SPEAKERS IHAVE NO SOUND FROM SPEAKERS WHICH I THINK ARE BUILT IN TO THE MONITOR MAG INNOVISION LT765S 17" LCD SCREEN PLEASE HELP! BETTY

Yes the Mag 900P has built in speakers. The audio lead for them is attached to the blue VGA connector and has a green tipped plug like a set of desktop speakers.

Change the screen resolution refresh rate,to desired one.

Sometimes the power adapters on flat screens face the floor. So, if you look under the screen under the stand, you will likely see the plug.

I have had similar problems with my Mag LCD monitor. I recently dicovered that the problem was with the adapter and not the monitor. Try replacing the power adapter.

I have the LT765s and it has speakers. Don't know about the 765.

If it supports sound there will be two inputs, line in and line out, on the back. The "line in" jack goes to your sound card output.

If your monitor supports sound (might have to be the LT765s product?), there will be two inputs on the back (to the right when looking at it from the back). One's labeled "Line in." This is where you'd plug the audio cable from your sound card.

make sure windows volume control is up.
its the speaker next to the time and date ,on tool bar ,bottom left normally.

play a song or video or such.
then check the cable in back of monitor it has a plug/connector that looks like a headphone jack /plug
follow it to the back of computer its color coded.
be certain the speakers have power if needed they will plug into monitor dc jack if the speakers are removable.
and check the vol control on the speakers.

Check and make sure that the speakers and any power supply (UPS) are not placed very close to the monitor.

monitor is looking for the video signals--move mouse and try power on

you will have a mains lead with an electric kettle type connection on one end which plugs into the rear of the screen and another similar lead for the pc.

the video lead from the screen will plug into a small dovetailed shaped connector coloured blue on the rear of the computer ( it can only fit one way round , as its broader on one side than the other )

the speaker leads will probably be small jack plugs one for left and one for right, and they plug into the rear of the computer, audio out / left / right.
