We had a power outage today for several hours. When power was restored, the Panasonic unit woke up again, however, nothing shows up on the TV screen. I can't see any menu's, channels, nothing but blue screen. I tried to reset the default settings, but I'm not even sure if I've done that.
Is there any way you can reset the AV channel on a TV?

Unplug the unit for 24-hours. I know, it should not take that long, but in this case I tried shorter periods WITHOUT success!
Just before plugging in unit depress and hold POWER button. You are supposed to hold it for 30-seconds after plugging in, but in my case I did it for 60-seconds. This results in a MASTER RESET that clears all errors, resets interlocks, etc. I could not get past a DVD failure problem, but when I discovered this process everything worked fine!!
The Panasonic DMR-EH50 can be reset like it was brand new. I assume the DMR-EH55 can be also. The up and down channel buttons are located on the front of the unit behind the small door in the center. With the unit on press and hold these two buttons for atleast 10 seconds. This will restore the unit like it was new and you will need to go thru set up procedure. The above action will put the unit in the off position. When you turn it on it will guide you thru the set up procedure. Once this is complete you can press the setup button and manually set the clock, however, the unit will need to be shut down for 24 hours to allow the tv stations line-up to be restored.
There might be a TV Guide issue located in your area, since the transition to digital, TV Guide have been updating there broadcast frequency which is know been done by CBS. Have unit reset by holding down channel up and down button for 15 second on the unit itself until 12 flashes on display, then power on unit and setup TV Guide, then have unit off for 24 hours especially between 11pm to 6am for listing. If issue still exist contact Panasonic to have issue send to TV Guide.
First, check whether it is the fuse in the home wiring that is out. You should plug something else into the outlet to see if the outlet is still functioning.
Some electronic equipment has a reset switch (fuse) on the back panel. Others have a special sequence of buttons on the panel that will act as a reset. Check your user manual to see whether your unit has such a switch or reset sequence.
could be a ratings problem. Perform a reset by holding down your channel up and channel down buttons on the unit itself simultaneously until it shuts off. Wait a few seconds and turn it back on. Give it a try. Good Luck - Tamara
Hi there, this is what Panasonic say....
The "U99" error code signifies a "general communications failure." It is not associated with one specific problem. It can be related to the version of firmware your DVD recorder is currently using and it has been associated with the TV Guide on screen guide.
If your unit displays U99, turn the power off-unplug the unit for 5 minutes, and reconnect the power.
Sounds faulty to me, I'd take it back to the store and get a
replacement. However, I guess you want that DVD out first? I'm not sure
this will work because the units logic board is mostly likely faulty and will
prevent the DVD transport from opening. Unplug the unit and press the
eject button, keeping it pressed plug the unit back in. If the unit
does not come on then press the power button too. If the unit starts to
open release the button immediately. It's unlikely to eject, but you might get lucky.
