Clim, I was just able to try GC via svideo last night, and used the 240p suite to switch full color screens. Even on the newest model "Ultravision Digital" unit, Im seeing the same behaviour. Its almost like the set loses sync for an instant when switching to full white screens. Maybe the standard Svideo signal is overdriving / clipping the input on the video demux / jungle circuit. My guess would be to add some resistance to the luma / Y input circuit on the TV. Dont know when I'll be able to play with that though.Climhazard wrote:Hey Josh, I'm the guy you sold those 2 sets to.Josh128 wrote:Oh crap, I hadnt considered that-- this could very well be an S-video feed.

That is indeed just straight s-video from the SNES. Both sets look great!
I've had a chance to do some more testing this morning and I have noticed one issue with the s-video input. Whenever there is a bright flash on screen or a game goes suddenly from a dark screen to a very bright screen the whole screen will flicker, almost like the TV is losing sync for just a fraction of a second.
Here's a short video example.

I've tested SNES, PS1, and Sega Saturn so far and it's happened on all of them so it's not a console issue. It also only happens on the s-video input, composite works perfectly fine. I don't currently have anything on hand to test out the VGA input.
I'll try to open her up once I have more time this weekend and look for anything loose but if anyone has a more specific idea on what to look for I would appreciate it. I'm far from an expert on CRTs, especially consumer sets, my experience is limited to doing a few recaps and manual deflection adjustments on some older arcade monitors.
yatzr - Do you have an svideo capable SNES, GC or DC you could try this same test on your set(s)? Curious to see if this is a universal issue or just affects some units.
