Peter: If manufacturers started using F-connectors, apart from the fact that adapters would often be needed, people would go connecting satellite dishes to terrestrial receivers.

martyh: Well there shouldn't really be any noticeable difference in the overall colour of the screen area when the set isn't switched on, although on some tubes including flat screen CRT types, the corners can appear to be slightly darker by a combination of the glass being thicker in this area as well as it turning inwards. i.e: not quite so much looking straight through the glass but slightly diagonally.
That said this would not affect the picture size any, and even although you might have set the TV's picture ratio to auto you have make sure that widescreen (or 16:9) has also been selected on the Logic as well, the selection being offered on "First time installation" under "TV type" using the <-> arrows.
Maybe you could have a check on that.

Hijb38. As per my previous posts I have tried every combination re: unifying settings between my TV and the Logic, including altering the extensive options on the TV, whilst trying differnet modes on the Logic.Just to refresh the leaflet for my TV is here: http://download.p4c.phili….pdf and maybe you may be able to look through it and spot something that perhaps I'm missing in the technical blurb? Thanks for your reply to my last post but there has definately been a 'physically visible' change in terms of what I see (when looking close up) when the TV is off (and unplugged), bearing in mind I can clearly see that the 'black' edge surrounds on the actual screen have definately become bigger, and un-uniformed (that's to say there is no longer an even measure (of non picture showing area around the four sides of the screen as was before)thus seemingly reducing the viewable area. It's hard to get this across in writing on here. However, the problem still persists whereby I have to ask why would this picture size thing suddenly change without me altering any of the settings on either the Logic or TV all of a sudden, just like that? ie: switching the TV off one week where it was working fine, then switching on the next to find it not. I am a persistant chap however, and will keep trying over this weekend to see if I can do something that will fix the issue, and of course let you know how I get on, though from what you siad last post, maybe it could indeed be a problem with the Logic. THANKS for all the help and suggestions on this jb38, am determined to get to the bottom of it! Regards, martyh

martyh: Yes, but its not so much a combination of both devices that I would suggest that you concentrate on but making sure that the Logic is left permanently on 16:9 and then only making your ratio selections on the Philips, these being either 16:9 movie expand with or without subtitles, or alternatively just being left on automatic, as there isnt really any other adjustments that you can choose, unless that is you had previously selected "zoom" whilst on one of these modes but which had reverted to normal.
By the way I have the manuals for both these devices.

martyh: Also meant to add, that if nothing you do seems to resolve that issue then carry out "factory settings" on the Philips, as that guarantees that you are starting afresh and then you can take things from there.

ok, thanks jb 38. I tried several attempts flicking through the aspect ratio on the Logic and on the 6th attempt in a row, the screen corrected itself. The picture being slightly better, also helped by use of the DNR button on the TV remote. Picture is now even. I think you are right re picture quality etc, in that I can no longer benefit from the processing features as seen before when pictures delivered straight thru the ariel, as some options no longer work using the Logic with scart connection. So I think I just have to put up with how things are, or when enough money saved up, buy one of the latest HD TV's. I think I'm done on this now, so thanks for the time and effort you've put in. It's just a shame that the format for the new signal made my TV somewhat redundant, when I'm sure it still has years of life left. Philips could also have been more pro-active as well I feel, leaving customers thinking their TV's would be ok for the new signal, when they were not but I know the government has quite a bit of blame there. I still feel cheated thinking about the £1600 I initially forked out though!! Regards, martyh

martyh: I would suggest that before you completely resign yourself into having to purchase a new HD TV you should try and borrow a normal Freeview box from someone for purposes of comparing its picture quality (after having been adjusted) with what you are getting from the Logic scart receiver.
I fully sympathise with your feelings regarding your TV being effectively redundant as I know a number of people who feels exactly the same, and especially if the CRT's in their TV's are still OK and not suffering from low emission because of the tubes cathode being on the way out, as should a TV with a good CRT be sat beside a modern LED illuminated flat screen LCD set, the picture on the LCD / LED set always looks positively flat and lifeless, and I havent seen one yet that doesn't.
Plasma TV's aren't quite so bad though, as just like in a CRT set the actual screen itself is illuminated and not being done via a back light as in LCD sets.

Thanks jb38. Out of interest, would a new flat panel TV (of same screen size 32") consume less electricity than my Philips, which consumes 175 watts (normal operation), not forgetting the logic which consumes another 4 watts - total 179 watts please? martyh.

martyh: Its very difficult to give an exact figure, but the average I get using a few 32" models as examples, e.g: Sony / Panasonic / LG's etc gives a figure of around 120 watts, one of the Sony's only being listed as having 90 watts consumption.
Plus of course you wouldn't really be using the Logic with a new set anyway, so its really out of the equation.
Will say though, your Philips CRT set does seem to be a bit greedy on power consumption, as a 32" (4:3) Panasonic CRT set with pro-logic sound that I used to have only consumed 140 watts, as I used to run it from a 175 watt 12volt / 250 volt inverter when the power failed, the inverters cooling fins only ever becoming mildly warm albeit there wasn't that large of a power loading safety margin.

Thanks jb38, I see. LED TV's are on the market now, any opinions on them. Not that I can afford to change mine yet, will hang on to it for the foreseeable future, unless I have to replace for some reason.
