Sharp Aquos LC-60LE636E - bad channel numbering

I found bad channel numbering after digital service found (DVB-T).
Expected channel numbering: 1, 2, 3 ...
But TV gives numbering: 4, 5, 6 ...

If I press channel 1, error occures:

Can't find this channel.
[E204]
Check the channel number on EPG, etc.

Cler channels and start again (=run Auto instalation) didn't help.
No new firmware existing.

Main version: 300E1206141
Monitor version: M000110
