Introduction

Board Specifications:

Samsung UN60FH6003 Timing Control (T-Con) Board P/N BN96-28944A (BN97-07663B)

Symptoms:

- TV turns on

- Have sound

- dark screen (backlight on, changes brightness depending on content)

- can turn TV on/off, change channel, etc. with remote

Other symptoms this fix would most likely solve:

- picture shows inverted colors

- screen has vertical lines

- half of the screen has no picture (backlight still on)

- symptoms that suggest the video processing unit is malfunctioning, while all other things seem to be working

Diagnosis:

- T-Con board failure (most likely), everything except picture was working

- Main board failure (less likely), main board couldn't process visual information

Fix:

1. bought replacement T-con board (I bought from ebay) - Board P/N BN96-28944A (BN97-07663B)

2. open TV by removing back cover (place TV face down, remove all screws, lift plastic back off)

3. remove metal plate that covers the T-con board, at the bottom of the TV. use caution not to damage ribbon cables attached to the T-con board

4. disconnect top ribbon cable by squeezing the sides of the adapter and pull it out carefully

5. disconnect bottom two ribbon cables. flip up plastic cover on the adapter/socket that locks the pins. lift out ribbon cables.

6. remove and replace new T-con board

7. reconnect all ribbon cables

8. install the metal plate, tv back cover

I have a 50" Samsung Model UN50H6201 with the exact problem you described. Seems like the fix would be identical, except that I would get the T-Con board for my model. Correct?

Yes, the T-con board fixed the symptoms I have. The TV is still working perfectly today. I just opened up the TV, copied the board part number, and bought a used part off ebay. Good luck!

Thanks for the info, I have similar issues. My set corrects after being turned on approx. 20 minutes or so. Did you have similar symptoms? TIA

No I did not have similar symptoms. My TV was good for 13months, and no picture the day after. I do want to make wild guesses... but something that works after warming up might have to do with a bad connection or a dying piece of hardware on the board...

(Also, I did not have issues with the ribbon cable connection. The ribbon cable is the very flimsy thin strip of the signal lines that connects the T-con board to the LCD panel. There are two of them. I used the old pair.)

I have UN40EH5300FXZA I was try to use my Note 4 w/ MHL adapter on my tv when signal cut & couldnt regain As i opened phone end of cord i saw it had broke its connections, soldered back together and just as I finished my friend walk up picked it up, of course I had just finished and was trying to test the connection with my phone prior and I left it plugged into the HDMI cord. When he turned around holding it it arc'd out the wires causing lots of Sparks, TV flashed & then cut to Grey screen with horizontal and vertical lines scrolling across the screen. Now whenever I turn the TV on it has pristine picture in all the different video input modes however after 1 to 5 minutes my screen Cuts back into the grey mode with horizontal and vertical lines scrolling across the screen I am unable to control the TV via control panel or remote during this it then cuts to a black screen then through startup and repeats till I pull the power cord question is can you tell me what I need to replace?
