sony kd49x8505b media player

[paclark7267]

I am suddenly having problems with the media player on this T.V.

I have been ripping dvd, s  to my laptop mainly using MP4 format

Then copying to WD mycloud which connects to my wireless router then to tv as a media server

Up until today these were playing fine

Now I'm getting messages that media player not working

This is probably unrelated to what I'm doing as I'm also not getting the multitude of apps that are normally available

Any thoughts?
