![]() Probably due to bad weather or a poor dish installation for new customers or a the dstv dish alignment with the dstv satelite has changed. ➢ Dstv not scanning : The most basic reason as to why your dstv is not scanning is because the dstv dish signal is so poor at the time. ➢ Message on screen – no signal or searching for signal at MHz/Scan ➢ Four horizontal lines flashing on the decoder (searching for signal) Since the repair (I changed all the caps for Panasonics) it has been rock solid reliable.If you have any of the problems listed below, see below the specific clues that you need to know to establish the problem: The PSU was loaded with CapXon capacitors, but as with the satellite boxes the rest of the build quality is very good for domestic kit. I have recently rebuilt the PSU in a Thomson DTi 6300 Top Up TV box to use as a FreeView PVR for my parents (I got it for £20.00 on eBay!). This is a pity for Thomson as it lead to their very poor reputation. The PSUs were built apparently by Samsung but to Thomson's spec and were rubbish. Mine has and continues to be excellent (albeit a bit slow compared to Today's boxes). I regularly state on here that PSU & HDD aside the Thomson Sky HD box is a good piece of kit. The poor quality capacitor even occurs very frequently on at least one model of Technomate as well - the TM9100. The rest of the build quality of the Thomsons is very good and very little esle causes problems except the HDD. Thomson actually bought in the PSUs ready made from Samsung. Obviously there are cheaper sources of kits on eBay, but do you want to fit it and forget it or install a cheap kit and repair again in 12 months or so (there are even worse brands than CapXon out there so beware). I have not ordered one but I would be surprised if the kit did not feature Panasonic parts as Satcure do not sell cheap rubbish. ![]() Satcure supply a repair kit for the Foxsat which is £8.95 + VAT & P&P. Thomson were well known as a bunch of cheapskates who would use any old cheap crap in their PSUs as long as most of them lasted 13 months.Īny decent repairer (such as the excellent Michael Dranfield mentioned above) would replace these with Panasonic capacitors (preferably FC grade) as these are far higher quality and should never fail again. They are a cheap rubbish brand and I am surprised Humax went down that route as they (Humax) have a good reputation for build quality. The photos I linked to above are all of failed CapXon capacitors. Thomson used CapXons in the original Sky+ HD boxes and these have all pretty much either died or been repaired by now. CapXon is a cheap poor brand and premature failure is very common. If Humax used CapXon capacitors in the Foxsat PSU I am not surprised they have failed. Make sure you do all of this with the unit unplugged and don't go prodding around the internals with your fingers or a screwdriver as some capacitors can hold a large charge for quite a while after being unpluged). If you are still unsure, take some clear digital pictures and upload them to a photo sharing site like flickr and one of us will have a look for you. If you are not sure what to look for, follow the links on this post from the Sky HD forum for pictures of failed capacitors. Take a look at the capacitors on the board (they look like litttle barrels), they should all have totally flat tops, any that are domed, bulging (no matter how slight) or worse have poped open and have gunk leaking out of them will have failed and need replacing. The Power Supply Unit (PSU) will be the board that has the mains cable coming out of it or the two pin mains input socket attached to it (I do not have a Foxsat so do not know the layout but it will be one of these). Chandleo, you could have a look at the internal workings of your Humax and make a diagnosis yourself.
