This is kind of related to the OSSC but here goes…
I have a super famicom with a CSYNC RGB retrogaming scart cable, playing through a 26″ sony triniton crt.
I see quite a bit of colour “bleeding”, mostly on the reds
Can anyone tell me if this is the SNES, the cable or my display? Will I see this on the OSSC (when mine arrives :p)?

Difficult to say… what kind of SNES is it? (2-chip/1-chip)? Do other systems have colour bleed on that TV or only your SNES?October 9, 2017 at 2:14 AM #15817
Unsure as to type of SNES, but after looking for it, I can actually see the bleeding on my jap mega drive too.
I’ll try to eliminate parts of the chain (have a Shinybow scart>component convertor and a powered bandbridge scart switcher also)October 9, 2017 at 8:23 PM #15837
Do you have access to a flashcart on either SNES or Megadrive?October 9, 2017 at 11:43 PM #15848
Yes to both
I tried bypassing the scart switcher and still saw the bleeding so thats one component we can cross off

Can you try the colour bleed test in the 240p test suite?October 10, 2017 at 2:40 PM #15871
I have that on the MD though didn’t know about the colour bleed testOctober 11, 2017 at 10:53 AM #15890October 11, 2017 at 5:21 PM #15903
Red does look a little over-saturated, blue too You may need to look how to adjust convergence on your set. How to do this varies between sets so check around. If you do decide to open your CRT, always exercise caution as it contains very high voltage components that keep their charge even after the set has been powered off.October 12, 2017 at 12:21 AM #15923
Saturation might be the exposure from my phone camera
I can get into the service menu on my TV (Sony trintron) but I’m not sure what setting I’d need to change to adjust the bleeding
Opening up the set is a little above my pay grade I’m afraidOctober 19, 2017 at 12:14 AM #16166
You’re not saying which Trinitron model, but anyways, try to find the “HWD RED”, “HWD GREEN”, “HWD BLUE” options; they’re usually together with geometry options, though I’m not sure on NTSC models. Lower the RED value a bit and check it out. Over-driven colors (together with the focus) will normally need adjustments only possible by opening up the set, but you may alleviate a bit the problem with the service menu options.
