Looks like an old Sony TV(?) and the H9S might have its settings on a high res. Press the 'V.Mode' button on the remote, see if that cycles through the resolutions and then picks it up. If you get the box on a low res - the TV might then pick it up.
If that fails, plug the H9S back into the TV is does work on and then set it to the lowest resolution then try it on the TV pictured.
