    I've got a Sony surround sound reciever on my bench, model# STR-DE505.
    A question for any familiar with these units.
    When I power it on I get a normal display for about 5 seconds then it
    flashes "protect" on the lcd display.
    Anyone tell me what most commonly causes this?
  2. A blown amp channel, or a bad driver IC.

    Solder up EVERY suspicious connection, then go with marks suggestions
    if it still does not work. For whatever reasons, some sonys seems to run
    way hot at eat up the solder connections faster than others.

    Many thanks. I'll start with those two.
  5. Sent the service manual PDF via e-mail - let me know if you don't get it.
    It's about a 6.6 meg file.
