[TechAssist] Re: Sanyo DS27910

Brock,
That zener looks like a silicon diode...near the HOT...Check it in case you get 
the thing fired up...
From Tech Repair CD:
SANYO\AVM3259\DEAD* F601 BLOWN\\\\Q601(C4423)*Q604(C3807)*D612(TLP621-1-BL)*
D601*D602*D603*D604(1S1887)\\\\\\\\

Sanyo \DS31590\DEAD-lightning\\\\Repaired primary side*Q601*Q604*Q605 all 
shorted-also had caps C609 blown
apart and C626 bulged like a baloon\Replaced IC601even though it checked 
ok.\Found Q695  leaking.   Q695
is 2SA608F.   Replaced it with a TCG290A\\\\\\

Good luck.

Thanks Jeff:
    the fuse on this set doesn't blow,, well, after replacing the shorted
transistors it stays in tact, I'll check the zener if I can find it,  I get
a start up surge when I plug in the set,  but no click or any other
function, almost acts like eprom or missing input information somewhere
except that my standby voltages are missing,  transformer is ok,  I hate to
short the relay but need some voltages to go much farther without a print.
