Backup camera switching constantly?

**optikalefx** · 05-07-2011, 08:43 PM

I just hooked up a rear view camera to the backup camera wire on my lilliput 669. I've got HDMI input and then the camera on AV2 composite. The switching works fine except the monitor will constantly lose signal and say no input, then come back to normal HDMI input. LIke it doesn't switch to av2, but it just keeps losing connection.

This only happens while i have the av2 plugged into the camera.

Any idea whats going on?

Thanks!

any idea with that random image/blog post about ditching computers?!?

this seems just as vague as that blog post.

so how is the backup camera powered? is the reverse wire input connected to the shifter, or the reverse lamp? is the camera loosing video/power or is it a issue that is only happening on the display?

Haha, im not at liberty to speak on such images.

The backup camera is powered by switched filtered 12v from my m2atx in the computer. The backup wire is spliced into my reverse light. The camera really isn't the issue, its my normal PC video that seems to lose connection. Though i don't think it is losing connection, i think its just the monitor that THINKS its losing connection.

Ill have to test other inputs and see if it does the same thing, maybe i screwed the computer up today.

it could just be the hdmi connection for your motherboard --ironically, my brother and i just had this issue-- we wanted to watch a tv show on the tv-- first he tried his laptop(a msi something with graphics better then intel integrated-- something like ati radeon..)-- the tv connected/disconnected multiple times, and finally displayed his desktop.

i then tried my laptop(hp g60, intel integrated graphics) and the tv connected fine with no issues..

i think the tv and my brothers laptop were attempting to argue over which resolution they could/would display-- it is very possible that your hardware is doing the same thing.

does it make sense that it only started happening once the backup camera wire was attached and/or the composite video was now connected to the camera? It was fine before. I'm gonna have to test and see if unplugging the composite fixes it, if it does, then its gotta be a lilliput issue.

Unplugging composite video didn't help. But unplugging the backup wire did. So either something is hitting that wire with 12v randomly or the lilliput is messed up.
