Question about Sharp Televison & Video
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Warranty still alive?
Hope so; the problem could be an expensive one.
The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.
I would be talking to Sharp - this shouldn't happen in 6-7 months of use.

SOURCE: Loss Sync
According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective.
Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again).
It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box.
Hopefully, this will clear the problem if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

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.
