Note that the v4.x firmware My Cloud is OS3 not OS5.
How is the TV accessing the My Cloud? Using DLNA (My Cloud Twonky Media Server) or by SMB?
Have you checked to ensure you are not having a network or WiFI problem between the TV and the My Cloud?
There is a Twonky FAQ that has additional information and suggestions that may help if one is using the My Cloud Twonky Media Server.
