Facing TV Problems? Ask a TV Technician.
Hello, Your TV does not support MLB and there is no update to correct this, it's simply not on the list for supported TV's. That said, you need to use an HDMI (not a UHM) cable from your laptop to your TV's HDMI port and then select that port and view the content from MLB directly from the laptop to your TV.
if you get stuck simply reply back with specifically where you are getting stuck and we can proceed.
Alternatively you can purchase a streaming box (there are too many to recommend a single unit), such as Roku, Google Chromecast, etc. etc. that supports Major League Baseball and then simply connect that device to the TV's HDMI ports to view on the set.
