Hello and thank you for using JustAnswer.

One of the factory resets is to hold the power switch for 3 seconds. Let me know if this does not work.

yes i did that. no response
Expert:  AnswermanRob replied 3 years ago.
I was afraid of that. The next reset will totally reset the unit.

Press power on the unit to turn off the unit.
Press and hold the "fast forward" button and press POWER and the OPEN/CLOSE button on the unit at the same time for more than 5 seconds until “PLEASE WAIT” is displayed on the unit.

The unit should turn on and off.

Keep your fingers crossed.

i have the manual, I tried that too. unit stays off.

checked power and power cord OK. it seem the firmware is screwed and it requires a manual reset button as the processor does not seem to be reading the user buttons.

thanks

I'm out of solutions. I'll opt out and allow other experts to comment if they have a solution. You may be forced to contact Panasonic.

Good luck!
