I Have a Sharp Roku TV model # LC-43LB371U Manufactured April, 2015. I have had the same problem with Amazon Prime video icons being blank when I open the app. This has happened several times over the past year or so. I followed the suggestion to do a system restart on the TV and it worked. Sometimes restarting my Xfinity cable box has helped but not always. This time I went to the Home icon on my Roku remote then: SETTINGS -> SYSTEM -> POWER -> SYSTEM RESTART. When opening the Amazon Prime App, it took a few seconds but the icons came back.

I have had the same problem along with other missing icons or words on the the screen. This has happened since the last update and the only way to fix it is pull the power plug. Then it works fine until it's turned off and it's does the same thing.
I had this problem with my Amazon Prime app and I fixed it. Thankfully, another post mentioned that the older Roku devices - whether the box or the RokuTV - had limited memory for today's apps. That got me thinking.
I went into my main screen and counted how many apps I had installed since I'd bought the Roku TV. There were 19. Many of these were channels that I tried and not liked, or just quit watching.
I then removed 11 of the 19 installed apps - each of which of course takes up memory by being on the device. I then pulled out the power cord and allowed a bit for the electronics within to lose charge and voltage.
When I plugged the Roku TV in everything was now fine. Memory restored, thumbnails restored.
While my issue was with Amazon Prime, I'm certain losing the thumbnail image could occur in any app.
I had struggled with this for quite a while until I figured out why the Roku TV was not showing the thumbnail pictures. I had posted on this previously - somewhere around here?
The issue is that the older Roku devices - standalone or TV - did not have enough memory within them to support the downloaded code within them getting larger. The code getting larger comes from two sources: as suppliers update their code from time-to-time they inevitably make the size of the code grow - and - as time goes on you add more access apps to your Roku to get more channels.
Both of these use more memory. When memory gets insufficient, the actual operation code of the device is protected so that it at least continues to work. Sacrificed is the nice pictures in the thumbnails.
The Solution. You cannot do anything about the bloat occurring in the apps, only the channel software providers can do that. But you can delete all those loaded apps that you don't really use or want. When I started the process, I had 23 apps loaded. I deleted entirely 12 of those, leaving the "essential" 11. Reset.
The problem went away immediately and has never returned.
Also, remember that if you change your mind and want an app back, you can re-add it at any time.
I only have a bare minimum of apps, maybe 10 so I don't think that's it. I still think it's a bug that needs to be fixed. Also this TV is only a few years old (4k/HDR) it's not an old ROKU device at all. I've tried everything from turning off fast-startup, removed as many apps as possible. It's been occurring for a while.. It's not consistent, but when I normally lose the icons is when I exit antenna viewing. When it happens, if I launch another app like YoutubeTV or Tablo the icons return when exiting those apps.
