Tried to hook up turntable to Amp and will not produce any sound. What am I doing wrong?

You are doing nothing wrong at all. It's just that as you say it has no phono input. Which means the sockets you have will NOT amplify the signal. So you need to buy a magnetic cartridge pre-amp and once connected to the aux the weak signal will be at the normal level.

To find out what the problem is try this, swap over the right and left leads from the deck to the amp. If the problem stays on the left channel there's something wrong with pre-amp in your amp. If it goes to the other channel (right dead) it's the deck. Next remove the wires to the cartridge to the deck with the fault. Make a note of how they fit on the cartridge before you do. With the amp connected to the deck and on. Touch (one at a time) each of the four wires with your finger. Two of them will probably produce no sound. But from one wire you should hear a buzz on the left channel and from another wire a buzz on the Right channel. If you get a Buzz on the left speaker then all the connects are good and the cartridge has gone. If you don't get a buzz, then there is something wrong with the left cable connector between the deck and amp.

Switch the turntable to Line unless you're using a Phono Preamp.

The output from any regular turntable is far too low for most amplifiers to handle. You need to either run the output through a pre-amplifier first to bring the signal up to line output levels suitable for most recording devices and amplifiers or run it into an integrated amplifier which includes the pre-amp stage.

If your Bose receiver specifically includes a turntable input then it has a pre-amp built in, but as so few folks use turntables any more very few devices have the correct input. Pre-amps are still easy to obtain and can be very cheap, but cheap ones produce a noisy and unpleasant output which is magnified by the amplifier. If ever there's a choice to be made, spend the money on the pre-amp and go budget on the main amp.

I hope that I've saved you wasting money on something you didn't need. Please take a moment to rate my free answer.

you turtable will need a pre amp especially if you have a magnetic pickup cartridge

Just look around the web for a "Magnetic Cartridge Preamp".
You plug your turntable into this and the preamp in an aux socket of Surround Amp and the sound will be the same level as the other devices.

Have you though of using a pre-amp? You'll probably need to go turntable --> pre-amp --> soundcard input to get acceptable sound

Let's figure out which hardware is failing. Connect the phono preamp to the CD or tuner input to see if it works there. It should. If it does, your receiver is at fault. Did the front panel controls get damaged?

How did the turntable fare in this accident? As a basic test of its ability to produce sound, hook it directly to the CD input and raise the volume slowly while playing an LP. If it's alive you'll hear a very weak, tinny sound, but I assume you know that or you wouldn't have a phono preamp in the first place and would probably be asking why the TT sounds so poor. :-)

Didi you try to change the middle. that was what was wrong with mine

It definitely has to go through a preamp (a PHONO preamp that is...) something like this: http://www.phonopreamps.com/tc400pp.html
