I finally picked up a 20" sony pvm. I did some research and it is the type that will accept a composite feed as sync. I currently have a custom scart box that switches to selected input, and pushes the video into a scart to hdmi adapter. This works great on all my consoles. I made a custom cable last night (scart female to bnc) to test out the monitor. I tried the nes, and the colors are just wrong. Almost like white is missing. I'm thinking at this point its the cable but I try my snes, works perfect.... NES - Bad colors - Audio buzzing SNES - Perfect Saturn - Perfect N64 - Perfect 3DO - horizontal scan lines ps1 - Didn't try Genesis - Audio Buzzing For the audio buzzing problem could this be because I tied all the grounds together in the cable I made? Should I separate all the grounds out? Any anybody have a clue whats wrong with the NES?
Try running the audio lines through a separate cable. Are you using an RGB-modded NES? If not, run it via composite video to the separate RCA composite video connector. If it still has issues, it's the console. Try using C-Sync in RGB mode instead of composite video as C-Sync is the best sync method for RGBS. It could be the PVM's settings need adjusting. I don't own a PVM so I wouldn't know much about them.
Its not the console, since the nes works perfectly fine going through my scart to hdmi. I am using Tim's RGB board.
Most likely the NES mod is to blame... Details about the mod, the cable, whether the 75 ohm terminators are enabled on the RGB input are kinda necessary to understand what's going on.
Just a standard front loader with his mod. I'm also using his cable that is supplied with the board. The cable I made simply is a scart female to rca jacks. All the grounds are tied together in this cable. And the corresponding RGB, Comp, Audio Left/Right are hooked up directly through. I havn't spent anytime on it. other then just plugging it in. I was hoping someone else has had a simular issue. I'll dive in deeper and see what I can find.
