What does the blue bar on the right upper corner flashing mean? On a dish network box

SOURCE: Green box keeps popping up in upper right corner

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.

There is no factory option to stop the box from poping up every time the signal changes, which is what is happening. It has something to do with signal strength or the fact that your cable box is not set up for HD. Call your cable company to get a tech out to check your signal and set up your cable box because they do not come pre-set with HD defaults.

Had the same problems. Rebooted the box and the 2 was gone. Hope this works.

Yes, I do. It needs a new light engine. Very costly repair. However, Sony has extended the warranty on many of these LED projector sets. You need to call a local Sony authorized service center and see if your model is covered. Otherwise this repair could run over a thousand bucks.
