I spent the last few days playing around with some of the RS232 commands listed in the service manual. Anyone with a straight through serial cable and hyperterminal can use them. Disclosure: Please don't play around with these commands unless you know exactly what you're doing, especially those which are entered in the SM.
Some I found interesting include the different picture modes shown below which actually CAN be selected in and outside of the SM, but of course none of the changes stick once the panel is turned off. For instance open a hyperterminal session and type: pavs06 and the tv switches to Pure mode. Alternatively pavs08 changes to a bright ISFday. Interestingly if you hit display on the remote it still shows "Movie" but you can actually go into the settings and alter this quasi ISF-day PQ setting. Of course turning the TV off and back on reverts to settings stored in NVram.
BTW none of this information is new, as D-nice played with these settings last year. Nevertheless I found a few interesting tidbits about what could potentially make the NE different then the Elite, and here's what I found.
1. The panels are virtually identical, as just about all of the assembly's (main, x, y, sensor) share the exact same part numbers.
2. Typically electronic devices are set for a model and region when it leaves the plant, usually somewhere in the service menu that determines which features to activate, such as PAL mode. Issuing the QSE command shoots off this information in cryptic code but there's nowhere in the SM that tells you how to set the model and region, for obvious reasons. There are some values in the SM that the manual describes as "reserved" with a cryptic outputs of "****". Not sure if these values are being hidden purposely, or I'm barking up the wrong tree.
3. There's an adjustable identification resistor on the the X drv assy that identifies the model to the sensor assy but it's unclear if the distinction is 50 vs 60 inch or NE vs elite. The part number of the x assy is: AWV2546 which pioneer parts says works for both the 5020FD and Pro-111. Again I could be barking up the wrong tree. The ID resistor has to match the software build of the unit or else it will throw an error code. Even though the FW updates are technically the same file, that doesn't mean both units extract the same pieces from it during the update. The SM info page lists the software version. It'd be interesting to know if the builds are the same.
4. Serial numbers can be manually entered in the SM. Perhaps changing the SN an elite range
might do something? hmmm
Besides that the manual states there's 4
white balance tables within the display adjustable by switching whats called the raster mask. a 60hz, 50hz and 72hz and 75hz. Go figure.
Boy I wish I had a cracked 5020FD to play with.
