RGB Mod TV - Jumping off point
Zebidee:
Pretty much any TV built in the last 40 years or so will have a jungle chip.
Usually there is also a separate OSD chip which feeds an RGB signal into the jungle. You can hijack that input with a little bit of cleverness, a few resistors/capacitors and maybe a switch. However some newer TVs have the OSD function incorporated into the jungle chip, denying that as an access point.
Jungle chips will obviously all have video inputs, but not necessarily RGB inputs. It is common to see primary inputs for composite video, maybe RF, but there are often svideo (Y/C) and/or component (YUV or YCbCr or YPbPr) pins available even if they aren't used. Sometimes you get lucky and find jungles with primary inputs for RGB, especially if made for the European market.
If you have a newer TV with OSD incorporated in the jungle and no RGB inputs, you'll probably have component inputs there. If you have access to a decent RGB to component transcoder like a GreenAntz then this is a good and easy option.
Otherwise, if there are no RGB inputs anywhere else, you'll need to inject the RGB to the neckboard inputs (ie RGB outputs from the jungle). This is the dodgiest way to do an RGB mod - it is definitely possible, but not for the faint hearted or new players. Main issue is you won't know what levels the signals need to be. Secondary issue is you lose any ability to use the OSD or remote to influence or select the signals. Could be operational safety issues as well.

Thanks. Ill take some detail shoots of the board and see if anything can be identified.
Im not sure how old it is, but it must be fairy old as it doesnt have an OSD, but came from a company how said they never really used it. And from the quality of the picture i find that to be true, just be noce if its possible to get RGB out of it.
The S-Video signal is nice however...

Everything will just be theory and fluff unless you add some details about your display, like brand and model number.
