I'm in the UK and have a PAL Sony Trinitron KV-32LS36U, which belongs to the same "LS" and ending with "U" line as the original thread posters TV with the colour issue. The set is perfectly capable of/designed to handle NTSC signals and 60hz, as well as full RGB euroscart.
I too have the EXACT same colour issue, when using a CSYNC RGB Scart cable designed for/with my NTSC Super Famicom (Japanese) on my set, the Picture is Clear, no wobble when a powered source is displayed, but the COLOUR ACCURACY is off. Everything seems slightly more...green than it should be, but by far the clearest issue is that some Reds appear Orange/pink. This is particularly evident on the Super Mario World title screen and in Super Mario RPG when seeing the red part of Mario's clothes.
I know that neither the 1CHIP 03 nor the SNES MINI/SFC JR systems can output Csync/pure without modding, and the same applies to the PAL SNES systems. But I'm trying to get CSYNC with my 1CHIP 01 NTSC Super Famicom, which is 100% compatible - without the need to mod - with CSYNC (as far as I know,) and I'm only interested in NTSC anyway.
I'm using Original American NTSC games and PAL games to test, not Japanese ones. I also used my SD2SNES, with no difference on Super Mario World via that. I got ALL my CSYNC/PURE SYNC RGB and SYNC ON LUMA RGB cables - both with Euroscart output - from http://www.retrogamingcables.co.uk
I presently have a Sync on Luma Cable which I used with my old PAL SNES and was designed for PAL, and the colour is perfect on that when used with my NTSC Super Famicoms, but I'm unclear on if it's OK (No risks etc?) to use a PAL Luma Sync scart with an NTSC Japanese Super Famicom.
When I access the SERVICE MODE on my CRT, there is a function under the "Design" option called "CDEC," and when I alter the value to 0000, 0001 or 1000, it improves the colour accuaracy drastically, making the Green effect disappear, BUT the Reds are STILL weak, looking orange/pinkish instead of the strong red expected. ALSO, the moment I either switch the tv to standby and back on, OR switch off the service menu back to either the "TT" screen with the "_" and "-" lines and the numbers and stuff that comes up when the TV first switches on in Service Mode from Standby, the effect of the "CDEC" value change is reset, and when I return to the "Design" menu, the value is where it was before I made the change. Of course, this change, even if it DID stay, doesn't solve the RED issue properly.
Just to be HELPFUL, I ACCESSED the SERVICE MENU or ENGINEER MENU by pressing the following buttons, ONE AT A TIME, RELATIVELY SLOWLY, WHILE THE TV WAS IN STANDBY MODE: i+, 5, VOL+, (_). The First button is known as INFORMATION, the Second is the Number Five, the third Volume up, and the Last is the DISPLAY button, which Looks Like a BLANK TV Screen. Learning this myself took me a couple of days of searching on and off across the net, and funnily enough the answer was elsewhere on these very forms.
I should make it clear that BOTH my 1 chip 01 NTSC Super Famicom AND my SNS APU01 NTSC SUPER FAMICOM (which is NOT a 1chip) have the SAME Colour issue on this TV set WHEN USING the NTSC CSYNC euroscart, as does my Playstation 2 SLIM's have their own colour tone accuracy problems as well, though not exactly the same, both PAL and NTSC PS2's using the CSYNC cable for them. With them though, a pale BLUE tinge appeared in brilliant white screens in games, notably in Shadow Hearts, for example.
Again, Luma Sync euroscart cables for each system were perfect with the Playstations and my original PAL SNES. (I have three SNES units in total now...and a SUPABOY.)
I should ALSO make it clear that I have tested my Super Famicom NTSC 1chip 01 with its CSYNC RGB scart on my HDTV and the colours were fine. I also own a small phillips CRT, but the image won't show at all via csync on that set, and a SD Plasma screen by TECHWOOD, but I haven't tested that yet.
So if it IS the CRT trinitron that doesn't like CSYNC, how can I FIX this? Aren't ALL RGB enabled euroscart CRT's - Certainly a high class Trinitron - capable of CSYNC? I've had no other issues with the set.
I too can post photos upon request, and would like to compare my problem to the original thread posters Colour issue, perhaps we can help each other?
If anyone else has any ideas, I'd GREATLY appreciate it and Thanks for any help offered. Cheers.
