MY HP TV CHANGES SIGNAL INPUT BY ITSELF. YOU CAN SEE THE SELECTION TAKE OVER THE SCREEN ABD IT SCROOLS UP AND DOWN INTIL IT LANDS AND THE READS NO SIGNAL. I HAVE TO MANUALLY WITH THE REMOTE MOVE THE SELECTION BACK DOWN TO CABLE/THEN THE PICTURE AND CHANNLE I WAS WATHCING COMES BACK ON. IT ACTUALLY FIGHTS ME WHEN IT ACTS UP WHEN I USE THE REMOTE TO TRY TO STOP IT. IT WORKS FOR A WHILE. THE GOES CRAZY AGAIN. NO RYME OR REASON TO IT.
Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). 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. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

It sounds like you arent using the correct ports for a HD tv or arent using a HD digital player or HD cable. Still having problem let me know but thats what it looks like to me. Do you have anything plugged into these ports from a HD device? DVD,Digital Recorder, etc?

I have the same problem when switching component inputs. I also had a problem with the backlight going off after 10secs-5mins. Which is still being resolved.
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. ;-) )

Hi publicworker,
I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.
How to do that:
Maybe some changings/modification will help you too.
