42PFP5332D/12 NVM reset mistake

Hello,

first of all, my apoligies for writing in english, but i can barely understand german :-). Some presentations: i've been a tecnology fan since i was a child. My love with tecnology began when with a Commodore 64, writing little programs in basic (mostly coping and modifying them, like the baloon one which Commodore made available) and playing lovely games like Mission Impossibile, Forbidden Forest, Aztec Challenge, Spike's Peak and many more. I also bought a ZX Spectrum, then moved to the almighty Amiga 500. On the 500 i started learning programming in C/C++ with Lattice C compiler. I remember copying Lattice to the ramdrive to speed up compilation :-) (i had a 2MB [or was it 4?] expansion installed in the side port). After A500 i bought the Amiga 4000 and had loads of fun (but also some sadness for the slowness of AGA chips). My friends and i used to meet to play Amiga games togheter, or just for talking about Amiga utilities, playing with workbench and so on :-). In the sad days of Commodore demise, i sold the A4000 and bought a Pentium 75. I remember being angry at it, in the first days, because of stupid real mode's (or V86 mode) segmented memory addressing until i found out about Protected mode and DOS4/GW (seen used by Carmack in Doom), which helped me in having fun again with programming. Watcom C was my new programming tool

Nowdays i work as programmer in a small software company (Visual Studio <3), doing some 3D and general programming (database and so on). I have an iPad 4 on which i found many lovely indie games (began hating big block buster-all-the-same games). Im also "finishing" a game on iPad, or at least hoping to :P. It's taking ages (busy life, a classic) :-)

Story is, my TV, a now old 42' plasma TV, model 42PFP5332D/12 always had problems holding scanned channels, since the very first days. Years ago, when we bought it, i told my father to return the TV because it was obviously defective, but he didn't listen to me (stubborn!). He started playing with it until he was able to memorize channels and have the TV keep them after being turned off and on again (however it didn't hold them completely, but he didn't care).

Yesterday, because there was a missing channel, even if i told him not to, he scanned channels again, and the memorization problems went back, but this time he couldn't force the TV to hold the channels again... So i started digging on the internet and found the service manual, along with your posts and posts from other ppl. So i entered SAM mode and played with the options and i also resetted NVM by entering 170 at address 1. After NVM resetted the TV was in a sad state, wrong colors, missing options, and so on. I've been able to fix some of my problems by entering the correct op codes (again in SAM mode, in which i can enter by inputing 062596 on the RC WHILE BEING IN ANALOG MODE, i cannot enter in SAM while in digital mode! [not mentioned in the manual grrr!]) but atm the image on the Tv is not centered so i have a big black band on the right and on the left the image is cut (misaligned position and size :/).

Sadly, there is no image alignment setting in either SAM mode or in the other modes i tried to enter .

One thing i wasn't able to do is to set the panel code. When i enter 062598 and press MENU then write the three digit code my Tv doesn't do anything (i've read that it should go in stand-by, but it doesn't happen). I've read in another model (similar to mine, or at least i hope so) that i can input the panel code by writing it at NVM 400 (dec) address (my panel code is 083, as written in the service manual). I've done that too, but it doesn't fix the image aligment and size problem.

Do any of you have resolved a similar problem?

Thanks in advance
