Samsung LNT5271FX/XAA : Weird Solarized Screen Colors

[Jayrcee]

I have a 52" Samsung LCD, Model LNT5271FX/XAA that just last night started exhibiting a weird screen. The picture and audio still works but it looks like a negative image with bright colors. It happens on all inputs, even the on screen menu. I just finished fixing the capacitor problem with this set less than a year ago and now this. Any help diagnosing the problem would be greatly appreciated.

Anyone have an idea of what could be the cause?

I would try factory reset: see the code for SAMSUNG:

Reset didn't work. Is there are way to diagnosis a bad main?

Can you post close up photos of the Tcon and main boards?

Yes, I can get some photos of those parts. Any particular area of the parts you want me to focus on?

The main board has the video inputs on it. The t-con is at the top of the LCD panel and connects to the main board.

Here are the pics as requested. If someone can tell me how to get that shield off of the t-con I can get better pics of the board. I removed the tape but couldn't get it off.

Remove the cables out of the way and give it a little pull, its usually stuck on with the thermal pads on the main chip.

How do those 4 connectors at the top come loose? Do you pull on the white tabs?

if you look at the socket that the ribbon cables go into you will see that there is a little hinge... just hook under the dark bit of plastic on the side the cable goes in and gently lift up, this will unlock the cable and you can pull them out. To refit just put the cable back in and push the clip back in place

I think your t-con is bad.need another.

Is there any way to check to make sure? I would hate to throw parts at it. I was also told it may be the main board.

I would point my finger at the T-con

Find a reputable seller via ebay who will accept returns in the event it is not the one... at the same time the T-con is the cheaper of the 2 and beats spending $80 on a main to then find its the $30 T-con

I know I stated it maybe the main in a previous post but didn't read your post correctly at first.

Have you tried changing PANEL OPTION or LVDS MODE in service menu?

I did a factory reset a couple days ago. Would that have changed those options? If not, what would I change them to? Thanks!
