Daddelretro Posted March 31, 2022 Share Posted March 31, 2022 I have 3 PAL Junior Consoles from different years. They all show block artifacts at edges. I tried different cables, power supplies, two tvs (5 and 10 years old) and a smalll external RF receiver. I modded one to AV Composite. Nothing brought any improvement. I'm wondering if this is "dow crawl"? Nothing is crawling, it's avery static patterm. Thanks for any support to understand and/or get rid of these artifcts.

alex_79 Posted March 31, 2022 Share Posted March 31, 2022 That's normal, although the LCD makes it a bit more evident than a CRT. It's the PAL equivalent of the color bleed that you get on NTSC consoles. S-video would make it less noticeable, but it would be still visible on areas with different colors but similar luminance. If you flip the TV-TYPE switch to B&W in "Pitfall" you'll see that artifact disappear. Quote Link to comment Share on other sites More sharing options...
Daddelretro Posted May 9, 2022 Author Share Posted May 9, 2022 Is there any kind of mod with which this can be avoided or reduced? Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted May 10, 2022 Share Posted May 10, 2022 S-video output pretty much eliminates this issue, assuming you install or have installed a UAV. Although this will also be more or less obvious based on TV or equipment used. An example is that when I plug most composite signals directly to the composite input on my game room LCD, then I don't see the blocks as much as I see severe bleeding or ghosting on the edges. Through my Extron, I see the blocks. But on S-video I do not. The RGB upgrade for the 2600 systems will prevent this as well, but that is a more costly solution but very impressive output.
