I recently replaced the UPC Horizon box with the new UPC TV box. Since then, the wireless switchbox (WFHD kit WDP02) does not switch off. With the Horizon box, the switchbox was switched to standby mode during TV operation. Since I switched to the new UPC TV box, the switchbox WFHD-Kit WDP02 does not switch off or cannot be switched off. It is not due to the switchbox, as the error does not appear when I reconnect the Horizon box. Can anyone help me?
