RADIO green 20A fuse has been removed and placed back. It looks fine by observation - no damages, no color changes. I presume there is the only one fuse, which must be inspected, and there is no such thing as a separate touchscreen fuse, right? Many thanks.

The only one 20A RADIO fuse looks OK to me.
