Hello,
I've geoereferenced a raster map using ArcGIS and exported it as GeoTIFF, however, I can't read it properly in FME data inspector, the image appears all black.
Have anyone before faced the same problem ?
Thank you.

Can you share the image with us? Is it supposed to be imagery or elevation data? GeoTIFF has many different settings (bit depth, byte order, indexed or not) and not every application supports all flavors. Generally FME seems to be handling it ok but you may have made a setting that's unsupported.
When you import the image in ArcGIS again, does it look ok?

Yes, it appears fine in ArcMAP when I import it, but on data inspector I get everything as black
Thanks

Here is a portion of the image, the same problem persists, the images appears fine in ArcMAP and QGIS but always black in FME Data Inspector

I looked at your raster data. It has 16 bit integer x 3 bands (GRAY16, UINT16, UINT16), the valid value range of each band is 0 to 255, and 256 is defined as Nodata.
FME reads cell values as-is, but FME Data Inspector doesn't seem to support display the band interpretation (GRAY16, UINT16, UINT16) as RGB color. You can check the interpretation and individual cell values on the Feature Information window of FME Data Inspector.
Since the cell values themselves seem to be read correctly, I don't think there is any problem.
If you need to see colored raster with FME Data Inspector anyway, try using the RasterInterpretationCoercer to change the raster interpretation to RGBA32.
