how to fix no input signal error message

Verify the monitor cable is connected correctly and securely on the back of the monitor and the back of the computer. The monitor cable connects to the back of your computer using either a VGA, DVI, HDMI, or DisplayPort connector. The pictures below are examples of the VGA, DVI, HDMI, and DisplayPort connectors on a video card.

Verify the monitor cable is not loose by disconnecting the cable from the back of the monitor and reconnect the cable. It's also a good idea to rock the cable back and forth to make sure it's not loose.

When disconnecting the cable, make sure none of the cable's pins are bent by examining the end of the cable. If any of the cable's pins are bent or broken, the cable may be defective and should be replaced.

Next, disconnect the monitor cable from the back of the computer and reconnect the cable. When connecting the cable to the computer, ensure the cable connection is tight. With a VGA or DVI style connector, like the ones shown above, screws can be tightened and hold the connector in place.

Some computers may have an onboard video and a video card. When working with this type of computer, you'll have two different connections for your monitor on the back of your computer. If you see more than one VGA, DVI, HDMI, or DisplayPort connector and the monitor is not working, try the other connector.

Newer monitors are capable of connecting to a computer using a VGA, DVI, HDMI, or DisplayPort connector. For these types of monitors, the correct input selection needs to be used. Access the settings on the monitor using the buttons on the front or bottom edge of the monitor. Look for options to select the type of connector (e.g., VGA, DVI, HDMI, or DisplayPort), and select the cable your monitor uses.

If the connections appear to be correct, either the monitor or the video card is likely bad. It's also possible that the motherboard in the computer is defective, preventing a signal from getting to the video card and monitor. To test what component is bad, either connect a different monitor to your computer or connect your monitor to a different computer. We recommend testing the motherboard for any issues, as well. See: How to test a computer motherboard and CPU for failures.

If you believe your video card is bad and your computer has an onboard video, the motherboard needs to be replaced. You could also install a new video card instead of replacing the motherboard. See: How to install a computer video card.

Verify your computer is getting past the POST process and that it is starting up. The "No input signal" message can sometimes appear if the POST process is failing, and the computer cannot boot properly.

If the POST process is failing and the computer is not starting up, the motherboard could be at fault. A short in the motherboard or a bad capacitor are common causes for a computer motherboard to not pass the POST process.

If the monitor works for a while, then stops working and displays the "No input signal" message, the monitor or computer may be overheating. In the event of the monitor overheats, it stops working to prevent further damage. If the computer overheats, the computer may stop sending a signal to the monitor, and may also shut down to prevent further damage to the computer hardware.

Fixing a monitor that is overheating is generally not worthwhile. The cost to fix it is likely more than the cost of buying a new monitor. For that reason, we recommend replacing an overheating monitor.

If the computer is overheating, the fans that keep the processor, video card, or power supply cool may have failed. Check the fans to see if they are spinning. If they are not spinning at all when the computer is turned on, the fans need to be replaced. If the fans are spinning, use a software diagnostic tool, like HWMonitor, to determine if the fans are spinning at the correct RPM. It is possible that the fans are not spinning fast enough, indicating they are bad or full of dust and need to be cleaned or replaced.

For a video card or power supply, the fans are usually integrated into the hardware and not easily replaced, if they can be replaced at all. You may need to replace the power supply or video card to fix the overheating problem.

Circuit networks are built using red or green wire, and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains. Each circuit network contains a channel for every kind of item, as well as 48 extra virtual signals which act as user-definable channels. 'Everything', 'Anything' and 'Each' are also available wildcards.

Senders broadcast the amount of items or fluids they contain or other data definable by the player. Each amount is broadcast as a numeric value on a 'channel' corresponding to the item. For example, a Storage Tank containing 1000 Crude Oil will broadcast 1000 on the Crude Oil channel.

The channels are separated from each other, so each network can simultaneously carry a number for each item and fluid in the game, and for each of the extra user-defined channels (digits 0-9, letters A-Z, and 9 different colors). All unused channels have the value zero.

All wires of the same color which are connected together by junctions form a network, i.e. they will pass their signals to each other. For example, if two red wires are connected to the same combinator input, each wire receives the content from the other. This can result in feedback if care is not taken; see Feedback (under arithmetic combinator, below) for discussion.

Numbers are in the signed 32 bit integer range, i.e. from -2147483648 to 2147483647 inclusive, and are encoded in two's complement representation. The numbers wrap around on overflow, so e.g. 2147483647 + 10 becomes -2147483639. When entering a number in a combinator it can appear to exceed the 32 bit limit until the GUI is closed, at which point the number will overflow/underflow. [1]

Receiving devices sum all signals from each wire connected to them, even red and green wires. For example, if an inserter is connected to a red wire carrying a signal for 20 copper plates and a green wire with 10 copper plates, the input signal set for that receiver will be 30 copper plates.

Multiple wires of the same color will share & sum their signals. For example, 3 chests A, B and C connected in a row (A -> B -> C) with green wire will output the sum of their contents along any green wire connected to any of the chests. However, if a red wire connects chest A to an inserter, that inserter will only be given the contents of A as its input signal.

Each device that is able to be connected to a circuit network has a icon located in the top right corner of its info pane. Clicking this icon will display the available circuit network options for that device (note: a red or green wire must be connected, otherwise the message "not connected" will display instead). Clicking the icon next to it, the device can be connected to a logistic network if in range of one, which also allows conditions to be set.

A circuit network consists only of those devices connected together with the same color wire. Wire can be strung directly from device to device, or across any intervening power poles. Wire length is limited by its previous connection.

Note that each connected set of wires forms a separate network. For example, it's entirely possible to have four red-wire networks and three green-wire networks. If red and green wires happen to touch the same power pole or device, the red and green networks will remain separate and will not link up. However, two red cables or two green cables will link if they touch. Use different colored cables to separate networks in close proximity.

48 virtual signals can be sent over a network. They include the digits zero through nine, the letters A through Z, a check-mark, dot and info icon, and the colors red, green, blue, yellow, magenta, cyan, white, gray and black.

Everything can be used on the left side in conditionals. The condition will be true when the condition is true for each input signal. The condition is also true if there are no signals. This means that the everything signal behaves as universal quantification.

The output of a decider combinator may also use everything, unless the input is set to each. When used, the combinator will output signal on every channel with non-zero input as long as the condition is true; the value will either be the input value or 1, depending on the corresponding setting.

Anything can be used on the left side of conditions. It will be false when there are no inputs. The condition will be true when the condition is true for at least one signal. This means the anything signal behaves as existential quantification.

Each can only be used in left input side and output of decider and arithmetic combinators. The signal can only be used as an output when also used as an input. When used in both the input and output, it makes a combinator perform its action on each input signal individually. The combinator will output the sum of each of the actions if only used in the input.

The logistic network used by logistic robots is essentially a third network (a wireless one), along with the green and red wired networks. The logistic network is based on proximity to a central roboport.
