Question about Audio & Video Receivers

1 Answer

I have a older sony STR-DB830 receiver that keeps blowing two fuses labled f801 and f802. They are 125v 8amp. They pop the instant you turn the power on. Something is shorted, but I can't find it. Is this worth fixing? I have done some reading about this unit and it is suppose to be one of the better ones built.

Hello, i believe that your problem is in the audio output ckt, check all the transistor you have one bad channel (shorted transistors). with a soldering iron disconnect them and check them with a meter.


good luck

I hooked up more than one set of speaker wires in on set of terminals and blew the 2 8amp fuses inside. i replaced them ,but they blow right away when i turn the system on.


Hi Robert,
You've probably managed to fuse two wires together or one wire onto the casing. You need to find and rectify this before proceeding further.

Hi I have a str-dh520 reciever that has a 8 amp 125 volt fuse that blew and I could only find a 8amp 250 volt fuse and when I installed it it blew right away. What do I do now? Dose it have to be a 125...


No! the fuse you replaced was fine, the power transformer may be shorted, or the audio ouput semiconductors are shorted, check the speaker wires for shorts, if okay! I recommend a pro with a estimate.

CAN I CONNECT MY DB830 TO MY LAPTOP? I HAVE THE RECIEVER AND ALL THE SPEAKERS OF IT BUT I DONT KNOW IF I CAN CONNECT IT TO MY LAPTOP


You can use a cable with a 1/8-inch mini stereo plug on one end and two RCA plugs on the other. Radio Shack sells one so you can see what it looks like. Plug the mini-stereo end in to the laptop's headphone jack and plug the RCA end into an open input on the Sony receiver and you'll be good to go. You'll just need to juggle the two volume settings (laptop volume and receiver) to get the best sound.

I have to replace 2 fuses 8Amp 125volts from a sony reciever, but I can't find it to buy , do you know any site to order on line or if I could use 8Amp 250volts?


fuses have different sizes even though they have the same rating's, the best remedy to do is, do you any stranded wire, cut one piece out of the whole strand and solder it on the fuse housing that will do the trick.

Blows main fuse when power is turned on


Shorted power supply/module is most likely problem.

Sony str-de845 Powers up, relay clicks, fuses BLOW!


This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

Stuck protector mode


find out why the fuse blew in the first place.the protector is just PROTECTING the main circuits of the receiver.the receiver turns on just to confirm the power circuit is OK.
have it checked by an electronic engineer.
