For me, I'd be looking at the product manual to see if any resets noted there can pull it out of the fire.
I have a Panasonic TX-32LXD700 TV . With no prompting the screen displayed "Self Check Complete" with a list of figures. When I switched the TV off by remote and then on again it started checking digital and analogue settings. Then the display changed to a password page, inviting me to insert a new password. With the remote I attempted to enter a password, but the screen reverted to the self check complete page. This loop continues, and I cannot do anything else with the TV.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
