My monitor came up with a corner blue screen and inside it said NO composite input signal. I cannot delete it or minimize it. What does the message mean and how do I get rid of it

Your monitor has some of the following inputs:
* VGA
* HDMI
* composite
* component
* coax
You need to "tell" the monitor which of the above "input" channels that the monitor should "listen" to.

Those jacks you are plugging into on the HDTV are not composite inputs. They are component. The reason the color is not right is, you have to have a Red, Green and Blue connection.

The black and white picture from the 1 cable is because you are using a composite signal into a component green.

Big difference between a composite and a component signal. I hope this helps.

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Not sure this will help but it sounds like you might have PIP (picture in Picture ) turned on

The message you're seeing is part of your monitor's ROM programming. It is its response to an input signal that it doesn't recognize. If someone makes a composite to vga adapter cable, it's because they can sell it, not because it works. While both composite and vga are analog signals, they are not at all the same format. The signal gets to the monitor via the vga connector, but it's still a composite signal. Your monitor is all wtf about it. You can make HDMI to DVI cables, but that's because they carry the same digital signal. There is basically no way to connect a ps2 to a pc monitor that doesn't have composite or component input, unless you spend extra money. That can be on either a signal conversion box, which cost at least $50 and might not work so good, or a capture or tuner card for your pc that can capture the signal and relay it to the monitor as VGA or DVI signal. Either method basically converts the composite/component to vga or digital. There is such thing as a ps2 vga cable, but it doesn't work under the normal ps2 operating system, only under ps2 linux. It's hard to find, too. No point looking for one cause you'd only get to play homebrew games of which there aren't many.

That situation clearly indicates that no signal is coming to the set in its present setting. Have you checked to make sure that the tv's input is set on the right input setting. Mine always defaults to "Antenna" which drives me nuts cause I get that big blue screen with "no signal". It seems to do that at the slightest provocation, too. After 5 years, I still have to think twice before checking it. If that is not it, make sure that the cables are plugged in. If that doesn't fix it try another type of input such as HDMI or S video, composite, etc - one that you are not using. Don't forget to switch the input to it. Good luck!

If you have the same problem with both monitors, it sounds like a display card setting or problem.
The chances of you having the same problem with different units is 1- 50.
Try the monitors on a different PC and get back to me.

How do you have your DVD player hooked up to your TV(i.e. composite, s-video, component)? Some DVD payers and TVs have menus to switch inputs and if you somehow switched off the input your players are connected to, you'll get a "no signal" message.  First try hitting the input button on your TV or the Input/connection option in your TV's menu.  If that doesn't work try hooking up the DVD player(s) with the composite Cable(yellow), the component(red,green,blue) and S-Video(black/round) at the same time. If you scroll through your TV's inputs you should get a picture on one of these connections and the TV should display which one. The display will usually be in the corner of the screen.

Try the following:
Right after power on, tap the F8 key to see if you can get a short menu to come up.
If it does, select "Safe Mode."
If your screen looks different, it may be just the driver for the display card or monitor is trashed (Windows like doing that, keeps us challenged).
- Open Control Panel, then System, then Hardware, finally Device Manager.
- Locate Display adaptors, open and delete the adaptor listed (all, if more than one.)     - Locate Monitors, open, delete any listing there.
Reboot.
Windows should 'find' two 'new' devices and install the drivers for them.
The display may still be different if you had other than the default settings.
Go then to the Display folder of the Control Panel, click on 'Settings' and experiment. Depending on your Windows version, if you choose something dumb so it makes the screen unreadable, ignore it and Win will ask if you want to keep it and give you some time to acknowledge that you like it. When you don't, it will just go back to the pre-tinkering settings.       

push the PIP button until it says off
