Hi

I have just purchased a Panasonic PVR with +. It set up fine with HD etc but is missing the COM 4,5 & 6 with the weaker signals. Strangely, my Panasonic TV'x inbuilt tuner receives these channels.

Why is Freeview+ not able to receive weaker channels when standard Freeview can?

Is there anything I can do to get these missing channels on Freeview+?

Thanks

John: Different receivers work differently and some may be more sensitive to others. That is both sensitivity of signals and immunity to .

I would not read anything into "" and "Freeview+" as these are simply brand names associated with non-recording and recording devices.

Have you had your Group A replaced with a one (or a second Group C/D aerial fitted)? If you haven't had this done, then that will explain poor of the COMs. If you would like me to explain what this means, then let me know.

Many thanks for your reply.

I originally had my replaced so that I could receive , but I do not know what type it is.

Both my Panasonic TV & my cheapo Alba tuner receive these , but the Alba has a poor (ghosting & reds sometimes flashing blue).

The new Panasonic PVR has a very good picture , much better than the Alba, but the Alba gets the extra channels.

It seems that there are two anomalies here:

(i)I have two Panasonic tuners, one gets Com4-6 and one doesn't.

(ii) The Alba has worse picture quality but picks up COM4-6 whereas the new Panasonic tuner has great picture quality but doesn't get COM4-6.

I would like to use the new Panasonic PVR to replace the Alba, as it is better in several ways. Unfortunately, the I use most often is on COM6.

Any suggestions you have or things I could try would be greatly appreciated.

Best
John

John: I would agree that there are two issues.

(i) Issues with :

I think that the issue won't be with your as you have had it replaced as I expected you might need to have done.

Is this a new problem?

Where does your aerial system serve? Does it just go to one point, e.g. the lounge, or is it split and if it is split is this a powered /?

If there is more than one aerial point (i.e. it serves more than one room), try connecting it to another point and tuning in the Panasonic that doesn't up the COMs. If there is manual tuning, then use it. are COM4/SDN=, COM5/ArqA= and COM6/ArqB=.

I don't think that the issue will be to weak a (COMs) signal at your aerial. At 6 miles from the , you have clear line of sight (assuming no local obstruction).

I came across this of Balvenie Castle and the transmitter can clearly be seen on the horizon:

Panoramio - Photo of Balvenie Castle

The image can be clicked for a high resolution one and there is no doubt that it is the television transmitter.

There is a possibility to be mindful of that the signal level being too high with the clear line of sight to the transmitter. For this reason, amplifiers should be removed if possible, if only for /fault finding purposes.

A set-top aerial is another way of testing, it providing a lower signal level (assuming that it's sited in a suitable place).

(ii) The picture issue from the Alba is likely to be an issue with the connection between it and the TV or a problem with the connection on or input connection on the TV.

There are two commonly used formats that are connected using a scart lead:

1. Composite : This uses one conductor (wire) to carry the video. By its very nature this means that all the picture is sent down one wire (and obviously split up as necessary, as it were, at the other end).

2. RGB: This stands for "red, green, blue" and this uses a separate wire for each colour. This provides a better picture than composite video because it keeps the colour components separate.

The fact that you are saying that one or more colours is lost intermittently suggests that this is using RGB and that the problem is an intermittent connection with one or more of the three conductors. Perhaps try another scart lead or try connecting it to another television.

It's usually the case that TVs that have more than one scart socket on have one that accepts RGB signals and this is usually Ext1 (or AV1). So if you remove the scart plug from Ext1 on the TV and plug it in to Ext2, it may appear to solve the problem, but you will probably have just connected it using composite video.

The ghosting you see if likely to be an issue with the scart lead.

Many thanks for that .

I can now get all of the stations. I resolved the problem by replacing the HDMI . Presumably the first was faulty.

John: Good to hear you got it sorted.

It was the HDMI lead; as simple as that!
