I have not seen this before nor have I seen anyone post about it. This morning on the SD channels, they were all very blurry. Looked like a convergence problem. I checked my ota's and the TV was fine. Checking the 811 HD channels, they were fine but going back to the SD channels, they were still very bad. Well, did the "weekly reboot" and it cleared it up. Still have the P2.82 upgrade. Anyone else seen this before?
