    My bags have been packed for years, just in case. JK. Seriously, I think the electronics do a scan every so often and the green box is a visual output showing everything is in order. The only thing that is abnormal with my TV (Olevia) , is that now it seems to overheat because it will shut down and if I try to start it up within seconds, it won't turn on. But if I wait for about 10 seconds, it will start up fine. I don't think it has anything to do with the green light because the green light always came on from when it was new. On the other hand, my aluminum cone hat is due for some service.

My tv does the same thing with the small rectangle green light. It will flash for less than a second. I think it is when they are taking a photo of my living room, like when you can take a photo with your xbox kinetic when you jump. Might be aliens. Thanks for any help. getameapizza

    My Samsung tv does it too but it has no camera so it can't be taking a photo. Sometimes the bar is green, sometimes blue, and sometimes purple.

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.

SOURCE: Small black box in upper left corner of Sony TV - need to remove

I had a similar problem on my Toshiba Regza but trying my fix couldn't hurt. I use a satellite dish for TV (if you do the same this might work)... I turned off my receiver, took the programming card out, cleaned it with my shirt (especially the part that looks like a computer chip), put it back in the receiver, turned it back on and when everything reinitialized the black rectangle was gone.

Hope this helps.
