I have pink color horizontal lines on my LG LCD monitor screen,How do i solve it?

You can fix you have to follow this instruction

1-Reset the TV by unplugging its power cord for 30 seconds and plugging it back in. This is an essential troubleshooting tool as a simple reset often will resolve the great majority of technical issues experienced by any kind of TV. Power the TV on after plugging it back in and check the picture for any improvement.

2-Unscrew the coaxial cable that attaches your wall cable outlet to either the coaxial cable input on the plasma TV or to any digital cable converters you may use at home. Check the copper needle in the middle of the cable for any bending or damage and screw the cable back on the coaxial input. Again, check the picture for any improvements.

3-Secure the audio/video connection cables that attach the source device you are trying to watch to the plasma TV. This is a particularly important step if you use component cables. Component cables separate a video signal into different colors, so a damaged or loose component cable can lead to noticeable discoloration on the screen. Once the cables are secure, both in the source device and the plasma TV, check the picture again to see if this may have resolved the issue.

4-Scan your channel lineup and check the other TVs in your home to determine the scope of the problem. If you see the discoloration only on one or a few channels, and the same channels are discolored on the other TVs in your home, you may be part of a cable service outage and you will need to report the issue to your cable provider. If all the channels on the one TV have the same discoloration, and the other TVs in the home look normal, the plasma TV likely will need to be serviced for a problem with its picture components.

hope that it helped

What you need is a device called a multi-switch. Here's a page which details some of the switches available with different satellite setups. You would hook up your sat recievers, your TV and your recorder up to the multiswitch:

No picture

It is uncertain to me that if the monitor is not turning on, with a power light visible or that it comes on and but no picture. My question to you is whch is it? If the power light is on the other question is do you hear sound when you try to play a movie or whatever you use it for? If you have sound that shows me that the monitor is on and working less picture. If this is the case it could mean several things. Some of which dont have anything to do with the monitor but with your settings. Are you using a laptop to hook up to it. If so are you using an HDMI cable connection? The monitor needs to be set to the hdmi input, your laptop might need to be switched to play on the monitor rather than your computer screen by pressing the proper F key. If all of this is correct then I suspect if you have an lcd screen monitor the backlight might have to be replaced. If plasma the plasma light. If it does not have any sound and the settings mentioned above are correct then you have a power supply failure. It could be as simple as a fuse, but in the new electronics the fuse might not look like a fuse most are use to seeing. The glass kind. The new kind are only known to the trained eye. You know you might also make sure whatever you have plugged the unit into has power? surge protector etc. Whatever the case may be plug something else into the same socket just to make sure that works and you know you have power. I do not know your level of understanding so I try to cover it all.

My 43inch nec plasma, will not pick up an incoming signal. it switches on (blank screen), but after around 20 seconds, it goes to standby.

It's going into standby because it's not receiving anything on another end for a set period of time. Be sure to check certain aspects of the monitor if you are connecting it to a PC.
Check if the PC is on first. Obvious, but youd be surprised. Make sure both cables are connected firmly and securely. Also make sure you're using the right cables. If the monitor has multiple inputs, try toggling through them If it still doesn't work, check if the computer is outputting signal on another monitor.
Hope some of these tips help

No video output from my computer.

Are you using an ON-board graphics adapter or a separate VIDEO CARD? Some motherboards lets you set the video output to "DISABLE ONBOARD GRAPHICS" if you have installed a video card (BIOS). You may have plugged the monitor cable to the onboard D-sub connection instead of using the Video Card D-sub connector.

Normally a flashing green power light means the input it receives from the video output is too much. You may have set the resolution too high or the bit depth too high. Consult the monitor manual on the rates it can handle. To be safe, try starting the computer on safe mode just to check if it is indeed the problem. If it boots properly and you can see your desktop, then there's a chance that the setting was too much for the monitor to handle.

Hope this gives you an idea.
