Hi! I understand you're seeing a black screen when trying to watch a channel on the PTV Sports app. Let's work through this together to get it sorted out.

To start, could you tell me if this black screen happens just on one specific channel or on all channels you try? Also, is this happening right after opening the app, or when you start streaming a live game?

Meanwhile, here are some simple steps you can try on your Windows device with WebKit browser and Windows 10:

1. Refresh the Stream: Sometimes the stream can get stuck loading. Try closing the app or browser tab completely and then reopening it.

2. Clear the Browser Cache: Cached data can sometimes cause streaming issues. You can clear the cache by going to your browser settings, finding the privacy or history section, and clearing cached images and files.

3. Check Internet Connection: Make sure your internet connection is stable. Streaming live sports needs a good bandwidth.

4. Update the App or Browser: If you are using a standalone PTV Sports app on Windows or a browser, ensure it is updated to the latest version.

5. Disable Browser Extensions: Sometimes extensions interfere with streaming. Try disabling any ad blockers or VPNs temporarily to see if that helps.

If after these steps the black screen persists, we can move on to advanced troubleshooting like checking your video drivers or app permissions.

Does that sound good? Let me know what you try, and if you can share more about exactly when the black screen shows up, that will help me assist you better.

i want its biss key

Thanks for asking about the BISS key for the PTV Sports app. Just to clarify, BISS keys are encryption keys used to decode satellite broadcast signals on certain receivers. The PTV Sports app streams content over the internet and doesn't require a BISS key to access channels.

If you're trying to watch PTV Sports via satellite on a receiver and need the BISS key, that information is typically not publicly shared, as it involves broadcast encryption rights and can vary by region.

Could you tell me more about how you are watching PTV Sports? Are you using the mobile or Windows app, or a satellite receiver? That way, I can guide you properly on how to access the channels you want.

Current working BISS key for PTV Sports app?

Thanks for your patience. As far as I know, the PTV Sports app doesn't use BISS keys because it streams content via the internet, not through encrypted satellite signals that require such keys. So, there isn’t a BISS key associated with the PTV Sports app itself.

If you're trying to watch PTV Sports on a satellite receiver and need a BISS key, I recommend contacting your satellite service provider or PTV's official support for guidance, as these keys can change and are region-specific.

If there's anything else related to the app or streaming issues you'd like help with, feel free to ask! Are you satisfied with this explanation?
