The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

My current 15inch flat screen tv in the kitchen went wrong on Friday 24th January so rather than buying another I decided to dust off an old but perfectly working 14inch 4:3 Phillips set, I nipped to Tesco and brought a set top box and connected everything up. After tuning everything in and adjusting the settings I then set the picture mode to 4:3 pan and scan, I had already noticed on a family members old 4:3 portable with set top box that channel 4 and its sister channels had black lines top and bottom during the broadcasts and the pan and scan feature did not work on these channels (all others channels were ok) never did find out what the problem was tho.

My set top box and 4:3 portable did exactly the same with channel 4 and its sister channels too regarding the black lines, however turning on the kitchen tv on Tuesday morning 28th I noticed that BBC One also had black bars top and bottom (no other BBC channels were affected) but when it got to lunchtime and the local Look East news came on the pan and scan setting worked fine and the black bars disappeared, then after the local news finished and the usual broadcast returned the black bars returned.

Were the BBC carrying out any tests on BBC One or has something changed in the signal, the black bars are the same size as those on channel 4 and its sister channels so could it be the same sort of thing, any thoughts or help would be much appreciated.

It appears the engineering work at Sudbury is finished. We've retuned our telly, twice, but it's no better than it was during the work. Is anyone else still having problems?

Well whatever was going on with BBC One it appears to have only lasted a day, turned the telly on Thursday morning (30th) and picture has no black bars, gave it till the end of the weekend before posting just in case something was still not right.

Mind you channel 4 and its sister channels are still the same with the black bars on a 4:3 telly, guess I will never really know, its just one of those things that being the sort of person I am, makes me inquisitive.

JB, re your answer of 6 Jan, thanks. The aerial is pointed directly at udbury and if pointed elsewhere does not not work, therefore I cannot see defraction is relevant, and with analogue, although we got interference from the Dutch, we never lost the signal. I am at a high location with near 100% signal...............usually.

Just a buyer beware issue here. Our Panasonic Viera flatscreen full HD TV packed it in after 2 years 8 months with about 4000 hours on the clock. The set would normally be expected to do about 60,000 hours minimum. We had no luck with 6 year statutory rights as the supplier wanted a full technical spec as to what went wrong and why. No TV repairer could be that specific, despite agreeing that the set was, effectively, a write off and offering to speak to the supplier direct to that effect. A trawl of the internet appears to indicate that this problem is quite widespread. We have always found Panasonic to be a good and reliable brand in the past but this event, together with a highly temperamental Panasonic DVB recorder (well documented problems here as well), has put us off for good

Eddie Stacey: Panasonic actually has a pretty good reputation with the tech support people where I work. Like all the four big brands, you tend to get pretty good components, etc. However, you can get unlucky (one lady had 5 different TV's from 3 different manufacturers in eighteen months), and I quite understand if you've had a bad experience, you'd want a different brand. I'm surprised that the DVB is touchy (although the tuners are actually very sensitive), but again, these things happen.

What was the model and the actual problem? You said that the TV 'packed up' - was it the panel that went? If it did, then the TV is basically a writeoff. A lady came in a couple of weeks back, after her TV had developed a problem (which had been bought from Argos, not us). Our chap in tech support said that such a TV panel (if one could be sourced), would cost around £250. Considering the cost of a new TV, replacing the panel often makes no sense. Our TV's all come with a five year warrenty as standard, so if it wasn't worth repairing it, we'd just replace with the nearest model.

If you are about to buy another TV, its the end of the TV year (April is when the new models will start), so I'd get in quick, because stocks are really running down. LG, Samsung and Sony are all solid brands, I'd have no problem recommending them.

In reply to jb38 and MikeB, The TV was a Panasonic Viera TXL32E3B and the DVB recorder with the HAL like attitude is a DMR EX773EB. The 'flashing red light of death' signal from the TV when it expired was a single flash every three seconds which apparently indicates a fault that the TV cannot define. The engineer's diagnosis was a power supply panel failure and, in effect, concurred with MikeB's comments. As I stated before, this wasn't enough for the supplier. Needless to say we have stopped dealing with these people. We bought a new (Samsung) TV locally together with a five year warranty with their own local engineers. I hope this is of some use and thanks for the input.

Eddie stacey: Yes, the symptoms described would indicate a power supply module failure, what puzzles me is why the engineer who diagnosed the problem did not offer? to search around for a low cost second hand replacement PCB module, as one is even being currently advertised by a trade dismantler on e-bay for £35.00 + £4.00 P&P, the item in question being guaranteed for 30 days and which allows more than ample time for any faults that may exist in the board to show up, as buying new does not by any means always guarantee 100% reliability as some new components (particularly I.C's) can on the odd occasion fail after a few hours use.

My aerial was bashed about in the recent storms, and fell apart, so bought a new one, another WB High Gain, butr whilst up the ladder, and seeing the coverage charts showed both Bluebell Hill and Dover as alternate options, thought I'd give it a go, but no matter what direction I pointed the aerial it always picked up Sudbury, with not a sniiff of the others :-( (Post Code CO7 )
