I have the same problem. It seems we have to reset the counter. This reset must be done via the beamer itself and not via remote control, since lamp is not working...

With the power on and the lamp off, hold the input button down on the projector then press and hold the power button for 5 seconds

To me itcsounds like ypu have a 1080p signal, 1080i is what it accepts. The 1080p signal will only show up on half the screen. Switch blue ray player to 720p or 1080i output.

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

Check the Panel ribbon cables and re install

Check Panasonic's website service department for the cost and availability on the replacement fan.

If you are handy with SMT rework it might be possible to fix this problem. The heat spreaders on the LCD drivers are insufficient to cool the chips and they will get hot enough to reflow the solder and cause a short on some of the pins. I think it most often happens after bulb replacement since bulbs near their end of life are dimmed and run cooler. After replacing the bulb the bit of extra heat is all that is needed to push them over the edge.

The problem also seems to be most prevalent on the green IC since it shares a heatsink with red and has a smaller area to dissapate the heat into.

If you pull the heatsink you will probably be able to see the short with careful inspection. The pitch is very small - 0.6mm but I was able to wick, clean, and reflow one side of my green IC and the problem went away.

I am planning on adding some additional aluminum stock to the heat spreaders with some thermal adhesive to give the chips more cooling.

By the way the very common rattle noise in these projectors is not a fan but the auto iris. You can unplug the iris servo from the mainboard and disable the auto iris in the menu to work around the problem or you can replace the iris servo for about $75, again, if you are handy with that sort of thing.

Something is catching on the fan blades. Possibly a screw or piece of plastic has come loose and is connecting with the fan blades when you switch it on. When the projector has been cool for a few hours remove the lamp and gently shake the unit to dislodge whatever is catching on the fan.
