It's likely that the HDMI output may not be supported. Some of the Media Drives have "computing" options, but many of them can only be connected through RCA, and sometimes USB or through a network.
This is more of an educated suggestion (if you will) based on my limited knowledge, so if anyone else has anything to add, I welcome it.
I tried all possible ways to solve this problem but i cant solve it.Here is my problem.When i use RCA to connect WD media center to my Samsung LE40N87BDX LCD TV there is no problem,however if i try to connect it through HDMI interface TV cant take signal.(When i connect my laptop through the same HDMI cable there is no problem.)Any help would be appreciated.
