The Sony Classic channels (and some of their others) are on Local multiplexes, see Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.
The Local multiplex at Rowridge is on UHF C37 and your aerial needs to be horizontal polarisation. The Local multiplex is not transmitted in vertical polarisation from Rowridge (neither is COM7).
It will depend on your location as to whether you can receive the multiplex. Try a manual tune on C37, if the signal is weak, an automatic tune may not find it.
If your provide a full postcode, we can look at the predicted reception in your locale.

Have your signals now returned?
If not, check all your connections etc. and that your aerial is still intact and pointing in the correct direction.
There is currently some variable "Tropospheric Ducting" around due to current weather conditions which is affecting reception for some viewers. You might be getting interference from the Crystal Palace transmitter.
Have a look in your TV's tuning section and look for the signal strength and quality figures and compare each of the multiuplexes which may help identify any issues.

My elderly aunt in Emsworth has lost all the channels transmitting on channel 27 on her human box. They were fine last week but now say channel scrambled or unavailable. Her TV is fine as are all the other multiplexes on the humax. Any ideas?

According to a Freeview report I've just seen, there is apparently Planned Engineering at Rowridge although it's not on the main list!!
This is the most likely cause of the channel loss. These sort of things don't normally last for very long, have her channels returned?

With the Planned Engineering, any one or several multiplexes could be affected at any time depending on the nature of the work being done. There could be service interruptions or reduced power (the latter possibly causing picture or sound break-up).
You should NEVER retune when this sort of work is going on as it can usually end up just clearing the correct tuning, or even getting tuned to some more remote transmitter whose signals will not be stable.
If you do so, you'll end up have to retune again when the signals are back to normal, and as you can't be certain when that might be, you may have to try several times. If necessary, manual tuning on the affected multiplex(es) would be better than a full auto-retune as you don't run the risk of messing up those multiplexes that are ok.

Used to get all Freeview channels from Rowridge where the aerial is pointed. For last 18 months or so, signal is from Findon. from which we get only Freeview Light. This is true of a corridor about two miles wide acress Bilsham, Middleton, Felpham, Bognor. Half a mile south of me get Rowridge, a mile north they get Rowridge. Why do I NOW only get the Freeview Light from Findon. This certainly affects several thousand people in the area all of whom seem to have aerials pointed at Rowridge from whence they used to recieve the signal.
Can you explain what happened to necessitate the change?
