HI, everyone, i own a spectrum 48k with an AV Mod. It is fine aside from the fact that everything that appears on screen is b/n. I'm not an expert so i'm asking if there is a way to fix it. Thanks!

I assume you mean black and white.

Tell us more about your TV. Does it recognize the Spectrum’s output as a PAL signal? Have you tried connecting the Spectrum without the AV mod, via the RF output? Any other image issues other than the absence of color?

i tried it on a Funai 15" crt and on my Panasonic lcd with the same results. Via rf it gives disturbed signal only.

What’s the logic board revision (printed along the bottom edge of the PCB)?

I suggest you read through this little guide. Maybe even start with this.
