Re: Monitor "No Signal" RGB Box

Turn off your system, then turn it bacc' on.

I did this, It worked.
Restarting & All the other stuff doesn't work. I tried it all.

The easiest way is to just turn off your system, the electricity. The one that connects all the cords to your computer.
Sorry, if it's confusing. But hopefully that helped.

My monitor keeps giving me a no signal message after i turn on my computer

  1. make sure that the video cable is properly connected between the monitor and computer
  2. change the video cable
  3. do a monitor selftest
  • turn off the monitor
  • disconnect it from the power outlet
  • disconnect it from the computer
  • turn on the monitor without the video cable
if you see the monitor information (a box with RGB white colors, the monitor is working)

  • problem might be the cable, video input port of the monitor or the video output port of the computer

An Out of range box


If you are getting this message this means that you are connecting a device to the monitor and/or a connection that is putting out a signal that is not supported but the monitor. You may also need to look at the cable you are using. Example I have an XBOX 360 with the official VGA cable when I use it to connect to my monitor it works fine. However I have been testing cables to get a setup for my PS3 as I have not been able find an Official one from Sony. So when I connect my RBG to VGA cable to the end of my RGB XBOX cable then to my monitor I get an Out of Range message. So something with the cable is case a problem with the signal to not to be sent properly.

Note with monitors they have a safety feature that they would turn off if they got a signal they did not properly support and/or not read properly. This has always been there they just not got where they would show you a message. Plus with monitors getting bigger they have stopped supporting lower resolutions so you may see this issue more often when hooking up older devices. I my self still have a 15 and 17 inch on my work bench for toubleshooting.

Hope this helps clarify things. Feel free to reply back with what device you are having trouble with.

Why won't the HD channels come in on my lg flat screen monitor? We changed the cable box and everything. Any suggestions?

The first thing you need is the HD tuner. Since you stated that you changed the cable box I will assume that means it's HD ready.
So you have HD signal coming in to the cable box box by-way of a coaxial cable. Now you need to get that HD signal to the monitor. For this connection the standard coaxial cable normally used between the TV and cable box will not do the job. How many connection options you have depends entirely on the what is available on the monitor.
Normally there are three choices. Your monitor could have anyone of these, a combination of them or none if it's not HD ready.
They are Component cable, HDMI and DVI.
Component is a combination of three RCA type (red, blue, and green), connectors. Simply connect the "Component Out" from the cable box to the "Component In" on the monitor.
HDMI cable looks similar to a computer monitor cable but bigger. Same goes for this one. Connect the "HDMI Out" from the cable box to the "HDMI In" on the monitor.
An indirect connection can also be made if your monitor has a "DVI In" jack by using a cable that will allow you to come from the "Out" connection of either the HDMI or Component on the cable box to the "DVI In" on the monitor.
If you are unclear about anything or you have any other questions please just ask and I'll try and help out.

I work with 2x193W LCD Monitors together. One is working fine, the other is now giving me the "No signal" screen. I have checked connections and pins. Everything seems alright. What am I missing?

Open you video cards control panel and check the display settings. Check to see if it is set to duel view or single display. You can also open your display settings for your computer. Under the settings tab choose which monitor is showing no signal and make sure it has a check mark on the box that says extend my windows desktop onto this monitor.

RGB No Signal Message

First you need to check the cable at both ends, inside and out. Make sure it is plugged in, to the proper connector and that there aren't any bents pins. Now put this monitor on another computer, a laptop will do. Does it come on now? If so then your video card in your machine is bad. If still bad then the monitor has lost it's signal input. This will have to be repaired by a pro. I repair these all the time and it's not as expensive as you might think.
