Would any fellow tech's have any suggestions on how to isolate a 
shutdown on a Zenith IQB50M92W. I've gone thru the flow charts of Zenith 
and Hitachi,like disconnecting the E994 fuse and Q913 to ascertain were 
the problem is. Which leads to the 23 other causes of shutdown. My 
question is do I one by one check these B+'s in or out of circuit and 
fire up set for each one. Or is part replacement the only way. I hope 
someone can shine some light on this. Every time I send a Horiz/Power 
supply it comes back in worse shape or almost always the convergence 
would have to be completly gone over. Any help would be appreciated.

                                           Thanks  Bill
