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.

SOURCE: High Def input search

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?

SOURCE: screen goes bright after 1 hour of use

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. ;-) )

SOURCE: No DVi input, then computer goes to sleep

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:

  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

generally that sign means that there is no signal from the transmitter of the tv company

Hello
Check all the signal cables at the backside of your Vizio for firmness. If there is any loose or bad cable connection, especialy with HDMI; will poise this problem. Check the input selection also. If improper input selection is done, there will be no signal logo will fly around.If you have selected TV instead of HDMI, when HDMI is connected and you want to see the programme, is an example of improper signal selection. Check these. OK.

Analog Audio Out signal has very high distortion. Signal wanes in and out, wanders from one channel to another, and develops high static. This happens when Audio Out is configured for Fixed Output. When...

The problem is more likely to be with the wireless headphone set rather than the TV. It makes no sense that the signal changes channels. The only difference betweent he fixed and variable output is whether or not the volume changes the output signal amplitude. The channel selection process is not handled there. The distortion is likely due to the input of the wireless being overdriven. If available, turn down the input gain on the wireless and try again. Please update this with the results.

Thanks,
Dan

No signal

You have changed the input to a selection that does not have a signal. Look at where the cable goes into the TV, this should show the name of that input, then change input back to that exact one via your remote.
