Jim it would seem to be hard to put in a service mode when it don't stay
on long.

No it is not worth much more time but since it belongs to me I will try
again.

The wabash flows from you area down to my area.

Sounds like you need a service remote to put the set into service mode
which defeats the protection circuits so you can troubleshoot the
problem, but is a 20 inch set worth spending a few bucks on a service
remote? Which way does the Wabash flow? Toward the Mississippi? Ok, go
ahead and dump it.

I am going to try this one more time before I throw it in the wabash
river. 
When I hit turn on I have a couple of seconds to take measurements. Then
I have to unplug it to turn it on again. By doing this several times I
found that the HOT has 90 vots on collector. Horiz. driver has 20.2. 

All voltages on the vert. IC are good. 
These voltages stay on for about 2 seconds. You can see a picture just
before it shuts off.
