I have Roshan tv,my remote is not working,fell,n,damage.model Hh 21scp

If your Roshan TV is showing a black screen, there could be a few different causes for this issue. Here are some steps you can take to troubleshoot the problem:

Check the connections: Make sure that all the cables are connected securely and properly to the TV and the devices connected to it. Check the power cable as well and ensure that it's plugged in and switched on.
Check the input source: Ensure that you have selected the correct input source on your TV for the device you are trying to watch. Use your TV remote to change the input source and see if that resolves the issue.
Check for updates: Check for any available updates for your TV firmware or software. This can usually be done in the TV settings menu.
Restart the TV: Turn off the TV and unplug it from the power source for a few minutes. Then, plug it back in and turn it on again.
Contact customer support: If none of the above steps work, contact the customer support for Roshan TV or consult with a professional technician to diagnose and repair the issue.

Under your settings menu on your TV there should be an option for allowing a connection to devices casting to the TV. Ensure your TV is capable of this first. If you provide the model number of the Roshan I can be of more help.

After you've verified that your TV is connected to the same Wifi network as your Samsung phone, swipe down from the top of your Samsung, swipe down again to bring up the device controls. Scroll right until you find the icon titled "Smart View". Click on it and it will scan your network for compatible devices to cast your phone to for mirroring or playback. Your Roshan, if configured correctly, should be displayed in this menu.

You can reset and eliminate the lock on some televisions without the remote, using a few tactics. Hold the power button for five seconds. The television will automatically restart.

Given the apparent lack of available info about that make and the likely relatively small price difference at that size, (guessing it's cheap?) my gut feeling would be to avoid and go for a better supported brand.
