First, thanks to all who add info here. And, if this is not the best place for my post, sorry! I couldn't post anywhere else, it wouldn't let me..

I tried some tweaks from the xxF59 Tweaks thread, but didn't see an improvement so I wanted to undo the changes and just go back to the original settings to start over. I had read here, or maybe elsewhere, that the FACT RESET would take the set back to original factory shipped settings. I also saw advice of using this option as an attempt to fix this or that... To shorten the story, I USED THE FACT RESET option. After starting the set back up again it seemed fine, just needed to be set up again. However, I can't seem to get as good a picture as previously. Also, I notice some things here and there such as the "aspect" button on the remote no longer working, and the on screen menu seems different in some way (can't put my finger on it). Anyway, can any of you pros provide any useful info on what I've done! I hope it's not bad, but give me the facts if you know anything about this. I sincerely appreciate any reply.

I think you read it totally opposite, everything I've read says to write down all your settings before changing anything and to NEVER use the factory settings.

Sorry, you might ask someone with this model for their settings and you might be able to get it back the way it was.
