Check and make sure you have the correct input selected by switching the input. This is a function on the monitor.

what kind of power did you supply, it has to be a direct power source eg. you can hook it to the cigarette lighter terminals if it still does not respond try the battery terminal and change the channel , do not connect it to a cigarette lighter plug, it will not work because it need a high power source good luck

Have you connected 12v+ to the red AND blue leads? The blue lead also needs power; it acts as a "trigger" much like power amps for car stereo systems. In my application, I wanted it to come on only when I use reverse gear, so I connected the red lead to a keyed-on source, and the blue lead to the backup lights (long wire from trunk was easiest for me.) If you are using it for a GPS, or DVD player, then you will probably want to connect the blue lead to the same keyed-on source as the red lead. The monitor also has twin video input capability, so once it comes on, you need to make sure you have selected the correct video input. Have you connected 12v+ to the red AND blue leads?

Check to see if the power cable is also in the same place also check ebay and try typing in the model number in the back of the screen itself dont go by the model of computer. After you take off the screen behind it has the model number

Sorry, but no idea really, without seeing the unit and checking a few things. But usually the only thing that will keep a computer from starting at all, assuming power is available, is either a failed motherboard, bios, or hard drive.

sorry, it has been so long since we hooked it up i forgot. There were 2 hot wires going to the monitor, one did not go on automatically so i used the other. The unit works well, after several months.

I just checked the monitor and its box but neither state how much amperage it consumes. Use the 12V@3A power supply. It should handle the monitor just fine.

Send in for a new one...really! Or you could try to fix it by buying new boards; it is not the back light or power supply.

Make sure you've connected the pci-e power cable (one that have 4 pins) to the video card, you`ll find this cable on your power supply. If the PSU is a generic one, probably you`ll need to buy one to make your vga turn on properly

Check for loose wiring/loose fittings first. Second would be to try changing the resolution on screen. Last would be your monitor is going out. Let's hope that's not it.

sorry it took so long to get back, just make sure u got all the connectors plugged in and have a good power supply. try to test the power connectors if there not a name brand on something u know that works to rule out a fault power connector

Unplug the power and plug it back in. If you don't see a picture, it might be stuck in the wrong video mode. If it is, you might not be able to fix it without plugging it into a television that supports the mode it is currently in.

I've had two since purchased and I've never had any issues. Can imagine that's a monitor specific issue rather than a power issue, I'd say internal components are more likely to fail first over external if for some reason you are really stressing the PSU.

I would check that all connections are not loose. It sounds like you have the power usb cable plugged in but check it's connection as well. I'd suggest contacting the company if you have further problems.My monitor has worked flawless since installing the adapter. Sorry to hear you are having issues.

Not sure I understand what the problem is. This monitor runs by a power supply which can be plugged into a UPS like any other 120VAC device.

Make sure the PC is not defective and that all cables are plugged into the board. Disconnect all non essentials from the mobo....only leave RAM. CAN and CO Fan. Power on to see if it POST. Also make sure PSU us set to correct voltage of 110 and not 220

Make sure ur AC Adaptor or Battery can Supply 12 volts and at least 400 Miliamps and u hav an Active Video signal Transmitting to the monitor. the monitor automatically shuts down all circuits cept the video processor to save power wen no video is present but wen a video signal is detected the monitor will turn on the Screen. this is a nice feature as i plan to use it as a remote Viewfinder for my Camera. Note on powered camera, all cameras r powered wen working and the Rear view cameras DO Not supply power thru their video outputs On the stripped end of the Power line the red wire is Positive Make sure ur AC Adaptor or Battery can Supply 12 volts and at least 400 Miliamps and u hav an Active Video signal Transmitting to the monitor. the monitor automatically shuts down all circuits cept the video processor to save power wen no video is present but wen a video signal is detected the monitor will turn on the Screen. this is a nice feature as i plan to use it as a remote Viewfinder for my Camera.

It must be defective if you have it plugged into a working USB port and the ports on the monitor won't work. I've had mine quite a while and use the USB ports daily with no issues

Yes, this monitor should work if power is switched on. In the case of not producing sound try using a headphone with the available headphone jack.Add some volume.
