[dcaron614]

Hello, I have a Samsung LN40B530P7N tv that has a terrible picture display I have been reading and only found 2 listing on this forum about this tv and the issue that it maybe having I have tried more than a few things without replacing anything yet, but can't seem to get it working. and I could not get into the service menu screen that was listed/shown that is suggested in the post by hitting "mute 1,8,2 and power" and Look for options marked LVDS format which i could not find... here below is what the screen picture looks like...plus i disconnected one side at a time on the t-con board and those pictures as well as the menu screen that i could get to by pressing "mute 1,8,2 power

I hope some1 can help me pin point the cause so i can get the correct part needed.

picture 2,3 is with one side of the t-con cable out left then right

I'm gonna guess bad gamma ic. But I will wait for bud or Tom to chime in.

I would agree, gamma chip would be among the things I would test, however, I'm not aware of it affecting these models, only A-series, 2008 models. Not impossible, though - a pic of the T-con is necessary to highlight the gamma testpoints.

Thank you for the quick reply. here is a picture of the T-con board

I hope I can replace the board if that's it as I'm not very good in soldering ..lol
