This set uses 5 shutdown circuits and the HV is monitored at U1001 at 
pin #22. It should be about 1.5volts. You can monitor this to see if 
thats the shutdown reason. Also the 26volt line thats scan derived is a 
common problem. It feeds the audio output and could be your trouble 
site. I've also found the small disc caps in the SMPS section had one 
side with poor solder. But more common on the projo's.
Just my 2 cents.
