50V10. Came with 1.19 fw. Had the THX yellow/green issue. The first panny 1.28 SD fw update didn't work to fix the problem. Had a new 1.28 A-board installed, problem fixed, PQ great. Don't really know if I have a rising blacks issue; although my side bars are lighter than the bezel (can't remember if that always was the case), black images within scenes appear to be as black as the bezel.
Panasonic rep's (he's a trainer too, and has been with panny for 17 years)visit to see if I need a further THX update:
The panny rep just left after checking to see if I needed a fw update by looking at the main SM. I do not, all is good re the THX issue. He said that those with the THX issue will not need a new A-board, but rather a SD fw update done by an authorized panny rep (unless you are in the hinterlands, in which case they will probably mail the SD card). So, after some trial and error, it appears that panny has gotten the THX issue controlled with a working 1.28 fw update.
For those who still have a visible THX issue, the rep will personally install the 1.28 fw update. They just don't want to take any chances that something will go wrong with consumer installs.
The rep said that the fw update shouldn't change settings and here are my main menu SM settings (which are the same as Jackal's-he had the same A-board replacement as I did):
Peaks Soft 1.280
Peaks EEP 01.02.0697
Peaks Boot 1.00
LSI Data 0.00.0f
Stby Soft 1.00.00
Stby EEP 1.15.21
Stby ROMCOR 1.04.00
PDP Soft 02.51
PDP EEP 51.61
PDP FPGA 51.06
PDP PDROM 51.24
The rep wouldn't go into the CUTS area. I was hoping to see what my CUTS were, before and after (if he made an update).
I asked him about warranty status if one goes into the SM. His bottom line was that "Panasonic reserves the right to void the warranty if the SM is messed with." I think this is in line with something that I have read on AVS that going into the SM may void warranty if the changes made had a detrimental effect on the TV. So, if you make changes in your SM, visa a visa warranty, it just may be up to the tech who comes to your house.
Rising blacks issue:
As to the rising blacks issue, he said that he just got a memo today from panny about it. The memo said what we have already quoted from the Panny PR
folks that was recently posted. Control of black levels may have been too aggressive with our sets and will be made more gradual with the newer 2010 sets. He didn't make any comments that weren't within panny party-line. In other words, no help to us-nothing about a fix for us who have this problem
