Unresponsive.Dead.Fuses all OK.
Plug in and hear a very faint whine from the SMPS.
Testing found the following SMPS parts shorted:
Transistor Q606,(small case, A1271 on part).(2SA1271?)
Diode D615,, small black, Zener symbol on board: (on part:2.B, ZC, 33)
Diode D629, small glass.No# on part.
All shorted. Need parts ID on these, and possible pattern of known
damage from any histories on this symptom/model.
Possible lightning,considering our weather.
