It could only need some soldering of the display itself. If you want to try it your self.
remove the top cover (you may need to remove the front panel also)

  1. inspect the twenty or so pins of the fl display tube especially the end ones (resolder if bad).
  2. if they all look good check for DC voltage on the end pins (20 to 30 volts)
be careful not to touch the transformer pins when unit is pluged in and the cover is off!

Hello my sony audio/video control center #STR DE335 is in PROTECT MODE.. and i cant listen to it..can u please tell me whats wrong?


PROTECT display indicates that receiver got serious problem in output amplifier section and protection mode is activated to avoid further damage.
Output amplifier section should be tested by qualified technician to find out and replace defective part(s) to solve this issue. Local repair shop will do this job as it is not user level repair.
Thanks.
