My Palsonic TV 40" says no signal. I have put a signal meter on the line, and signal strength is good. This happened as soon as I tried a auto retune to pick up more channels

garmin, it seems to me that your techs should be able to correct this problem by mounting the antenna in such a way as to place it in a fixed position where it could not be turned internally and cause damage to the unit with a force as small as hand tightening.

CB warning antenna on a cobra 29 lx camo


You may have blown out the output transistor in the CB. Can you still calibrate the swr meter? The K 30 isn't really a very good antenna. The Lil Will isn't either. I'd try a K-40 or a better model Wilson antenna.

When I try to retune TV to pick up new TV stations I get sound OK but a black screen with message invalid format.


Check stations MPEG format . Check if it is MPEG4 and check if TV can decode MPEG4 . A firmware update may be available on tv and may fix it but it has the risk of turning the tv into a brick if something goes wrong during a firmware update.
suggest contacting palsonic to see if firmware possible and which one to use.

Tmy tevion tv needs retuning every few days, what is the proplem?


First check the aerial's cable coaxial(coax) plug/s is/are ok. Poor signal strength can cause this problem - all bad coax connections drop signal strength.

The tv s autostore will not retune


i think in your TV...... design ..... is such that once channels are autostored it cannot be retuned ..... so you try this ...... it may work ......... disconnect tv antenna cable ( or local tv channels cable ) from your TV & then click autostoring (auto tunning ) ..... definitely it will scans (search for channels ) ..... but since no cable is connected no channels will get stored ...... but previously autostored channels will get removed ...... so now again connect your antenna cable or local tv cable & then click autostore ...... it will scan for channels .... like this you can retune ....... but remember again you may get same quality of picture which you got earlier ..... if you want better quality of picture you have to use signal amplifier (increases cables signal's strength - then picture quality improves ) .....

I do auto programing some chanels get program some don't


Hello
Check first your set top box's, or TVs antenna or ariel connection is tight or not. It it is Ok, if you are receiving signals from cable, ask the cable operator to check the signal strength at the cable end of your home. It is measure with a 'db' meter. If the strength of the received signal is very weak, the same channels should not mamorized, and strong signal channels only will lock in. If you are using external antena, try to reorient its postion.
Anyway your TV doesn't get sufficient signal strength.

Most of the channels breaking up despite auto retuning


could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

After retuning no signal for any of BBC


If your aerial is slightly out of line with the transmitter it will skip some the first time around. I had the same problem and just retuned and they returned as normal.

HAVE GOT A SWISSTEC 15 INCH TV BUILT IN FREEVIEW, BUT CA NOT GET ITV 1 OR CHANNEL 4 ON IT. HAVE TRIED RETUNNING BUT NO GOOD


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.

redo The retuning process is as follows:

  1. Press the [i+] or MENU button on the remote control to display the DIGITAL INFO menu.
  2. Press the BLUE button to display the MAIN MENU.
  3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
  4. Press the RED button to start the auto tuning process for all available digital channels.
  5. Wait for the process to complete.

If you wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information
