Happy New Year everyone,

A friend brought over a SONY DA5000ES surround receiver where the
owner had shorted speaker leads and blown a channel. He (my friend,
not the owner)had replaced the 4 output devices in the channel
(Q1671,1681, and 2 others that I can't see with the unit assembled.)
sourcing the output transistors from Sony.

The amp now powers up with a displayed message of "Check Code 11" The
topology of the receiver is totally unknown to me, and of course he
does not have a schematic diagram or service manual.

Any ideas?

Many thanks,

Hi Tim,

I found this on a Google search:
http://www.agoraquest.com/viewtopic.php?topic=31378&forum=51


"Here is the description of 11/protector in the Operating Instructions
(p60):


11/PROTECTOR



Irregular current is output from the speakers. Turn

off the receiver, check the speaker connection and

turn on the power again."



I would not power up that unit or most any unit with new parts unless it was
in series with a current limiting light bulb.


Happy New Year to you too.
