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!

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.

Strange noises can come from your amplifier or the sub itself. The most likely cause of the strange noise is the speaker just before it dies! If you have been using the sub-woofer at high volume levels then you probably have damaged it. Try testing the sub-woofer using a multimeter(on ohms setting) it should give you a reading from 8 to 4 ohms. Sometimes they may give readings as low as 1 ohm. When testing the speaker/sub you should hear a soft scratchy, thumping or clicking sound. This indicates that the speaker may still be working. If you don't have a multimeter try a 1.5 volt battery (say a AA), DONT USE HIGHER VOLTAGE BATTERIES they may damage the speaker! You will hear a clicking, scratching etc sound from the speaker which may indicate that it is still OK. If the speaker seems OK the problem may be in the amplifier, which I suggest you bring to a professional repairer. When buying speakers and amplifiers make sure the power handling of the speaker is equal to or greater than the amplifier output power. This should stop speakers from getting damaged. Make sure the speaker and amplifier specifications are rated in the same manner ie RMS PMPO Peak. A 100 Watt PMPO speaker will not survive the output of a 100Watt RMS amplifier!

Make sure all your connections are tight and you have power to your speakers...Then go Start>Control Panel>Sound and Hardware>Sound, after you are in here make sure that your speakers are selected as default device.

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.

Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!

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.
