Hello, I have this TV for repair and the symptom is that every black background has a red colour like noise. It is not visible in the menu though. I have removed and cleaned all the flex / cable connected on the boards, nothing changed. Is that main board issue?

Re: Samsung UE65F9000SLXXH
in this case you need first to test panel reaction after you connect the one connect and feed video or other ports signal then disconnect one ribbon at time between T-CON and panel. to check if there are any different with it.Comment

Using the antenna signal (aerial) the screen turns black when I disconnect either of the T-Con flexes to panel.Comment

Re: Samsung UE65F9000SLXXH
its difficult to trace the signal walking thru. need to take a look on the other boards with black cover.
BTW: did the "one connect" socket connected to video processing boards ( the middle one ) via the Yellow socket clip?Comment

Re: Samsung UE65F9000SLXXH
The One Connect socket is connected in the main board. The yellow socket connects the main board with the 3-D board if that's what you are asking.Comment

Did everything you said, nothing changed. Could it be a defective panel?Comment

Re: Samsung UE65F9000SLXXH
if you did freeze or heating ICs 110-111-112 with no change.. then you have 90% BGA at the big chip.. look on the left side of the Ics where the print line goes.. at this side of the chip need flux and refellowLast edited by Diah; 03-05-2021, 06:13 AM.Comment
