Upscale issue

[Ruskino]

I've purchased a scart to hd upscale box (as recommended on a popular Saturn blog), but when I plugged it in last night, the screen was predominantly red. After some playing around (30 mins), it went normal, and I was enjoying all my classics on the big screen.

However, when I booted up this morning, back to red. I can't work out what it is.

Any ideas?

bad connection either in the cable or the scaler itself.
