Hi all, I have some really great news for Pioneer 503HDE plasma screen owners. I have recently been talking to a Pioneer technician that has shared a little inside (ground level) news with me. Right then, straight into it. The best news is that Pioneer are planning to offer upgrades to the 503HDE tuner box to make it PAL progressive compatible in the Autumn (which I am also told is when a standard should be agreed). No upgrade plans have been made for the MXE commercial model unfortuneatley. Other ammendments are to the selection of AV inputs. When using component YUV (no auto-switching) we currently have to cycle through the AV input settings, which activates each input as you pass it. This will now be more direct and faster. There is also talk or revamping the way teletext is cycled too. How this will work I am unsure of as an extra button would be required on the remote control. (any guesses are welcome), unless they intend to upgrade the remote as well, which seems unlikey but still possible. He has confirmed that the 503HDE has an 8 bit processor and the MXE is a 10 bit, the latter having a superior grey scale. This is also being talked about as a possible upgrade. How this will be done he couldn't even comment on as he said it was way too early to blueprint. Interestingly enough he also commented that the 503MXE model is not a true PAL progressive compatible model and has been misinterpreted as being PAL progressive compatible. Even though it will display an image the output is NOT guaranteed by Pioneer. He has now lab tested over twenty odd MXE models and found differing outputs on a number of them when connected to a PAL progressive outputting device (sorry I forgot to ask which model he has been testing them on, will try to speak to him again later). He notice on some models after a very decisive lab test that part of the screen was missing or the screen was very marginally overblown (again missing part of the film/picture). To conclude at this stage I have also been given the 503 HDE engineer code to access the technical menus which are very comprehensive. It gives all the basic information such as Firmware Version, OSD Version and model Version plus lots more. I lost count after 120 on the menu options with 13 pages. Some of the menu options are test programs such as pattern mask test, full mask test and mask vs frequency test as you would expect. Other options are PAL vs contrast, PAL colour gain, comp HDTV contrast, data copy (for download I presume), RGB drive (individually set), GAMMA level, three trouble record markers, plus lots more. On page one there is a Monitor accumilated time record, a tuner box (center) accumilated time record and a Pulse accumilated time record all with reset facilities. I hope this news cheers some of you owners up, out there. If you want to know the engineer code please PM me. If anyone has the 503 MXE model please let me know as I would be interested to see if the code works on this model to.
