Panasonic Plasma TH42PZ80U - Picture Reset Mode issue

Tried the unplugging thing, tried the Menu->Reset thing, tried the Vol- & OK thing (no buttons on the remote, nor under-tv menu functioned while holding Vol-) Not quite ready to try the fist-thru-the-screen thing... But I am getting ready to do the sell-it-to-an-unsuspecting-victim thing.

    Figured it out... The devil is in the details...

    When you unplug it for 5+ seconds, and plug it back in - DO NOT power up the TV with the tv button! You MUST use the Remote Control to turn it on. Did this, and works perfectly to reset out of Demo mode.

Don't do the latter, just do the take-it-to-the-tip thing.

Turn on the TV, red light stays on, picture goes blank after a second.


I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

Hi I have a Panasonic TH42PZ80U Plasma TV my problem is the led light blinks 8 times and we have no picture. I have unpluged the tv and waited a min. and plugged it back in and now picture.


There are a couple of possibilities; a power supply that will eventually fail completely, control circuitry that 'latched' up momentarily (this may never happen again then) or the 'firmware' is glitchy and lockups may happen again.
I would check Panasonic's website for possible firmware updates that have been made since your set was built.

Hi,

The Format Error will get displayed in the Walkman Player when the unit is Formatted using the format utility in windows explorer or with other internal malfunction.
To resolve the issue, try resetting and then perform the Formatting the In-built Memory option in the Walkman player.

If the issue persists, FORMAT the Walkman.
To FORMAT the Walkman, press and hold the MENU button in Stop mode until the SEARCH Menu appears.
Then, use the control Jog to select Advanced Menu and press > VOL to confirm.
Again, use the control jog to select FORMAT and press > VOL to confirm.
Now, select OK and press > VOL to confirm.
Formatting appears and starts formatting the Walkman.
When the Formatting complete, COMPLETE appears.
Press the > VOL button to return back to the playback screen.

After Formatting, download the MP3 File Manager Application to transfer the songs from the Computer to the Walkman.
This will resolve the issue.

Panasonic Viera keeps going into picture refresh mode. How can I stop this?


The tv is on "store" rather than "home" setting. If the message "going to refresh mode" keeps appearing every 5-10 minutes, do the following:

-Unplug TV from wall and leave it for about a minute.
-Plug TV back in and follow "initial setup instructions" (can be found on page 14 of manual).
You will be given the choice of "home" or "store" settings. Change it from "store" to "home".
-Done.
