Hello, all - new guy here with a question (that never happens, huh?)

Hi, all. Been interested in RC for a while, finally got around to doing something about it. I have a 200QX that now has a carbon fiber replacement frame (primarily due to my lack of skill as a 'pilot') and am in the process of building a 250 class quad with video recording / fpv capabilities. My question for now anyway, is about the electronics gear I have. I have an ImmersionRc 5800 UNO receiver, 720 TVL camera, and TS351 Transmitter. My little 9" TV monitor only sees scrambled, useless snow on the screen. I've tried a number of different 'channels', and just don't know what to do - I'm no electronics guy. I'm powering the monitor and receiver off the same power supply, and the transmitter / camera off a lipo. Could it be that one piece of equipment is transmitting / receiving on PAL and another NTSC, or do these items automatically accept / convert either? If anyone has any idea as to how i can get useful video, I'd appreciate it.

Usually they these things automatically switch over, though this is not always the case. I like to test with an AVI feed as apposed to a camera, like one that comes from a DVD player. Is your transmitter compatible with the receiver, becasue not only od they have to be the same frequency (2.5 or 5.8 are most common), they have to be the same channel.
 
well, i managed to get an image (acceptable) by powering my camera off one of those inexpensive dc power supplies available of the 'bay', not off the tx unit. the power supply has been extremely handy, and i'm just getting started. i think the transmitter is not supplying enough power (it outputs 5V, apparently, and this little CCD camera needs 12V, so i finally caught on to the math - i'm NO electronics guy). then, after damaging a dip switch on the transmitter, i bricked it and let the magic smoke out. waiting for another tx unit. now, to re-figure how to power the tx and cam, separately, apparently - or buy another cam, a 5V that will probably have to be CMOS. Learning.

You can pull power strait off of the battery if just takes 12v and you have a 3S. If you have a 4s, then I'd use some sort of step down, I use these for everything, I love them, but you can find something made just for FPV.
