2.3 Gingerbread – Getting a black screen when I play YouTube videos in the YouTube app

I have BSNL Penta Tablet with 2.3.7 installed on it. Every time I try to watch the video in the YouTube application. Play the video with audio only. Only the black screen appears in the video tab but it is never displayed.

What could be the reason for this kind of strange behavior?

Does the YouTube application have any errors or does the BSN Penta tab have some problems?

YouTube is the essential application in any tab, since it offers everything you want on the big screen.

Can anyone tell me how to solve these problems?
