SOURCE: NO DTV CHANNELS

There may be an input button on the remote, or on the TV, that allows you to switch from the standard ATSC tuner to the DTV tuner.

Let me know if you can't find it and I will dig for an owner manual. But the above should allow you to switch tuners and input sources.

SOURCE: HAVE GOT A SWISSTEC 15 INCH TV BUILT IN FREEVIEW,

The model number would usually be on the back of the TV but in this case it's immaterial as Swisstec appear to have had a very brief existence. Their website no longer works (skymediamanufacturing.com, no connection to Sky satellite tv) and the few products which have their brand name on all seem to be at outlets like ALDI and Makro which often specialise in clearance lines and bankrupt stock.

First, check that your missing channels haven't been shifted to 801, 802 etc. This is happening with some equipment and it's just how some slightly incompatible equipment handles the retune.

What you have said about your aerial system does not eliminate the possibility of an aerial fault; as you're running multiple items off one aerial I'd fully expect it to be a high gain aerial, but this does not necessarily mean that it's a wide band aerial. In addition, each time the signal from a single aerial is split there is typically up to a 10dB loss (around 60% each time). Regular analogue reception equipment can cope with this far better than Freeview receivers as the analogue signals are vastly more powerful than the digital ones. One of the most important UK transmitters puts out a 100kW (i.e. 100 000W) analogue signal along with an 800W Freeview one making the analogue signal 125x stronger at the transmitter and far weaker further away.

Realistically, you have limited options. Most Freeview receivers have an onscreen menu in the digital tuner which has a signal strength and quality meter for each channel. If most of the channels have a middling signal with good quality then your reception is most likely ok so look at the aerial cable at the back of the set to see how long the plug into the back of the tv is. If it's longer than about 2cm then it probably has an in-line suppressor fitted onto the end of the plug. Usually there's a marking of either 6dB or 10dB on the suppressor. Remove any suppressor and try retuning.

If that didn't work then check as much of your aerial system as possible paying special attention to the plugs and splitters. No plug should be showing any bare wire, and the external screening braids must not be touching the internal signal wire. You'll probably have to undo each plug to check for this and remake any shoddy work. If you have aerial splitters which are the push together variety then check the connections are tight. Also consider replacing them with the screw threaded F-terminal splitters which all professional installers use. These cost very little more than the useless things sold in most DIY stores and general retail outlets but hugely reduce signal losses. I've posted an online address of a supplier at the end of my post, but you can also get them from your local Maplin store usually at extra cost.

If you have an amplified aerial then try disconnecting the amplifier. These are often inappropriately fitted and cause digital signal meters to show the confusing message of a strong signal with poor quality. A good quality weak signal can be successfully amplified but a poor quality signal requires a better aerial installation.

If you have eliminated all doubt regarding your aerial then the fault is most likely with the receiver itself. The official advice is to try retuning but you've almost certainly done that. There is a list of equipment known to have problems with the retune (see second web address) but it's not comprehensive and misses out minor brands like Swisstec. Clearly you cannot contact Swisstec and they are in no position to rectify the problem themselves any more. Under these circumstances your only remaining option is to buy a new external receiver from around £20 and connect it to your tv as if it never had an internal receiver.

Note that the UK Sale of Goods Act was recently amended to allow purchasers up to six years protection against goods which are not of "satisfactory quality" (replacing the earlier term "merchantable quality"). You've had your tv for eighteen months and the tv itself still works, but as a super-budget unknown brand it's doubtful that you could press your rights regarding the failed Freeview receiver.

Sorry this is not the easy fix you were hoping for but I hope that it's been of some assistance.

These will have been rolcated to a different channel number. You can select the programme guide & scroll through all the channels until you find thier new location number, then you could either take note of these new numbers or go into the set up menu where you can re-arrange the channel numbers back to 4/5 etc or set them on your favourites listings

On my Techwood it as built in freeview but every other channel is right except bbc1 and bbc2 both channels say bbc wales,How do i get them back to bbc1 and bbc2 please PLEASE HELP.THANK YOU.


What you need to do is retune the TV, but when it is finished look at the regional settings. Or if the regional option is available before retuning, retune selecting your area so then you get normal BBC channels. It's likely that at the moment the channels for BBC are located at the very top end of the channel list say? - channel 800+.

You are clearly picking up signals from many transmitters. With regional settings you can change it to the area you live in.
But you will have to take into account how good your aerial is. Otherwise the signal quality will not be good on same transmitters. So the set may only suggest those with the best quality signals.
ITV stations might also change.
When done it will move the channels you mention to the top end of the guide, to 800+.

Note many HD channels have no regional options. For example here in Yorkshire we only get ITV Granada and not Yorkshire TV on the HD channel for ITV1. And BBC1HD does not show any programmes when local news comes on.

My humax won't;t record bbc channels. I have tried retuning the tv.


This could be too much signal thanks to the Freeview retunes going on. Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range. The signals for BBC and ITV are among the strongest ones broadcast. If they are now at a point on the aerial's range where they are too strong for the TV then the tuner will over-saturate. The result is the same as no signal.


Have a look online for a Variable Signal Attenuator. It's a device that can be added to a aerial signal cable just before it goes in to the tuner. The adjuster allows the signal level to be reduced. Watch the TV's signal quality and signal level displays if it has them. As signal level (power) reduces you'll actually see signal quality increase. If you go too far then quality will start to go down again. The optimum point is where quality is highest.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

Cannot tune all digital cahnnels on Sharp aquos


Start by doing a factory settings/ defaults on the Sharp rather than a normal automatic retune.This should then be ok. You need to empty the existing presets first so it will find the new type of signal BBC is now using.
If still not working for BBC1 +2 then look at whether you have too much aerial signal strength. (ie a booster/splitter that you could bypass)
