Re: No input signal
Hi, there is a posibility that the issue is caused by your system unit. NO INPUT SIGNAL occurs when system unit fails to start properly. One possible reason is the power good signal was not sent back by power supply to mother board. You can check for any shorts or grounded device in your system unit. If you can reseat all the cables (power cable, IDE cable), expansion cards, memory cards even microprocessor that will be good. Another thing you can try is to power cycle your computer. If you are not confident enough to do those stuff you can call your computer vendor and ask for assistance.

The video signal is not getting into your display.
Check the connections on both sides of your cable (display side and display card side). If that didn't help, switch off your PC, make sure youre display card is in its correct place (try taking it out and putting it back again). Switch on your PC and check again. If the problem continues, try replacing your display card.
Try checking the signal strength then run the scan again. Checking the DTV signal strength
You can check the DTV signal strength to determine if you need to adjust your antenna or digital cable input. The higher the signal strength, the less likely you are to experience picture degradation.To check the DTV signal strength:
1.Press MENU. The on-screen menu opens.
2.Press < or > to highlight Channel, then press v. The Channel menu opens. The DTV signal strength is shown at the bottom of the menu.
There is no signal coming from your PC. excuse some of the solutions as sounding dumb, but we have to explore all possibilities.
Check the power cable going into the computer Check the power input disconnect switch on the back of the power supply and make sure it is on If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped press power on the PC and make sure the lights are coming on.
now for the solutions that may actually help.
disconnect the power from the PC if the video is on a card, remove and re-seat the video card hook the power back up, connect the monitor and try again.
the CMOS on the computer may need to be reset. I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up. If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.
Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)
1 unplug Dazzle from USB. turn off pc, restart with out dazzle plugged in. shut down PC, restart then plug dazzle in after PC has restarted fully. if that don't work then go to step 2. ( sometimes using a different USB port works too)
2. uninstall it and reinstall it should work fine. i had the same problem and had to many things in the USB ports at the same time.
