    Im not sure where any of the fuses are.  Im looking to replace mine as well in the same model but cannot find anything that resembles what a fuse looks like.  Above and just behind the big black power supply box (im assuming is a small greeb elevated circuit board that says, [FOR CONTINUE PROTECTION AGAINST FIRE, REPLACE ONLY WTH SAME TYPE SAME RATING FUSE, REFER TO SERVICE PERSONNEL]  However, it doesnt look anything liek a fuse.  Underneath it has long thin silver shats which are sodered in from above and sodered in below to what appears to be copper wiring entering the power unit that are encased in a long white plastic piece.  To the left there is some sort of plastic clip that looks removable but the rest of the circuit would be destroyed if i tried to pry it off (not that i even could).  Any idea if I am even looking in the right place?

    i finally found a fuse underneath the power supply.  it says 5A 125V and looks burned.  Im going to radioshack to try and replace it.

Are these the speaker output fuses...if yes, they should be on back panel. if no, then are you also looking for board mounted fuses on the pc board?

I have a SONY str-de715 receiver and the display does not work. I've tried to increase the brightness and replaced the fuses. Do you have any other DIY suggestions that would be helpful?

Does the rest of the receiver work? Do you get audio output? If not, it could be the main power transformer. There is a thermal fuse buried in the core that if this opens, it will cause the unit to not power up completely.

It's very likely it is a fuse - does it work with any other speakers or headphones? Is there any reset on the back of the receiver? If not, unplug it, remove the cover and check the fuse(s).

Rate if this helps :)

Sony STR DB-930 Receiver jumping into protector mode

I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.
