Possible blown fuse on Sony STR-DE725

Hello! Actually I have a Sony STR-DE725 which I love and have never had any problems with....till last night. I was rewiring a rear speaker with the power on and....yup, you guessed it. The unit made a funky sound and I lost all audio and I also lost all the LED details on the face of the unit. I was hoping to find and replace the fuse(s) as I suspect a unit such as this must have but could not locate it on the outside. I have some knowledge of electronics and the tools to make more than simple repairs. However, I don't want to make matters worse by going in blind. Could you point me in the right direction as to the location of the fuses that need to be replaced? I have moved a couple of times this year and I'm afraid i've lost the manual along the way. I would truly be most greatful for any information on troubleshooting this problem. Anyone out there with a solution? Thanks

Blown 2 8a 125v fuses, replaced them and blown them again. I used this stereo for 10 years without any problems Can this be fixed, I threw away the last one with the same problem. The tech said it was...


Yes it can be fixed you have a short in one of the output channels. Probably needs two transistors. If you keep putting fuses in it will need more. You are looking at $100 to $125 for the repair.

No Display, no sound- not working, showing dead. But input Power is ok. Picture tube filamment not getting power. model sony KV-2192M3


Hello
Check the input fuse first. If it is blown, there will be some short inside the power regulator circuit. Usually Sony sets uses STR regulated power supply. You can see this STR, and Ic, screwed onto a heatsink. Replace it with a same type and number. Before replacing the STR, check the diodes used in that section for damage, mainlu zener diodes. They might get shorted along the blowing of the STR. Check that section throughly before resoldering the new STR.
If any further assistance you needs, get me through Fixya. Ok.

I am thinking of buying a SONY STR DE725 (QS Series) AV receiver. I alreay have a set of home theater speakers with 5 x 80W 4 ohm and and active Sub-woofer (200W). I am wandering whether the receiver...


Yes, it will support a powered subwoofer.

If your existing speakers are from an all-in-one Home Theater in a Box and they have molded connectors you'll have to chop them off to make the ends bare wire and determine which is plus and which is minus on each. Loads of 4 ohms may present a problem at high volume levels.

Take the rated wattage of the sub and other speakers in an HTIB with a HUGE grain of salt. They plays numbers games with th low impedance and the allowable distortion levels to get the results they publish.

For all anyone knows, the speakers and their original electronics may have been designed to operate together to yield adequate performance (like Bose does). Breaking that pairing may give unpredictable results and risk of damage to the speakers or the new receiver.

Sony STR DE-445 unit powers up but no sound


Check the fuse, Sony is known for its random problems with sound. The one I have you must tap it on the side. Its a flicker switch inside.

I have a Sony STR DB930. Something happend and it


The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.

Sony "Protection" mode - STR-DE725


My sony used to do that to umm cant remember the model but yeh i could play it at low volume but as soon as i turned it up it would start clicking and telling me to turn of the power...

I resolved it by checking every cord connected to it, it turned out that because I connected two speaker cables together i didnt seal it properly and they were touching this was making it go into protetion mode.
