SOURCE: Loss Sync
According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective.
Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again).
It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box.
Hopefully, this will clear the problem
if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you.
thanks.

We had the same issue. Contacted Time Warner, and were instructed to reset the digital receiver by unplugging the power supply from the back of the receiver for at least 30 seconds. This will force the receiver to reset.
Fixed it for us. Big sigh of relief!
SOURCE: The channel information/display won't stop popping up every few seconds.
What you all need to do is get away from a coax cable connection. If you have a cable box, or satellite box, take the coax cable off and use red, white, n yellow rca composite cables to connect your recievers to the tv. if you dont have a cable box, either get one, or get a converter box and use a tuner outside of the tuner within the unit. The tuners in those tv's are built to show you when you experience signal fluctation(which is normal with a coax cable) and thats why the box keeps popping up on its own. good louck to you all with this problem
SOURCE: Panasonic viera has flashing channel info in upper left corner
I had this exact same issue just yesterday. Channel info would flash
intermittently. While set was in this mode, could not enter menu,
change channels, etc. from remote or front panel controls. Similar to tjh492, I thought it might be an
overheating issue. But unplugging the Viera and waiting for set to cool
made no difference.
I then remembered that this issue popped up the instance I surfed to a
particular channel (FWIW, 26-3 "Me Too" on Comcast here in Aurora,
Illinois, USA). I had a hunch that there might be an issue with the
signal on the channel that prevented the Viera from properly syncing,
so I decided to unplug the antenna cable. Once I did that, the channel info
displayed steady. I was then able to change channels (of course screen
was blank as antenna cable was unplugged) and enter the Viera menu. I
immediately went to channel set-up and manually removed channel 26-3
from the channel list. After reconnecting cable, Viera was back to
normal. Since I'm not a big fan of "Me Too", problem solved :)
Not sure why a digital channel sync issue would effectively make the
Viera remote and front panel controls inoperable. Pure speculation, but it could
be that the Viera microprocessor was overloaded trying to sync to channel and this prevented any interrupts from remote or front panel
controls.
