[comp.sys.zenith] 1390 POWER SUPPLY

spike@wasp.eng.ufl.edu (Ken Gage) (10/29/90)

I was wondering if anybody knew exactly what component causes the failure of     the transistor "Q3401" on the power supply.
   
I have three power units that have failed in the same manner and we have no 
 access to any schematics.

  #NOTE: these are the 1390 enhanced.

thanks. Spike.
