martyh: Regarding the possibility of software updates rectifying this problem, unfortunately the answer is in my opinion no! as rectifying these type of issues generally has to be carried out via RS232 socket transfers or directly into the appropriate test pin area on the PCB if factory updated, that is "if" the manufacturers provided the software for such an action in the first place, something which I very much doubt as the problem would not have been known about then.

That of course being the norm with any digital receiving device hence the reason for the constant stream of software updates one hears about, and the greater the number of updates seen for the same model an indication that the previous one was, to put it, "a shot in the dark" in an attempt to cure whatever defect it was intended to correct.

Your problem does though have slight similarities to a much later manufactured range of Sony TV's that suffered switch over instigated problems, Sony's answer to the problem was to provide users affected with a software update on a £15.00 refundable deposit flash drive to be inserted into the offending TV's USB socket, but to my knowledge Sony is about the only company that has used this procedure.

I have to admit, that I personally feel that the only way your problem is likely to be overcome is by replacement of tuner, the problem there being the cost of such an action would likely exceed the cost of just purchasing a Freeview box and coupling this into the TV's scart socket, or if you didn't want a Freeview box to be seen then use one of these small wedge types that fits directly into the TV's scart socket.

As I am rather curious about this problem from my own point of view, and at the first opportunity I fully intend to check if the TV tuners part number is different between the 05 suffix models and the models without, as that would give a clue if Philips had fitted updated tuners in some later models, so maybe you could let me have the TV's serial number as hardware update notifications on service sheets use that info to indicate when a switch was made.

Regarding the use of the old Virgin box, if you are referring to the original Virgin "Free TV" branded box then its worth giving it a try connected as you have mentioned plus a scart lead coupling between the V box and TV, but its really a hit and miss thing as the tuner spec I have on these only gives the very basic of information and so you might find that it doesnt work for the same reason as your Philips.

By the way, this is a link for one type of scart Freeview receivers I referred to, but there are a few other brands available as well.

Janice: There has to be something else involved, as there is no such thing as digital or analogue distribution amplifiers, as they amplify anything.

Hi JB38
Tried the bit of wire and screen freezes with
no signal message.
Interestingly enough the frozen picture still
has the interfence and hum on it.
Been watching it and noticed that even with sound muted the hum is still there on the picture.The hum is loudest on a full white screen and practically dissapears on a red screen. The picture interference looks like
the heat haze you get on hot days and seems worse when there are a lot of vertical colour
changes and dissapears on something like a long range landscape picture.Shame they don't
still transmit the test card.
The TV is a 14" Bush CRT says AK46 on the back (I still think that a CRT tube gives a
far superior picture compared to LCD)
Just popped into ASDA on the way home and they'd sold out off most of their Freeview TVs guess no-one told them about the switchover:)

Got a strange problem here.

Since the 18th my PVR is not picking up anything on UHF28 (Arq B, Mux D, whatever you want to call it!). My fairly new Samsung TV picks it up no problem though, and they're connected in-line.

The box is an old Asda one, the Durabrand DPVR801. I'm 7km from Crystal Palace (bearing 126°) and am using a set top aerial.

I used to need a powered amplifier to get a good signal on all channels. I tried removing it from the setup to see if it made a difference, but no luck.

All other channels seem to be fine, but when I do a manual scan on 28 it just shows nothing at all.

Like I said before, the aerial lead goes through the PVR into the TV and the TV picks the channels up fine.

Anyone got any ideas? I can watch the channels on the TV, but there are occasions where I like to record things on ITV4, so would prefer to get this fixed if possible!

Many thanks.

ok jb38 - yes I'm asking lots of questions, as you are, out of curiosity. I expect you are right re 'just get a freeview box.' Interested to learn about the whys and why nots on my Philips model. On the updates, I DO have a serial port (9 pin like mouse type on a compo) and a common interface slot - both at the rear, along with the modem previously mentioned. Not much about how to/why to/when to use any of these, or what they are for in the manual! Re model info rear stickers read :-

22AV9625/32

Will mull your last post a bit more, and come back to you.

TV updates are mainly to do with apps like bbc i player they have nothing whatsoever to do with the changeover or loss of signal

David How: I was just having a read at your posting and wondered exactly what you are using for an aerial? as anything used in Dulwich that has more efficiency than a simple set top aerial is liable to cause a multitude of problems through signal overloading, and with any indications seen as far as the strength or quality is concerned being totally inaccurate as the tuner will be verging on instability thereby giving incorrect indications.

Big Mart: Where signals from more than one transmitter are picked up by the aerial, different pieces of equipment can decide to go with different transmitters.

Go to BBC One HD and then bring up the signal strength screen. For Crystal Palace the UHF channel used for HD services is C30.

According to Digital UK Tradeview predictor you may be able to pick up Sandy Heath (C21), Hannington (C39) or perhaps Hemel Hempstead (C47).

David Taylor: Going by your latest report regarding the symptoms seen on the TV makes it rather obvious that something in your system is causing severe instability to occur, are you positive that the scart lead between the box and the TV is OK? what to do is wiggle each of the two scart sockets in turn whilst observing the interference, as if the main earth has come off inside the scart plug (or TV's socket) that can cause problems.

The other point is that this model of TV is made by Vestel (Turkey) and is notorious for bad joints in various places, so do you have any other devices in the house that you can connect into the TV's scart socket to verify that its OK?

martyh: Thanks for that info, and which I have copied down and will have a check on early next Monday or Tuesday depending on what my non-domestic electronics work schedule might dictate.

The other point about your problem being, that even if Philips (or any other company) customer services puts you through to the technical service side of the help line even they don't get involved with the nitty-gritty of in-depth fault finding and are inclined to believe what they see printed in an info sheet given to them is the gospel, which in many cases it isn't.

Anyway I will get back on this.
