Heather: If you have a booster then maybe it needs turning down; the thinking here that it might have been installed in an effort to increase the signal level due to the tree.
Where a signal of too high a level is being received then it can appear as if the problem were the opposite which is too little a signal.

Two hours ago (see my posting above) UK Power Networks' map showed no power outages in and around Aldeburgh. Now it shows one which could affect the transmitting station:
UK Power Networks - Current Network Incidents
INCIDENT REF: INCD-758426-H
INCIDENT RAISED: 04-JAN-2014 18:00:51
ESTIMATED RESTORATION TIME: 05-JAN-2014 00:00
POTENTIALLY AFFECTED POSTCODE SECTORS: IP15 5,IP16 4
Janet Harvey: I don't know about you not having a TV signal since this morning as the power outage occurred at 18:00, which was shortly before a flood of messages to this website.

Mike B: The main ones and larger relays do. Some have two incoming power supplies.
See here for former NGW stations:

Aldeburgh has a single power feed and no generator.

Jill: With manual tuning you need to scan UHF channel 33 (570MHz). If there is an option for DVB-T or DVB-T2 then select the latter. Standard definition transmissions use DVB-T; high definition ones use the later DVB-T2.
If you are using a communal aerial system such as are often provided in a block of flats then you will may need to contact the party responsible so as to get an engineer to enable reception of C33.
The transmission power of C33 is lower than the others. Consequently some users will not be able to receive it reliably.

Jill: Yes, try the booster.
The signal you're trying to receive is 81.3kW (according to Digital UK), so it is in now way "low". The pre-switchover digital signals were at 8kW from Sutton Coldfield.
Your difficulty is likely to be caused by the fact that you don't have line-of-sight to the transmitter. If you were to go higher above the ground, where you could see the transmitter above the obsticles, then you would have excellent reception.
What I suggest you do is go to the manual tuning screen and enter/select C33 but do not press the button to scan the channel, as most receivers act as a signal meter. From there determine whether there is any strength and quality to the signal. See whether adding the booster helps.
The thing with digital reception is that there is strength and quality. A receiver requires the strength to be above a particular level (threshold) in order to resolve a picture (assuming quality is good). So if you have a good quality signal that isn't high enough you can use the booster to make it bigger. If it's a poor quality signal that is too low, adding the booster will make it into a bigger poor quality signal. Due to the fact that you don't have line-of-sight you could potentially find that the quality isn't there.

TT: This would seem doubtful, although you can always check with at800:
Contact at800 / DMSL | General Enquiries | at800
Looking at the coverage checkers of O2, Vodafone and Three, they provide no 4G service in Cwmbran. EE does, however it was allowed to use some of its 1,800MHz allocation (which is used for 2G) so we don't know whether it is at 800MHz which is that which can cause issues with TV reception.

Lena: It appears that the Aldeburgh transmitter was off the air from approximately 18:00 to midnight on Saturday, possibly owing to a power cut to the site.
If you performed a retune during that period then you will have untuned it which means you will need to retune. If you did nothing then it would have restored itself when the transmitter was turned on again.

Angela Yusuf: If the postcode you supplied is yours or near to you then you are much more likely to be being served by the transmitter on Whitehawk Hill, adjacent to the Racecourse. Newhaven transmitter is on about the same bearing but serves Newhaven and the surrounding area.
The first thing to do is check that your TV is indeed tuned to Whitehawk, and not one of the other transmitters, as there are quite a few you might have picked up.
Bring up the signal strength screen on each of the following and observe the UHF channel tuned:
PSB1 | BBC One = 60
PSB2 | ITV = 53
PSB3 | BBC One HD = 51
COM4 | ITV3 = 57
COM5 | Pick = 56
COM6 | 4Music = 48

John Williams: I reply to your posting as a courtesy to others, in order to prevent them from wasting their time. You have posted this question several times and each time responses have been posted which you have not even bothered to acknowledge:
Ten more HD channels on two new Freeview HD multiplexes on air from 2014-18 | Freeview news | ukfree.tv - 11 years of independent, free digital TV advice
Please stop wasting our time by asking the same question and failing to give any acknowledgement.

Radio & TV Investigation (which reports BBC engineering and faults) doesn't report an issue with the Aldeburgh transmitter.
UK Power Networks shows power cuts in the area and none are shown in the Aldeburgh area:
