On any Panasonic Toughbook you can rotate the screen as follows:
Hold down the "CTRL" and the "ALT" keys and while holding down
these two keys press the "UP Arrow" key and then release all
three keys. This will reset the screen so it is right side up instead
of upside down.

Good Luck and regards from:
Richard, Authorized Panasonic Canada Toughbook Dealer since 1989.

P.S. The arrow keys look like this: The up arrow is the one on the top

Does the power adapter get warm or is it cold? If it is cold after several hours of being plugged in, the adapter has failed. If the transformer blocks are warming, the wires between the adapter block and the base or the connectors are bad. You can try to get a replacement.

For the KX-TGC420E, the base AC power transformer is part PNLV226E0X; the AC adapter for the handset chargers use part PNLC1074ZB. However, I can't find either of these online.

I found the manual from Panasonic suppport: . You do need accept the Panasonic terms of use to download the PDF.

I hope this helps.

If it's that delicate, but you still want to keep it, you could try changing-out the mains fuse in the unit for a really, really low amps one.
You might be getting a power-surge as the power goes off, or as it comes back on. A very low fuse, might blow on the surge, which will leave you needing to replace the fuse, but not the capacitors.?
Best of luck.

Just reboot it. If that doesn't work, do a System Restore.

Get it from the guy in this video

Panasonic TH 42PX70 St By Light Flashes 10 Times

This is a TH set, however rather than the power supply, it is something else.

The thing we find in Fixya is that people do what you do and blindly swap pieces out. The course to become a television engineer is 2 years full time.

There are probably too many routers on the same channel in your area; very common problem. Too many routers on the same channel in close proximity causes interference and will cause wireless devices to intermittently disconnect from the wifi. To figure out if you have this problem, download wifi analyzer from the app store. Run it and you will see how many router signals are in your area and how many router signals are on the same channel. Xfinity uses channels 1, 6, and 11 for the 2.4ghz and these hotspots are everywhere! To fix this, log into your router and pick a channel that no one is using. I always set mine to channel 8 or 3.
