Made a nice score on this thing today, mint condition and ended up just being a software issue. If you run into any of these LN-T4x6x series TV's and you are seeing any of the following issues: Blue (or other color) tint, psychedelic colors, negative colors, 2-3 horizontal lines, it is probably a simple fix. I can see it easily being mistaken as a hardware issue, and funny enough a new motherboard would probably fix it. I don't want you guys to go wasting your money for such an easy fix.
Samsung released a firmware update that set values incorrectly in the service menu and when customers call them about it, Samsung tells the customer they shouldnt have installed the firmware and their TV is broken. (reported by multiple people online and the gent I picked this up from.)
Here is the fix:
1. Make sure the TV is off. Then on the remote, slowly press MUTE, 1, 8, 2, POWER. Wait for the TV to come on and the service menu should come up.
For psychedlic/negative colors: Goto "Option Byte" then "Lvds Tx Fmt".. Change from JEIDA to VESA. That should fix the issue.
For blue (or any other color tint): This one is more involved. Probably easiest to do with a PC that has VGA and HDMI connections. You need to find an 8x8 checkerboard image, or use the one I've attached. With the PC displaying on the TV and the checkerboard JPG full screen, bring up the service menu and go into Calibration. Run the calibration on both HDMI and VGA, once for each or until it reports "success".. I had to try a few different times for some reason and finally got it by using the checkerboard for my windows background and hiding the taskbar/destktop icons.
Also: Make sure the SCREEN SIZE is correct:
Panel Option = 46AMW for LN-T4665 displays, and 46AM for LN-T4661 displays.
Make sure that if you own an LN-T4x65 that your Lvds Tx Bit = 10bit.
Make sure if you own an LN-T4x61 that your Lvds Tx Bit = 8bit.
If you own an LN-T4x65, your should change your model so it says "Tulip Side."
If you own an LN-T4x61, you should change the model so it says "Tulip."
I scored this TV for 60 bucks and fixed it in 20 minutes.
