Spectrum lost colour on composite but gained stripes on YUV
Posted: Tue Jul 25, 2023 1:48 am
Hi,
I've got a Spectrum 48K which has got a black and white composite picture, and a stripey picture via YUV out (RGBTOHDMI converter).
Both were working fine previously but I am worried I might have zapped something through poor edge connector hygiene. The RGBTOHDMI is supplied YUV video from an edge connector cable/adapter (which works fine with another machine), and then samples the picture to create a HDMI signal to an LCD screen. It's difficult to make out but it looks like it also has lost some colours, especially from odd/even lines, white seems to be there, but I think the TV screen is showing something different. Any ideas where to start?
Many thanks as always, Will
