It can be that your PC video resolution is set higher than 1024 x 768 @60Hz for the monitor to display correctly.
Try this per HP:
HP Business Monitors - What Do I Need to Do When the Message Sync out of Range Displays on the Monitor? ISSUE: What do I need to do when the message Sync out of Range displays on the monitor? When the video card signal exceeds the frequency allowed for the monitor, the following error message may occur: Sync out of Range SOLUTION: To avoid the message, lower the resolution or vertical frequency of the video card. Reboot the system and use the VGA mode to force the video card driver to lower its resolution. Follow these steps.

SOURCE: Input Signal Out of Range
I have an HP 1730 LCD monitor on a Compaq Presario S5100 desktop PC running Windows XP, up to date on patches as of 2009 Feb 25. For no apparent reason, the "input signal out of range" error message started appearing when the machine switches from boot mode (which looks OK) to regular windows mode. (My configuration does not HAVE a "safe mode" boot, by the way, so the usual advice doesn't apply.) Was the fault in the monitor, or the computer?
Step 1: see whether the computer is actually booting or not. Result: Over the home LAN, I was still able to access the shared directory on the suspect machine. This is good.
Step 2: swap the LCD monitor for an old Compaq MV720 CRT monitor. Result: the monitor does not like the input signal (essentially, the out-of-range error by another name), so the video signal IS faulty.
Step 3: reboot the PC with the analog monitor still attached. Result: the system boots up just fine, so there's something wrong with the way the PC boots with the LCD.
Step 4: swap video cables (without rebooting). Result: the LCD displays the working desktop, so the LCD display is still good, but there's still something wrong with the handshake between the LCD and the PC during boot. But we still don't know whether the LCD monitor is failing to produce the right Plug-and-Play sequence, as it used to, or the PC is no longer correctly interpreting the PnP sequence, so it's mis-configuring the video signal for the monitor.
Step 5: Back everything up, like you always should have been. (Always the last step, after a computer failure. ;-) )

SOURCE: problem with hpl1506 lcd
if your pc display resolution is set to 1024 x 768 and still having this problem... then your LCD control board is faulty. WHat you can do is try to hook up your pc to another monitor and try other resolution setting. If you still get the same error...then you will need to get someone to repair ur LCD...
