Why does any button that I touch reboot the tv.

Push any button on the remote, the tv reboots and gives no signal response. Push the power button on the side of the TV, TV will not turn off, will reboot. Push input button on TV, TV reboots. Anything that you touch, TV reboots and gives “No Signal” response. Will not allow you to go any further to repair. Have done everything except for taking it apart. Sony Bravia KDL40R510C
