I sometimes get that (V53) error on my premiere. After reading some threads that mentioned disabling tuners, I thought I would see if one of the other tuners would not display the message. But, when I switched to the other tuners a total of three of them were all tuned to the same channel (702) and each displayed the V53 error, though the picture and sound was fine. After changing the tuners to different channels I returned to the original tu er, still on 702, and The error message was gone! So, to anyone who has issues with this error message, switch to each of your tuners and change each tuner to a different channel to see if that clears the V53 error message!
