When i turn it on it shows ...NO SIGNAL VGA INPUT ... cant get it to do anything else

And then what happens? Does it continue of stop or boot or ? What is the connection from the computer to the monitor?

Disconnect all inputs. Unplug set from AC for 1minute plug back in and turn on set. Press menu and select input Antenna, cable,HDMI video etc. Connect source to that input.

Have you checked these?
1. Input settings in the TV,
2. Cycle the laptop output (laptop screen, external screen, both)

Because your laptop needs it's display setting changing so your second monitor is active.
While on your desktop, right click once and a box will appear, choose "properties" at the bottom.
There you will see another box, choose the "settings" tab at the top right and this will show your display options.
Right click on the number two box and "attach" it.
You may also have to change the size of the display to fit your tv.
Hope this helps

its because you failed to read the Samsung manual on your PC
go there and read, it has HOT key , all laptops have a hot key
Fn key that turns on the external display VGA jack.
on rear of this SAMSUNG.

SLEEP MEANS THE PC IS NOT SENDING THE HORZ AND VERTICAL, SYNC SIGNALS. AT ALL.
THAT MEANS WHAT>?
It means the PC, VGA jack is turned off.
bad cable
bad monitor.
The PC can also be bad VGA chips, or worse,.

your first failing here is not saying why you are using VGA jack
is the Laptop screen dead too> (my other shoe falls off)
dang that be nice to know , no?
or like we do run that VGA to a projector? for say doing power point presentations, (done many before retired)
RTM, the manual is free to read any time of day, 24/7
each PC maker uses there own rules here, its there call
there design and their rules.
my HP its, Fn+F4, (toggle:, internal, external ,both or auto)
but yours is Samsung, ask them. or learn to use google?

orange light mean your monitor not have input signal, check your computer vga card

The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?

If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.

Hope this helps!

Hi. The best way to hook your computers display to your LCD screen will be to use the VGA input socket. If your video card can support both S-video input and VGA, you can use either one but, the VGA is best for optimal resolution. This is the easy way to do this. Step one, connect the VGA cable to the computers video card and then, run the other end of this same cable to the VGA input slot on the LCD screen.Step 2, next you will make sure that the LCD's input selection is selected to show what is being transferred from the CPU video card by using the input button on the lcd remote control. The lcd(your tv) should be on VGA or PC input signal. Step 3, now, you Will have to also make sure that your video card is set to transfer this signal as well by pulling up your video cards software window and switch to the proper options. once this is done, you should get a signal. Be sure to use the VGA input/output ports on both the lcd television and your cpu for optimal transfer of the video stream. Here is a pic of your back panel. use the input port labeled I for good PC input quality.

Make sure you have the right input source selected. It may be looking for a signal from some input other than the one you're connected to. Beyond that, if it truly isn't seeing the input then you'll need to have the projector serviced.
