Hello, I have Samsung Ue46d6500 after switching on the screen is highlighted but nothing displays after disconnecting the connecting strip t-con with the motherboard and reconnecting the screen turns on and displays but only a few seconds after which it again dims. I exchanged t-con and motherboard and it did not help. Does anyone know what could be the reason?
ONE SENTENER SAID THAT IN D-CON DAYS I CHANGE IT the second is that if not t-con is definitely the motherboard but I see that with them such electronics as the goat d..trąbka I bought both parts from the walking TV with a compact matrix so the parts are definitely good
I did not check anything else
Added after 11 [minutes]:
I connected my computer through the pc connector and how to disconnect the tape from the t-con and connect it I see the image from the laptop but when I connect with the hdmi I can not see the TV anymore
SH120PMB4SV0.3 is name of the "bare" printed circuit board used for this T-con. Then, depending on the set up, he accepts different names ... Should be a sticker described as LSJ460HW01-S / LTJ460HW03-L - LVDS controller AMLCD LPF10A1 -DC-DC RT9979, i7814HS 2x. , i7975 i7959 Link for the matrix eg LTJ460HW01-J
What do you have when you turn off the left one ... then the right side from the T-con? There should be still a 400 Hz CMR module. , because it's 3D, Smart TV, Wi-Fi
This is probably your Main (BN94-04751H, PCB: BN41-01587E) It's from a good T-con VIN_12V 12.3V VCC33 3.24V VCC12 1.2V VCC18 (t_con) = * VDD (on side decrypters) = 1.75V AVDD (t_con) 17.15V VDDMHL = VDDMHL1 = VDDMHL2 = 8.6V VONE 31.8V VOFFE (-12.2) V VR 9.9V VSS (-7.4) V
There were various MBs, depending on the letters at the end

Hello Since I have a similar problem with this tv model, I decided not to set up a new topic and ask for help here. The problem with my TV is the following, after sealing the pin on the flex tape marked in the picture from the t-con plate, the TV started to display the image, unfortunately half of the image is covered with stripes as on the next photo attached, unfortunately I have not found a service manual for this tv and the scheme of this -con, please help or some tips on how to solve this problem, or maybe the problem lies on the matrix side? I wanted to add that now the t-con voltages look correct and at the moment when I remove the tape I secured this pin I have only 12V voltage that powers t-con. The voltage on the marked pin, after insulating it with tape, is about 7.58V, when the insulation is not 0V.
5krzych coped with this problem? Was it T-ton's or matrix's fault? In my UE46D6000, it highlights the matrix but does not display the image. If I leave only the right tape connected / looking from the back of the TV / it shows me the picture on the left half of the TV with stripes as in the above post. As it is connected only on the left tape the left side of the TV is bright and the right side is dark but the picture is not there. Maybe someone has any suggestions for damage? I would like to add that when I plug in both tapes I have the right voltage only on VIN_12V. I do not have any tensions at the other points. Both tapes work. I suspect that the matrix is damaged, but someone can make me that way
Thank you for your response. I have identical symptoms to you, so probably it is a specific fault occurring in these models.
Or maybe in that case someone knows where to buy such a matrix and what price can it be? For me there is the matrix LTJ460HW03-J. Or maybe there is a replacement?
For me, the matter is resolved. A fake matrix in the upper right corner.
The discussion revolves around a Samsung UE46D6500 television that exhibits a highlighted screen upon power-up but fails to display an image. The user has attempted to troubleshoot by disconnecting and reconnecting the T-con board, which temporarily restores the display for a few seconds. Despite replacing both the T-con and motherboard, the issue persists. Various responses suggest that the problem may lie with the power supply, the T-con board (model SH120PMB4SV0.3), or the matrix itself. Users report similar symptoms, including horizontal stripes and partial image display, indicating potential matrix damage. Voltage measurements from the T-con are discussed, with some users suspecting that the matrix is the root cause of the failure. Recommendations for further diagnostics and potential replacement parts are also mentioned. Summary generated by the language model.
