Question about Audio Players & Recorders

HELP Hi I have a STR DE915 receiver and the word PROTECTION now flashes on the screen, this has happened before and it was fixed via a sequence of remote pushing by an old friend of mine, only I don't know it how to fix it and am unable to contact my friend. All I know is that the receiver has this feature should it heat up and to protect it from blowing this shows up.Could somebody please help me? Thank you.

If you unplug the unit from the wall plug for about 10 minutes and try it again and you still have this problem, then you probably are having a problem in the output circuits of the unit and will need to see a repair tech. If so, be sure to remove the power plug in the mean time. Good luck.

I have a SONY STR DE915 receiver home theater amp. After 14 years, it decides not to power up! Are there internal fuses? Can i replace the power supply myself?


There are internal fuses that you can check. This model was notoriously bad for amp problems. These amps would burn up a lot of components when they go out.

Hi i am a new member and i have a problem with my str-k840p it started to have a protect mode flashing and I can't hear the at all the tv or speakers. What could i do i check all my connection and they...


Hi,
Protect display indicates that receiver is in protection mode due to some serious problem in output amplifier section and most probably any output channel output chips got shorted out.
Protection mode turns On to avoid any further damage in receiver. If your Sony STR-K840P is under warranty then call numbers written on warranty documents to ask warranty cover and if unit is out of warranty then either Sony service center or local repair shop will help you to get it fixed, it is not user level repair.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

The word Protection blinking.


The protection should only come on if the unit has been overloaded. Try to unplug, wait and replug.

if your preferring to protect light your either, pushing to much power, or a wire could be touching along the line. Check all your wiring even the ones behind the receiver that could be your problem

Auto - protect message


there are two small transistors in side of the receiver, that are not working, if you are daring enough, go ahead and try to find out which ones they are, or find a repair tech that is willing to do it, as this requires surgical soldering skills to fix.
