i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):
1. lay the tv on the floor and take off the back panel. (i think 12 screws)
2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.
3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )
so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)
at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.
4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

That message is presented when a selected digital channel is too weak to decode. Let us hope that something was accidentally changed:
Is the channel legitimate?
Is the antenna/cable still connected (to the Digital input)?
Go into menu - setup - channel setup. Is the selection of either cable or air channels correct for your situation?
Use menu - setup - Antenna Setup-DIGITAL to examine the signal strength. Is there nothing at all, or is it just a question of strength?
Odds favor a change in channel setup that you would not have made intentionally, or a simple physical problem (input cable, etc.). Start from scratch, and check the settings and connections you originally made. Hopefully it will be simple and cheap!

This is basically a message for no signal on the tv, make sure the tv itself is on the correct input for the type of cable used. The inputs are labled by numbers on the back of the tv. The input can be changed by the button on the side panel of the tv.

Call up Sharp, if you are part of the AQUOS Advantage Program, you get FREE in home service along with the repairs for it.
They'll give you a case number, set you up with a technician and BAM!
I called on a Wednesday and got an appt for that Saturday for the technician to come to my house.
I doubted Sharp alot less after that.

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.
