J G Lobb:

Now that is a tricky one!
I trust you haven't retuned whilst you hadno signal, if so, this may have cleared your correct tuning, so try a MANUAL tune ofTorosay's UHFchannels as listed at the very top of this page.
Other than that, it's possible there is unlistedEngineering, but feel free to proceed with any checks you want.

Firstly check theaerial is intact and still pointing correctly but do a visual check of thecable en route to see if there is any obvious damage. Check the aerial and other connections whilst you are there for corrosion etc.

Do you have a (digital ideally) voltmeter so that you can check that 12v supply.
First unplug the feed to themasthead and check that 12v is present on theoutput of the distribution amp. If it's not, there's the problem.

Even if it's there, the distribution part of the amp may have failed but checking that will either be by taking it somewhere where there is a signal (a friend's) and connecting it to their aerial output and see if the outputs provide signal to their TV. Alternatively by substitution, but that means buying or borrowing another so probably best left as a last resort, or of course getting it professionally checked! Probably best to check the rest of the system first.

If 12v is ok, then check if it is arriving at the masthead amp,

If it's arriving at the masthead, and all other checks are ok, the masthead itself may have failed.
In your situation I cannot think of anything other than get it professionally checked, but read on first.

If it's not arriving at the masthead, there could be a break in the coax cable somewhere. Finding that may be difficult. You'll probably need someone to help and an ohm-meter or continuity tester.
Disconnect the cable at both ends and then short together one end and put the ohm-meter or continuity tester on the other, then work your way along the cable flexing it slightly to see if you can find a break where your friend sees a reading which wasn't there to start.

If everything else checked out ok, then if you still have no signal you ideally need a signal strength meter you can connect direct to the aerial so see what you are receiving. There are currently no reported faults that I can find, and as previously mentioned thetransmitter is not currently listed for Planned Engineering but there could still be work in progress in which case i would expect signals to retune later in the day.

I don't know if anyone else has any bright ideas about checks that I may not have thought of.

Ian Forsyth:Torosay transmitter currently has plannedengineering works listed, which may require thesignal strength to be reduced or switched off for periods of time whilst the works are taking place. If you provide a full postcode we can see what the predicted signal strength is at your location.

Duncan Martin:

I can't currently find any faults listed forTorosay and thetransmitter isn't on the list for PlannedEngineering at this time.
Your predictedreception for ArqA and ArqB isn't quite as good as the others. What %Quality figures are you getting for each of the other multiplexes?

Do check you are correctly tuned (use Manual Tuning) for each of Torosay's UHFchannels which are 28/25/22/23/26/30.

There's currently some weather related Tropospheric Ducting which may be briefly disrupting reception in some areas. There's currently a BBC Warning
High pressure could affect TV & Radio services across parts of the UK - 19th July | Help receiving TV and radio

If you are correctly tuned to UHF channels 26 & 30 for the ArqA & ArqB multiplexes and your signals haven't returned, there's another likely possibility -
You should have received a postcard from Restore TV. You may be gettinginterference from any new/upgraded phone masts now operating in the700MHz band.
Seehttps://restoretv.uk/post…ure/ and enter your postcode. There are at least two mobile masts close to you.

Contact Restore TV 0808-1313-800 for a Free Filter. IF you have amasthead pre-amp you should advise them of that as they will have to send an Engineer (Free of charge) to fit a filter on the mast before the pre-amp. A Filter have to be fitted BEFORE (on the input to) and Amp or Amp/splitter.
