Newly bought lumafix makes vertical bars worse

Post by Linzino »

My newly bought lumafix makes the vertical bars much more visible (it is supposed to reduce or remove them).

Its three trimmers seem to have no effect on the picture.

I have installed the lumafix on Breadbin C64 with a SCART (composite) cable.
The Breadbin without the lumafix has slighly visible vertical bars, which I wanted to get rid of.

What is wrong with the lumafix? Have I done something wrong? What should I check?

First, you should check you are using the C64 Luma/Chroma cable (i.e., the 8 pin one), and not the 5 pin cable normally used also for the VIC-20.
