I've seen those too. However after many weeks of research, I discovered 
that if you plug them back in they will come back on though! *ROTFLMAO*
(I'm bored from the snowstorm, no customers, cabin fever, etc, - or is 
it showing?)

Just a thought, but I have seen TVs that when unplugged won't start again.
Check the caps in the power supply primary.

I had a call originally on this for convergence going out after 30-60
   

minutes. Replaced STK IC U19700 and
 

open R19233 (15K-3w). After replacing these, the set is dead...I double
   

checked every connector many times
 

and can not find the problem.

S/B voltages seem find(no print)..Best I can do from my notes is, pin 5 of
   

micro has 2.5v, press power,
 

goes to 0 v.
U14701 has B+, but 0v on either output. Replaced and still 0v..I
   

disconnected the output from circuit and
 

still 0v, replaced, same problem..
I measured these pins as I pressed power and the 5 volts for the output
   

comes up, but the 12v goes to a
 

couple volts, then to 0.
I've tried the troubleshooting guides, with no luck...or they don't apply
   

to this set.
 

I am still at a loss what could have happened from the time I ordered
   

these convergence parts and replaced
 

them..any ideas?
Thank you.
