[Old guy new to digital cameras needs basic help!]

You'd have to go into the camera shooting menu's Film Simulation options. From there, you'll have the option to default to the Monochrome options. Keep in mind that once you shoot in monochrome, the pictures can't be reverted to color later. Here's a link to your camera's online manual. You'll also have the ability to download a PDF copy of the manual for yourself.

[X-T20 screen flickers on and off when attaching lens]

Have you tried to update or reflashing the camera's firmware? It's worth a shot to see if it fixes the problem.

Have you all tried to update or reflash your camera's firmware? That may correct the problem. 

[Firmware Problem]

Be sure to format the SD card within the camera first. Remove the card and use a USB reader to connect the SD card to the computer. With your computer, download and copy the FWUPxxxx.dat file into the root directory of the card. The camera should find it there during the firmware update.

[Memory Card Issue - X-T3]

Please let us know on what needed to repaired on your camera. Thanks!

[Memory Full issue]

What are the sizes and age of the SD cards? Have you tried updating the X-T3 to the latest firmware to see if that fixes your problem? I believe the latest firmware is v.210 (FWUP0019.dat) for the X-T3. Copy the firmware, downloaded from the Fujifilm support site, into the old PNY card that works to update the camera. Let us know if that worked for you. Good luck.

So, if I plug my battery grip, attached to the X-T3 body to charge, will it charge all 3 batteries, or just the 2 in the grip?

Thanks

Hank

I believe the USB-C port only charges the battery in the camera, but not the ones in the vertical grip. 

[Memory Card Issue - X-T3]

Slot will not accept memory card on X-T3.  It's not the card, tried several different cards and all were rejected and inserted fine in my X-Pro2

Anyone have a clue how this happened and how it can be fixed?

Thanks in advance.

Slot 1, 2, or both? Did anything happen to the camera the last time a card was inserted into the slots? Did you have problems initially ejecting the card from either slot?
