I don't recognise your particular set, but this kind of problem can be
caused by a C-E short in the transistor which switches the B+ supply
to the line stage. What is happening is that the uP is unable to
switch off power to the line stage before going to sleep. When
replacing this transistor, check your B+ supply, and replace any small
electros on the primary side of the SMPS.
