My LC-70SQ15U TV was working fine, I changed the Audio option from "By Aquos Audio SP" to "By Aquos SP" a couple of times and now the "By Aquos Audio SP" is grayed out and I can't select it.

kitconnolly,

I too went through this problem.

Step 1 - Plug in your "composite" cables and the HDMI cable to the PS3. Obviously, the "composite" cable are the ones that came with the system. You need to start with them as the default connector.

Step 2 - After connecting the "composite" cable and the HDMI cable to the PS3, connect the other ends to your TV.

Step 3 - Power on your PS3

Step 4 - Select display settings-->video output settings

Step 5 - Change from the current video cables to HDMI. (Your tv has different inputs. When you switch to HDMI in the PS3, you will have to switch your TV to the HDMI input that it is connected to, to get a picture)

Step 6 - Be quick, the PS3 will display a "test" for 30 seconds. You need to switch your tv to the correct HDMI input and press "X" on your controller to accept the change.

Let me know how this works for you.

First off a little tip that manufacturers don't tell you is that you HAVE to TURN OFF the POWER to ANY UNITS that you are Connecting to via HDMI!!!!!!! If not you can short out the Inputs!!!!!!!! HDMI is usually Automatic, But sometimes you need to go into the Menus on all Devices to the HDMI section and write down their settings and compare them. Any definition that you are not sure of check the Manual or Google it! Match all the Settings (there won't be Much!) Hopefully the Inputs were not Damaged it only takes one time to short it out and then the Repairman makes a few bucks! Good Luck!

Your PS3 set itself above the max resolution your LC-C3237U. Most likely the PS3 is doing 1080P, but the highest the Sharp can do is 1080i. So do this:

1. Connect PS3 to TV (you can use the current cable or analog cable)
2. Turn on TV and set input to port PS3 is on.
3. Make sure PS3 is connected via correct cable.
4. Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.
