Scanning Slides

Hello!
I'm new to this forum and I have an odd problem with my Epson ET-2750.
I would like to use the ET-2750 to scan some old slides, so I tried to find a transparency unit.
However, since the ET-2750 is discontinued, it would seem so is the transparency unit.
So I have purchased a LED Light Pad, for the backlight illumination.
I then placed some slides on the screen with the light pad on top, the scan was washed out.
I then tried different pieces of paper and card to reduce the intensivity of the backlight.
I found a sheet of 200gsm card seemed to work quite well, colours needed a bit of saturation and the lighting adjusting.
The scans were slightly dark but useable, so I thought i9t's sorted.
I then changed the slides from the Kodachrome one's to some Fujichrome ones.
Now all the scans come out in monochrome, I then tried some Boots Slides and the same thing happened.
All scans are monochrome, i tired different intensities of backlight but still all monochrome.
If I place the slides on the light pad then all the colours show up.
Any ideas would be helpful, thank you?

The scanner has a monochrome sensor and switched R, G, and B LED illumination to detect colors. You are only going to get monochrome scans with a separate light source.

It's odd that the Kodachrome slides scanned in colour.

The scanner must have been seeing more of its own light. Maybe Kodachrome is more reflective or your set up was different.

You could try something like this, but results from a cheap scanner and lighting kludge will never be great.

Most people digitise slides and negatives with a camera.

Thank you, for the information. I do have a small slide scanner, but it is hit and miss that I thought i could do 12 at a time then just crop them. But heho it's not to be. I can always set my camera up on a trpod and use the light pad as a source for that.
Cheers,
