RGB/YPbPr input card for JVC professional monitors like TM-H1950CG. Based on the original card, thus all resistors and capacitors have same reference ID as the original card. Only the power supply part is different. This is the base board, which supplies the actual “interface” electronics. You then need one of the input boards mentioned in the bottom of this post, OR solder directly to the pads on this board. If you’re not into SMD’s there’s a through-hole version here: https://www.oshpark.com/shared_projects/NHivAGjf
