FYI, I accidentally cleared the NVRAM on mine once, and I imagine that that is about the worse you can do in the service menu. Everything's gone, al of your presets are gone, you are presented with a picture about the size of a very badly shaped A4-page and the tuner's AGC is messed up to so you get a ****ty image when you try to tune in on any stations.
To make things even worse, there are no more digital options in your 'PICTURE' menu, the set thinks it's a 4:3 television and it only recognizes 2 scarts... Quite a mess, I tell ya ;-)
I just drove over to a friend of mine who has the same telly but smaller (32PW9525), got into the service menu, wrote everything down, freaked my friend out by telling him I messed up his TV too - which I hadn't, but it was quite funny - copied all the values in my service menu, and apart from the geometry and the digital options in the 'PICTURE' menu, everything worked again...
Spent about an hour on geometry, got it even better then before the incident, and finally went into the 'DEMO' menu to toggle DNM on.
Switched the set off, back on et voilà... digital options in picture menu were back, and the geometry and picture were better than ever before ;-)
So what I'm saying is that if your set is really broken, I don't think it has to do with anything you've done in the service menu...
bye
