I have a STR-DE698 7.1ch receiver that started turning itself off
recently. I suspected heat as the cause, so I moved it out of the
enclosed cabinet and into an open one. I also set it on top of a
laptop cooler to dissipate any excess heat. The unit still turns
itself off after running for a half hour or so. I do not believe heat
is the cause, since it is cool to the touch when it shuts down.

Anyone have any ideas?

Thanks,
Dan

All the STR-DE series have a common problem with the ground screws on the
main CBA being too loose and not properly grounding the board. Use a Philips
screwdriver to tighten all of them real good, and see if the problem goes
away.

Thanks for the info. Where would the ground screws be located? I do
not have a schematic. Should I just open it up and tighten all the
phillips screws?

Thanks,
Dan

Yea, if I remember they are copper coated - several are on the perimiter of
the board, but some are centralized on the board.

I checked all of them.. None were loose, but I tightened them
anyway. The receiver still shuts off. No error message or
anything. Any other ideas?
