rednakes1 Posted May 18, 2017 Share Posted May 18, 2017 I did a composite mod last year in my CV using the kit from coolretroprojects. Unfortunately the kit actually made it look worse so I went back to my coax connection. Now that I have some time I would like to investigate this further. Also I could also attempt a different mod using my own parts. For instance, I see a fair bit of noise in the screen with the composite output... kind of like faint diagonal lines one moment, then horizontal lines, then other types of interference patterns. It's not horrible but the changing noise gets annoying on games with blue backgrounds such as the Evolution title screen. Anyone else had this experience? Ideas?

Keatah Posted May 18, 2017 Share Posted May 18, 2017 I wonder if a lot of these early systems relied on the Lo-Fi characteristics of composite and RF to mask a lot of the digital noise. On purpose. And modern day mods remove that filtering action. Quote Link to comment Share on other sites More sharing options...
Bmack36 Posted May 18, 2017 Share Posted May 18, 2017 Do you have a picture of the mod installed? Where did you tap your connections? The second picture shows How I usually install mine. https://colecovisionupgradesandsales.ecwid.com/#!/Composite-Mod-DIY/p/70365537/category=20695415 Make sure to cut a hole in the RF box for the wires to come out so you can put the top shield of the RF box back on. 1 Quote Link to comment Share on other sites More sharing options...
rednakes1 Posted May 18, 2017 Author Share Posted May 18, 2017 (edited) This is the picture I took last year, so here are the connections. (See attached) The wires are really thin in this kit so I wonder if that has any impact. I did put the RF shield cover back on and routed the wires out a hole, but that makes no difference. EDIT: From top to bottom, the wiring is: Ground, Audio, Video, 12V Edited May 18, 2017 by rednakes1 Quote Link to comment Share on other sites More sharing options...
