Videos; I hear em' but can't see em'

[Tazz]

This morning I could see & hear videos but now I can only hear em' on my android LG tablet. I cleared the history/cache and stuff and restarted the tablet and still can't see the video but I can hear the audio. I'm not having these problems with my iphone though. The only thing that's changed today is we got a new router/modem and got the internet speed upgraded from ATT. Any ideas? Is my tablet just a POS? Lol!
Thanks,
Tazz

Turn your volume up.

Turn your volume up.

I said I can hear the audio, I can't SEE the video.

Evidently it's not all videos. I just clicked on one thread where the video works just fine. WTF??? This is irritating.

Ok, I just noticed so far it's the videos posted from fakebook I can hear but not see.
