I did’nt know you could still buy a WD Elements Play 2TB ? (It’s a pretty old device … basically a GEN1 + HDD in a plastic box)
… ebay special perhaps ? (which might explain the HDMI not working) perhaps ?
I guess the only other question is have you tried another device (Bluray,PS3,Xbox etc) connected to the TV via HDMI (just to make sure it’s not the TV) ?
P.S. This is the WDTV Live Hub forum … as you may well know, because the WD Elements Play Forum has been Archived (device is no longer supported … It’s a read-only section now)
Who knows, you may find something in there which relates to you problem
