Re: Horizontal black lines on screen - please for your help
Finally I found the problem. I checked the main board and many of transistors are fail.
I noticed something like evaporated liquid at the bottom of the doard. At first i cleaned up with isopropyl alcohol but nothing changed. After that I started to measure transistors and found that many of them gave power front and reverse.
Unfortunayely I cannot find one board in reasonable price. If you have an idea where I can find one (BN94-03388B) in good price you are welcome.
Anyway, thank you all for...

Hi Lotas,
I tried to mask these contacts you suggested me but with no results. Once I covered these contacts TV returned me black screen.
I tried to cover some other pins 6 by 6 without success.
Maybe I am wrong but I think that that the problem is caused by something else since once I unplug one by one the ribbon cable I dont take half clear picture. I take half picture with lines in one case and half picture black (& white) in the other.Leave a comment:

Update:
I have tried to disconnect once again the ribbon cables, one at a time to see what happens on the screen.
When i disconnected the right ribbon cable I saw on the right half of the screen the content with horizontal lines. The left half was white.

When I disconnected the left ribbon cable I saw the right half of the screen just white and the left half black.

Horizontal black lines on screen - please for your help
Hello Everyone
I need your help to repair my poor Samsung TV which decided not to let me watch my favorites series in the afternoon. Suddenly black horizontal lines appeared on the screen making my life a hell

I have seen many youtube videos with guys who put a tape in ribbon cable and TV fixed in a magic way (I have tried without success).
My TV model is: LE46C750R2W
