Would it be just the board with the HDMI it still works with the component input just not the HDMI

To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset.

i have had to replace the hdmi input board on these units to fix them.

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!
SOURCE: Problem connecting my PS3 to my Sharp Aquos LC-C3237U LCD TV
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.

Does the HDMI output on the PS3 have to be turned on first in its settings? Make sure the settings on the PS3 are at a minimum of 720p as if it is set to 480i the TV probably wont notice anything connected to HDMI.
