jb38. Had a chance to mess around with all the settings on my TV, plus the logic adapter. Have tried every combination I could think of without success. Point to note, when I first rigged up the logic, there were no issues that I remember regarding the picture not filling the whole of the screen area. I only watch TV occasionally at the weekend, and in the first 2 weekends, it was fine. It's only the last couple of weeks that the picture has played up, so am stumped as to why things have changed. Could it be that a week signal may result in some information not reaching me, or that maybe some information is missing from the signal? Seems strange it was ok at first, and now it's not. Point to note, I also tried swapping the logic using the 3 different scart sockets (EXT1, EXT2, EXT 3) on my TV, and noticed that the frames of each differ ever so slightly in terms of positioning. ie: one would move slightly more to the right, or to the top etc - however still all leave too much gap at the top and to the right (as per original post/problem). The natural position re: picture for my TV, is when set to auto, and this has never presented any problems - including when I first used the logic, So I am wondering if for some reason the logic cannot process all the signal information, as maybe it's missing or not all of it is reaching me? Only have one TV, so cannot test with another - also neighnours mostly have skysat or cable, so cannot varify/test with them.

jb38 UPDATE!!! Dead phosphors/'pixels'? Have physically looked at the TV screen and inspected it! I am now wondering if some of the display phosphors are dead. On observance of the screen (when TV off) I see the main picture area coloured a grey/green, with the outer edges in black. The grey/green area does appear to have shrunk (in effect) as they do not extend all sides, to where they were originally, thus leaving larger areas to all sides in black, than used to be. (if you see what I mean), so my suspicion now is that there is a fault with my tube (ie it's on the way out), rather than anything else. If you concur on this, I wonder if you'll agree that this is a most strange coincidence. ie. That within weeks of me using the logic, a fault has occurred with my TV screen? How bizarre is that!

Does anybody else wish that the TV industry would move away from using coaxial plugs and sockets, the poor quality of which often leads to reception issues, and towards better quality, more professional connectors?

Peter, I agree with you, I use F connectors for all my RF connections

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.
