There is nothing, just static, and an error message saying weak signal.
The noise level from electrical interference is higher on VHF-High, real channels 7-13, than on UHF. It is possible that it has increased lately. Is the coax shield grounded?

The coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
