The rear control buttons on the screen are unresponsive and the menu does not appear

Question

Accepted Answer

Checks to Perform

You have already completed the essential steps (restarting and checking the cables). Here are the next actions:

1. Complete Restart (Hard Reset)

The TH-65SQ1WA contains advanced software that may require a deeper restart:

Completely unplug the power cable from the wall outlet
Wait at least 5 to 10 seconds (the screen must be completely off)
Reconnect the power cable
Allow the screen to fully initialize (about 1-2 minutes)

Then test the rear buttons to see if the menu reappears.

2. Check the Indicator Lights

Observe the power indicator on the screen:

A steady green light indicates normal operation
A flashing red light indicates a hardware failure requiring professional repair

3. In Case of Persistent Malfunction

If after this complete reset the buttons remain inoperable and the menu still does not appear, it is likely a hardware failure (control board or internal connection cable). In this case, contact an authorized Panasonic service center for diagnosis and repair.
