Problems installing Neo-Bitz board...

I'm trying to install a Neo-Bitz board on my NEO-AES3-5 revision AES, but can't manage to get a decent component signal from it. When all is installed, the picture is very narrow, very poor and with a green tint (although composite works fine). I've checked out my outputs, but they're all soldered fine and I've tried installing the board by tapping the points from the underside of the motherboard, but end up with the same results.

Anyone know what the problem could be?

Aren't there pots on the NeoBitz that allow you to change the color settings?

Do you have any fixed resistors in? If not throw in some 124ohm or close to that in there.

On the Neobitz board there are 3 spots for the resistors.

If it doesn't have pots then there are fixed resistors on it. That was the case for the V2 board I got.

Trust me I know. I've been using them since 2005.

Reason why I said that is in the case he got the Neobitz from someone other than Jeff Kurtz. Sometimes modders use pots or resistors that aren't onboard and when doing so remove the onboard ones.

I did order the board from Jeff, although I'll post a pic of it tonight, along with a video of what the image quality looks like at the moment. I just hope I can get it working:crying:

Forgot to say that if you have a V2 Neobitz which is the green board then try turning off the sync cleaner if it's installed on your board.

Here's the board - it's a V2, but has no sync cleaner by the looks of it:

Here's a video of it at the moment, starting in composite, switching to component, resetting in component and resetting in composite for comparison:

...just thought watching the video - would it help switching the region of the AES on the Uni Bios?

Ah I see, LCD. Looks like the input levels are too high for the monitor. I would remove the onboard resistors and replace them with 250 ohm pots. If you want to just use fixed resistors I reccomend using 160 ohm resistors instead of the onboard 124ohms.

Forgot to say that the 160 ohm is what I used for my projector, if your picture is still too bright just increase the value a tad. Maybe yours is around 180 ohm.

Sorry, which resistors would require replacement? I'd prefer to install a pot, as I won't necessarily be using it on the monitor all the time.

In your pic it would be the bottom 3 on the left.
