Hi avs members , i need some help please , i went into the service menu today on my samsung ln40a750 and adjusted a file name (dim..something something) and now my tv screen is in total black ..there is sound and i can turn it off and on and change channels but nothing on screen
.. i try the unpluging for 5 hrs and tried the remote factory reset (hold exit for ten seconds and push left select yes) and the tv did turn off..so wanted to see if anybody can take some pics of their service menu screen so i can try to adjust it without seeing the screen..thanks in advance

Well, you're also going to need to know what you set that option to. And the order of the settings for that option.


I have the A650 and I'm fairly sure the service menus are similar, but the Option Bytes will be different.
