Sony amplifier problem

I'd suggest you concentrate your search around the power output.

are you sure you have connected a sound source to the inputs correctly and turned on the sound source so it is playing into the sony?
If you have use the sony controls to turn up the volume and then select each input source one by one, do you then hear it?

Your Gamer 2 Amp turns on whenever an audio signal is present on the input. The amp can have trouble tuning on if the output of the source (computer sound card, etc.) has been turned down. This can happen easily if you use amplified speakers - if you turn the sound card's volume control down - and then increase the volume at the amplified speaker - the resulting sound is the same; even though the signal has been lowered. The problem is that the output from the sound card isn't sufficient to turn on the Gamer 2 Amp.

Try turning down the external speaker volume, then bump up the sound card volume. You'll probably need to adjust the other inputs individually (Wave, Mic, CD, etc) so that none is too loud or soft. Once the input values have been set, gradually increase the output of the sound card in the control panel application etc. while decreasing the volume on the amplified speaker to maintain a comfortable level. Eventually, you'll find the correct volume level on the sound card output that will wake up the Gamer 2 Amp.

If you're still having trouble, review the manual, here. I hope this helps & good luck!

Well...as you said...the unit powers up...so you don't have a "dead set".I don't know if the speaker can be disconnected from the unit.As a rule of thumb...it is very rare that both channels (left and right )fail at the same time...it is usually one channel while the other speaker still operates.This is what I want you to do...In a quiet room..get really close to the unit...Switch it on and listen for any sound from the speakers...get really close...you should hear a slight hum from the woofers and a high frequency "hiss" from the tweeters....If no sound is heard..switch the unit off..You should hear a "plip" sound...If not...switch it on again...you should hear a slight "bump" sound from the woofers...If you hear no sound from the speakers at all..there is a problem with the output stages of the amplifier section.If you do hear sounds fron the speakers,,Turn up the volume and watch for an increase visually on the display (such as ascending numbers).If there is no indication of a volume increase...The "mute" may be stuck on..Try switching it off and on...please let me know what happens after you do all the tests....Looking to hear from you......PEACE!!!
ok...

I would try using another speaker to see if you can get the sound back, this will help you narrow down the problem, you can also use the effect send to feed anothe amp to see if you get the sound OK.
It can be blown speaker or output stages,

Hello
Either your TVs speakers or its output IC may have damaged. To confirm it, just up the volume of your tV, and try to hear the sound if any. If it feels like dostorted or very low-hard to hear, the speakers must be suspected. If there is no sound signal at all, output IC should be damaged. To confirm whether the sound detecting section is Ok, just connect your TVs audio output sockets at the rear of your TV with an amplifier or so, and rise the amplifier voluem, to get sound through it. If you get sound in this way, make sure that the above daid two items. Fist check the speaker, by connecting an external speaker in place and listen to it. If it also doesn't get the result, surely the output IC of your TV has damaged, and should be replaced with same type and number. OK.

If you can't hear any sound from the headphone output, and by sound I mean a hum with the volume turned up, then the amp has either got a faulty internal power supply or the main amp has failed. Try looking inside to see if any fuse has blown. Also look around to see if you can see or smell anything has blown.

first turn the actual volume up on that channel on the reciver then make sure your speaker wires in the rear are using the same lenght each

Hi, Mark Here, see I can help.

The 1907 does not amplify your sound it will let you control the volume to some degree but not boost the incoming sound.

If you had amplified speakers b4 your sound card requires amplified speakers.

Best two options i can give is.

1. If it is a desktop you can install a amplified sound card. Hook to monitor speaker.
   
2. Unplug monitor speaker &use amplified speakers.

Just so you know laptops use internal amplified speakers. If you decide to install sound card make sure it is an amplified card.

Hope that fixed ya! know not the best news. Need more help comment back. Please Rate.
Good Luck!

Set your SAT receiver to full volume and use your Sony TV volume control as the master volume control. If you use an external surround sound amplifier do the same thing using the amplifiers volume control as the master volume control.

Consider that all source devices that have the ability to control their output volume will output what they call line level 0dB when the source device is set for maximum volume. If you set the source device to 1/4 volume your output to the amplifier may be around -25dB or lower. Introduce that low of an audio level to the amp and you will have to turn the amp up to half way or better causing the amp to amplify noise too.
