I have just purchased a used computer and it will not send a signal to either monitor that I have. It has an Intel D845HV mobo, Nvidia Geforce2 MX 100/200, pentuim 4. I first hooked it up to my new monitor which is an HP w2408h LCD and it worked but then i turned off the computer because the keyboard would not work and after turning it on again, the monitor displayed that the VGA and HDI was not receiving a signal. So I then hooked up my old tube monitor to it and it also doesn't work; says ''Video cable connected?'' I know the Nvidia video card is ok because I took it out and put it in my older computer which works fine with its tube monior. So, with this newer computer I cant get to the desktop or even see it first boot up to use the F8, etc commands. Any help would be appreciated. TY

I have the same problem with at least 6 GV800s that are clone...I dont know if the originals will have the same problem. The problems occured after thunderstikes. All went DEAD and send them to China for repair. I have a few cameras connected to this card using shielded cable...and some others using UTP cable using video balloons. The UTP is not shielded and I start suspecting the damage is from these cameras.
I had the same exact problem with my PC to TV only showing colored bars. I watched a lot of videos/read many forums to try to figure this out.
The solution was very simple.
I did two things wrong: 1) I was using a different VGA cable then the one that came with the unit. 2) My PC resolution was not set to 1024x768 so my tv couldnt read it.
MAKE SURE you use the VGA y-cable provided with the unit and MAKE SURE you plug the one labeled "PC" into your PC (as opposed to the other blue one labeled "monitor," which i dont use. it DOES make a difference)
Then i press fn+F7 (my particular hot key for external monitor display. every comp is different, so check yours online/in the manual) on my laptop. I had to enable the "XGA 1024x768" option under the "fn+F7 settings." (all i did was check off a box for this option and click OK. then i was able to use that option)
Once i did this, POOF!!!! Away went the annoying colored bars and up came my computer!! HOORAY!!!
So lets recap: 1) use the provided y-cable to connect PC to TVtoPC and plug them in according to its label. 2) make sure your hot key settings has the option for "Presentation on Projector and Notebok : XGA 1024x768" and enable it. (i assume xga=vga???) 3) once you click that resolution option, your picture should come up! (if not, then just reset the pc to tv and it should work!
I hope this helps you with your problem!!
PS: I read that the computer needs to have a screen refresh rate of 60 hz. This is accessable thru right click->preferences->display settings->advanced settings->monitor->refresh rate. I didnt need to mess with this cuz my PC already had that setting. the resolution was the actual problem.
PS #2: I saw many videos on youtube saying that you needed to switch to monitor 2 under the display settings. this is contrary to my setup. I am still using monitor 1. just with the 1024x768 res. instead of my normal 1400x1050 resolution.
Sorry if this is really wordy! Hope it helps you solve your problem and keep you from throwing your PC to TV out the window!!
You may need to switch your laptop monitor to an external monitor using the Fn + F5 keys or similar -see your laptop manual. This will send the VGA signal to the HD-15 VGA connector going to the converter.
The instructions that come with the unit doesn't address this.
I had the same problem. It turned out the issue was that I had the VGA Y-cable connectors between the PC and the KWorld box reversed. They look like they should be interchangeable, but they are not. A closer look at the cable connectors shows that one is marked "PC", one is marked "Monitor", and the 3rd is marked "SCAN CNVTR". Once I got them plugged into the right places, I got the screen image on the TV.
I had the same problem. I was going from PC -> Dvd recorder -> TV. I had the S-Video output from the averkey going via an adaptor into the DVD scart input. I discovered a setting within the DVD menu which could select between 's-video' and 'composite video' on the scart socket. (it appears that scart can carry either/or, I guess).
I changed from composite to s-video, and I got colour.
I think seeing a greyscale image indicates that the signal being sent is S-Video, but the equipment that is recieving it is expecting composite video.
