Picture is perfect in between the periods of pixellation & signal loss which last approx. 5 - 10 secs. Problem seems to be present no matter what time of day (or night!)Willing to try masthead amp but multiplex signal strength & quality seems to be strong enough apart from during periods of interference.
jb38: Neighbour across the road does not experience similar problems. Have tried alternative Philips TV, from a bedroom, using same aerial & mains sockets for a couple of hours and some interference experienced but not at the same frequency as the main set- about the same level experienced when connected to its usual log periodic aerial, mounted in the loft & tuned to Belmont (this appeared to be Inversion interference, since only appears during clear air conditions) Main TV not tuned to Belmont by installation engineer due to large horse chestnut tree in sight line from its chimney mounting. I fitted the log periodic aerial. Hope this provides some further detail of problem. Will try radio test tomorrow, if I can find our old multiband transistor radio. Thank you both for your interest & suggestions. What is perplexing me is "what has changed?" Picture quality & stability consistant until late Feb!

jb38: Sorry for not responding to your last reply before now but have been away over most of the Easter period. However the situation changed last Tuesday (3rd April)p.m, almost totally in synch' with the change in weather conditions. Away from home Wednesday a.m to Sunday p.m but on return no interference problems experienced thus far. So situation OK for now. If interference returns what is the best longer term solution - different aerial, masthead amp or other? By the way, carried out 'radio test' but did not reveal any 'mains' problem. Many thanks for your informative responses.

Hello, Looking for help to solve a persistent interference problem on my Samsung D6530 set. Location is PE10 0AF. Aerial is 28 element DMX type aerial tuned to Waltham transmitter. Problem started about 6 weeks ago and is characterised by pixellation & loss of signal approx every 6.5 minutes. When problem is not present signal strength & bit error levels are 90% & 0 on Channels 29; 61 & 54: 74% & 0 on Channels 56 & 57 and 42% & <180 on the HD Channel-58. I have repeatedly auto-retuned all channels & three days ago manually tuned all six of the Waltham multiplexs, without any improvement to the problem.
I have also checked for any internal sources of electrical interference (c/h boiler, fridge, transformers etc) and still could not obtain any improvement. Any ideas on where to go next would be greatly appreciated?
