Problems with 2 Port KVM Switch with Built-In KVM Cables
I just purchased this item and I have connected it to both CPU's which need to be functional for my daily use. My primary CPU is functional, however, when I try to toggle back and forth between the 2 CPU's, I receive a this pop-up on a black screen: "Message: No Signal". I have checked all the wires between the 2 CPU's and they all appear to be intact and correct. Both CPU's are receiving power. Help!

Re: Problems with 2 Port KVM Switch with Built-In KVM...
The monitor is not detecting the video signal from your computer. Assuming both of your computer video cards have been tested and really work I would try the following:
Try switching the cable sets that connect the PCs to the switch. If the problem follows the cable set then it?s likely the cause. If not then try switching the cables that plug into the switch so that PC#1 is now connected to the port where PC#2 originally was and vice versa. Again if the problem stays at the same position then I would suspect a defective switchbox. If it doesn?t then you probably have an issue with one of your PCs video cards.
I know this is two months late but perhaps but hope this helps you or someone else researching a similar problem.

ask yourself -- do you really need the item
Is it essential to your daily needs
can you afford it
how are you going to move it
why are you buying it
have you been influenced by friends , neighbours, advertising that it is a good deal
why are you hesitating about the decision because that takes you right back to -- do you really need it ?
Have the fault codes read. Replace faulty items. Use only genuine items as non-genuine replacement are not always compatible with the OEM fitted CPU units. Look for position sensor with intermittent fault. Check all wire connectors for loose or dirty.
code p0352 refers to ignition coil B primary/secondary--circuit mal function==causes --wiring---ignition coil --ECM Replace with genuine items only as aftermarket units are not always compatible with the settings in the CPU.

measuring 12v at the psu is not enough.
the psu have several voltage outputs ranging from 12volts to 3.3 volts and maybe even 2.2 volts..
firstly, check all onboard USB ports, a bent or shorted pin in a USB port will prevent the psu from operating.
next, the psu has a safety connection to the mainboard, this is called the power good signal ( pwrgd) and it is a signal from the psu to the mainboard and tells the mainboard that everything in the psu is functioning correctly. If the powergood signal is lost ( drops from 5volts to zero volts) the mainboard will issue an interuppt to the cpu and the cpu will shut down, this will also shut the board down to prevent damage and data loss. mainboards all use pretty much the same connectors so your board will have either a 20 pin power connector or a 24 pin one. It may also have an additional 4 pin connector to power the cpu and northbridge functions.
use a known good psu and plug this into your board along with the 4 pin connector and attempt a switch on. If the system begins to boot, replace the psu. if not, try unplugging or removing everything connected to the board, pay special attention to expansion cards and usb ports.
remove the ram sticks and video cards if fitted, then attempt to boot again. if the system does not respond, replace the main board. if it now begins to boot, refit everything one item at a time and try starting the machine. turn off before refitting the next item and start the machine up again. when you get to the problem item, the machine will stop starting.
If all else fails, replace the mainboard or take the machine to a reputable repairer..
