NTSC SNES on PAL TV issues

Post by MightyHellbeard »

Hi! I've been trying my damndest to get an imported (US) NTSC Super Nintendo work on my TV set. I live in Sweden and own a Grundig Elegance 70 Flat (MFW 70-2501 8 Dolby) 28" CRT from circa 2006 that I usually use for my retro consoles. I haven't owned any NTSC consoles before, but for PAL stuff this TV has been great. It has one RGB SCART AV port, one S-Video SCART port and one direct S-Video port. According to the official specs it supports NTSC playback, so I assumed it would be able to handle the American SNES.

I started off with the US Super Nintendo and an official Super Famicom S-Video cable that I imported from Japan. No matter which port I hooked it up to - directly to an S-Video port, through a SCART block to AV2 (S-Video SCART) or a SCART block to the RGB-SCART port - I got a black and white picture. After doing some reading I guessed that my TV wanted RGB for NTSC playback, and ordered a new cable. This time I ordered a custom RGB SCART wired for NTSC consoles with pure sync. This cable arrived today, and lo and behold there was color!

However, one issue remains: the picture is horriby squashed. I found a picture comparing PAL and NTSC aspect ratios for Super Mario World, and added in how it looks on my TV:

The one to the right, with the huge black area at the bottom, is what I get. Is this simply my TV not being able to handle an NTSC signal, despite the service manual etc claiming it can? Is there anything I can do about it, save getting a new TV? It's been great for all of my PAL stuff so I am reluctant to change it. It's also pretty new (~10 years old). I've looked around in the settings menus to see if there's anything there, but they're all very sparse. There's not really any way to stretch the image vertically - I mean, there's aspect ratio settings (of course), but that doesn't seem to be the problem here.

I also own a modern LCD Sony TV (w805 series) with a SCART port, but hooking the SNES up to that TV is just a flickerfest. You can barely see the picture since every other frame is black. Unless there's something obvious I'm missing there, the LCD option seems like a no-go. Besides, it has the same problem as illustrated above as well, and I'd really prefer playing the SNES on a CRT.

Any ideads? I'd be very grateful for any help!

Are you playing NTSC/JAP games on the NTSC system ?

Whats in the picture looks like you are getting PAL.
I think maybe your tv is stretching the NTSC video into a PAL resolution.
PAL 4:3 704×576
NTSC 4:3 704×480

Can't speak for your Grundig CRT, but your Sony W805 certainly shouldn't have any problems like you describe.

Any chance you're trying to use your PAL SNES PSU with the NTSC SNES ?

No, it's a regular US SNES with carts that I've imported seperately. Every component is American and bought seperately from US Ebay sellers, excet for the unit itself, which I found in a thrift store over here. Maybe someone's modified the unit, but that would be odd. I'm suspecting that the TV can't handle the NTSC signal, though that doesn't explain the issues with the Sony LCD. I've ordered a Super Famicom off Ebay, so we'll see if that unit give me the same results. If both units produce the same warped picture I'll have to look into what's up with the TV's.

It looks like a PAL signal being drawn from line 1. Which is really odd since TV's always centre the image.
