MP3 Cover Graphics

I use Serviio to play a lot of mp3 tunes off my laptop on my Samsung smart TV. Any CDs I rip I always use Mp3tag to add a cover graphic that shows on the screen. Today I was messing with the TV audio output to try and get optical audio to work on my receiver and when I restored everything to the way it was, I now don't see the cover graphics on the screen, only a generic music note or video symbo or picture symbol. Before Serviio I used Samsung Allshare and I found it took a long time to populate new audio and video I put on my laptop, but Serviio is almost instant Seeing as I have over 3000 songs, 300 videos and 200 images on my laptop, will it take some time for the cover graphics to appear on my TV? Or is there something else I can do? I've rebooted my laptop and the TV, but it made no difference. Is there something I can do on my Serviio Console to fix this?

I solved the problem. Nothing to do with Serviio. Resetting the TV fixed it.
