Sony
KV27EXR25

          Ran into an odd problem: This set seems to be attempting to start, 
the HV pulses repeatadly but the set never fires up. the STRS6301 has been 
replaced, and connections touched up on the power sypply, Vert IC, HDT,.... 
The frequency of the sound the pulse makes sounds high although the 200v 
supply only makes it to ~115v during a pulse. HV is present at the anode.
