monitors and educated enough to look for burns or the busted caps and I am learning to use a multi-meter.
Kinds Regards

A gassy tube will have very obvious symptoms and they can't be fixed like that... regular sillicone will outgas --- unless you meant using something like Vacseal which is designed for this application.
