I have den-b 5500 (55 Inch) TV with board: TP.HV553.PC821B firmware version: 20191223_193742, Android 7, and panel is T550QVN05.7. It is hanging on wisdom share logo and sometimes pop ups coming about some applications or services has stopped. Can I have new firmware to upgrade this board. If you can send me a link to download firmware which compatible to this I really appreciate.
