My computer screen got unplugged

Chances are the video cable has come loose. You will need to locate where that has happened and figure out if you need to securely plug it back in, replace a cable, etc. You may find it handy to have a flashlight, if you can't fully get behind your computer, etc.

Normally, there are two cables from the monitor ("screen") to the computer. One is power, which you likely know what that looks like (a regular power plug, going to the wall) and the other will be for the video from the monitor to the computer.

Modern computers typically have color coded ends on the cables with color coding on where they plug on to the back of the computer, etc. This is especially true if you purchased the monitor as a set with the computer.

Typically power cables are black.

Follow each cable from the monitor to it's respective location. Follow power cable from monitor to wall or where you have it plugged in.

Video cables can be in five different styles typically (oldest to newest):
(VGA: blue, DVI: white, HDMI: black, Display Port: black, Mini-Display Port: black)

Follow the second cable, the video cable, from the monitor to where it should plug in on the back of the computer.

Make sure each is securely plugged in to where it needs to go and is hand tight snug, but not too tightly screwed on at each end.

My dell 4700 won't come out of sleep mode, i've rebooted and changed the internal battery but still no luck

Get some canned air - 2 cans
unplug the monitor and computer.
Use canned air to blow out all the vent holes of the monitor.
Leave it unplugged for about 1 day.
Open the computer case. Use the canned air to blow out the computer. pay special attention to fans and the power supply - actuall blow the air through the power supply vents on both sides.
If you have an add on video card (not on the motherboard), remove the screw at the back of the case, and remove the video card. Reinsert the card and make sure it is tight. replace the screw.
After the day is up plug the monitor back in and use the buttons on the front to enter the monitor menu. Choose to reset or factory settings.
Hook it back up to the computer and boot the computer.
If the problem still occurs try the monitor on another computer or laptop.
If the problem goes away by hooking it up elsewhere - replace the video card.If you are not sure what type to purchase just post back model and serial of the computer.
If the problem is still there after hooking the monitor up elsewhere,
Try changing the video cable or seek rpelacement through warranty or purchase a new one. Check for best prices.

Any doubts you can get the help of a technician through

Monitor has bluish tint

You should check to make sure the cable is tight at both ends (back of the computer and back of the screen). If it is, and you've already replaced the monitor, it's probably the video card in the computer. If your computer is still on warranty, I would suggest contacting the manufacturer or the retailer where you purchased it. If not, it looks like you'll need a "PCI-Express x-16" graphics card, which you should have professionally installed.

The power light keeps flashing orange when trying to switch my pc on i only get an orange flashing light no other life in it whatsoever........

It means to say that it is not getting enough power on the computer, check the power cable at the back of the tower and make sure the power cable is connected tightly. You can try taking it out and then putting it back in again to make sure it is connected firmly.

Monitor goes into Sleep Mode immediatly upon turning on computer

Ok. I think "sleep mode" means that your monitor might not have a tight connection. Tighten all connections. Also, push the power button on your tower. When you gegt back, go to screensaver- power settings- and from there you can adjust.

Monitor says no signal

this could be a multitude of things. Firstly, check the connections from your computer to your monitor, unplug them and plug them back in, make sure the thumb screws that connect your monitor to your computer and nice and tight but dont use a tool to tighten them, hand tight is good enough.
If that doesnt work, then check that your graphics car hasnt been unseated from its slot, TURN OFF THE POWER to your pc, open the case and look at the graphics card inside. Push it straight back against the slot and that might help.Try connecting the monitor to another computer, although I dont think its a monitor problem. or borrow a monitor from another computer and try it. If that doesnt help then you can try a different graphics card, if you dont have one they are readily available from most major electorincs stores, or even most supermarkets with an electronics dept. Now if you do all this and it doesnt fix it then you will need to find a tech to have a look at it, Like I said at the beggining it could be a multitude of sins, a hardware error stopping the computer from booting and that requires a little technical knowledge

Before we moved to a new house my samsung syncmaster 710v monitor was working fine but when I reconnected monitor to the cpu, no picture appears but green power led flashes and when i disconnect the...

First make sure all cables are tight and secured, and try pressing the Auto Button on your Syncmaster? It's for auto configuration.

If problem persist and if possible can you try using another known normal monitor/LCD? Also try your monitor using another cpu or laptop.
