In an act of gross stupidity, I entered the service menu of my 36ZP48 TV in order to adjust the slightest of vertical bowing on my 4:3 picture. This is so slight that I ignored it for two months, but I had a rush of blood to the head tonight and decided I would make it 100% perfect. In my ignorance, I thought that the only setting I need write down was the RCUT 0410H 40H 01000000B and I merrily, like a bull in a china shop, changed a lot of the other settings. In my panic trying to get back to the original picture settings I have totally destroyed the picture, both geometry and colour. Will somebody please reply to me and let me know the 23 other factory settings. Thanks a million for all the trouble you will have to go to. I am desperate.
