![]() ![]() So my thoughts were.is this chip actually expecting Composite Sync or sync over Composite Video? My messing around with tying sync to the r,g,b lines feels incorrect and I haven't had a '100%' stable combination yet. It's almost like high concentrations of those colors get a little more stable if they're given the sync line. But then the in-game menus will be unstable unless I tie it to a different line. I can tie pin 20 on the scart plug to my scart color lines and get varying stabilities of sync.for instance tying it to green gets the Dreamcast menu completely stable, tying it to blue gets the 'Sega' letter animation in Crazy Taxi stable. I can disconnect it and get the same picture. It feels like the C-Sync input to the chip has no influence on the sync. It'll be stable in some places/resolutions but not others. I get a relatively correct intensity black and white image off the luma channel (amped with an NTE85 transistor) but the sync is.weird. The system I've been testing with is a US ntsc Dreamcast, with a SCART lead (upon checking, it's wired for Composite sync to pin 20 SCART, not composite video) and I'm having sync issues with my SD 36' Trinitron. I was having some problems so I rebuilt it, focusing mainly on the luma line/amp first. I've hooked it up to a 5VDC power supply and attached a scart input. Hi there, I'm currently building an RGB to component box using the BA6592F. I still do not understand why without amps my 220 uf caps worked well but after the amp they kill the signals, as if they blocked most of it.Īt this point my fairly limited knowledge of electronics fail me. I still have the nasty DC offset on the Output, and i think its made worse by the amp. This is pretty cool but there is one problem left. ![]() It immediately turned the image Fugly washed out. Snes cpu rgb 01 mod#I made the whole thing on a breadboard and could switch a wire to bypass the amp ( Stock mod ) I would say the color and brightness are roughly the same on both, only one is Component and clearer. Then i had the Modded SNES and a Stock SNES run the same screen of Super mario world. Snes cpu rgb 01 tv#I compared with two TV side by side, I adjusted them so Image, color and brightness were pretty much the same. With amp on RED and BLUE and removing the trimpot on GREEN the colors and Brightness were GREAT!!! For some reason the CAPS interfered here so i removed them. Then i went and made a simple transistor amp for each of RED and BLUE. I used 220 uf caps and it filtered it out. OK guys I think I fixed the Color balance and brightness issue on my component mod here!įirstly, turns out there is a pretty large DC offset on the Chip output ( Red and blue ) Which makes the screen flash nastily when you connect/disconnect the cables live. ![]()
