Unit shut off. Why doesn't it turn back on?


Unswitched power has nothing to do with the power supply of the receiver. Look for blown fuses or a failed component on the power supply.

I have a pioneer DTS 96/24 multi-channel SX316 that just stopped working. Is there a fuse to try and replace? If so, where.


Remove the top cover and follow the mains cable into the unit. Any fuses should turn up near that. Make certain the power cord is out!

Teac ls-l800 not working , think blown fuse


1 AT fuse is a 1 amp fuse.

Fuses tend to blow when there's an overload, mostly caused by a faulty semi-conductor perhaps on the main power amp board.

Brand new used 12 times-would not turn back on pulled cover and internal fuse was blown. shutoff procedure using on/off switch only. accessible from back fuse holder should have been used for cases...


if you're blowing fuses, there is a reason. the most prevalent reason for this is shorted speakers, while the final amp is supposed to be protected by fused speakers, many times they don't work fast enough to protect the amp. If this unit is brand new like you say, put the old fuse (blown one) back in and close the unit up, hopefully you haven't destroyed the tab that shows the case had been opened, this unit should be under warranty, take it back or send it back (with authorization) to where you bought it, don't tell them you opened up the case or you will void warranty. good luck

Happy new year! my problem is that the stereo turn on but no sound. my stereo receiver is a fisher studio standard AV STEREO RECEIVER. RS-616


if its a new purchase with a warranty, then take it to them first to prevent any loss of coverage, and if not open it up and check for a round cylinder glass fuse, or white ceramic fuse, possibly might have blown it.
good luck!

I have hooked by two bose 161 speakers using 14 gauge speaker wire (about 8 feet) to sony str-dg720. But I get absolutely no sound from the speakers. I have hooked the speakers to port A set of input...


You gots ta isolate the problem.  Disconnect the speakers and hook them up to a stereo you know that works.  If you don't hear sound coming out of the speakers, then you know the speakers are fu.k.d up, so you need to look on the speakers to see if there is a fuse that is blown that needs to be replaced.  If you got sound coming through, then disconnect them and hook them back to the original stereo making sure you got a good connection and all the wires are in good and tight.  Then turn your stereo on and go through the various channels like Tuner, Tape Deck, Aux, and DVD to see if you get any sound.  Also turn the volume knob up. If you don't get any sound after all this, you know there is something wrong with the stereo your using.

Only makes a loud popping noise now


if it is still in warranty take to get fixed if not pull the case off and check the fuses if ones blown go buy a new one the correct size is written on them, if no fuses are blown then its worse, if you have friends who know about electronics  get them to look at it otherwise take it to a repair shop

Blown something? No amplification?


If you hear a faint sound I doubt if a fuse is blown?? never Know though. You have to have and know how to use a DVM or muti-meter to trouble shoot solid state electronics, as well as know how to solder and check transistors and other electronic parts. There wouldnt be one particular thing that could cause your problem. There could be a several things wrong as transistors and ICs tend to snowball and short out or open up with power surges. If you want , first get a schematic, but if you dont know how to read one stop right here and save your money and upgrade to a shiney new stereo system.. Good Luck
