I have downloaded and installed the firmware update ( for my TV (37PFL9603D/10). Since then the image-quality is horrible. I already did a reset to factory-settings to no avail.

There seem to be "stairs" in the image, cannot describe it any better, but it looks just awful!

I am using a HD-Satellite-Receiver (TechniSat HD S2 Pro), which I also resetted, to make sure it is not the receiver (also used other receiver to double-check).

Anyone got an idea?

Thanks in advance,
