Then you need to check the signal lines at the HDMI and DP inputs for resistance relative to ground, if you connected it “hot”, that is, the monitor was connected to the network and the source too, and when connecting the connecting cable, a discharge could occur and then the processor would die, or maybe there was lightning ...Comment

I was retesting the mosfet and capacitor this morning, and they looked okay. i turned over the board to check whats on the other side, and i found this mosfet (has code 1E on it) directly below. I tested and got the results gate (black probe) to source (red probe) i got .OL but in reverse gate (red) to source(black) i got 0.673v. source (black) to drain (red) i got .OL drain (black) to source (red) i got 2.184v.

Ah okay! I retested with multimeter in diode mode
Base (red probe) to Emitter (black probe) - 0.674v
Base (red probe) to Collector (black probe - 0.667v
Base (black probe) to Emitter (red probe) - .OL
Base (black probe) to Collector (red probe) - .OL
Collector (red probe) to Emitter (black probe) - .OL
That looks okay. Next step to remove mosfets and retest?Comment

Maybe, i usually check a few times before i write my numbers down. The fuse is definitely blown, in continuity mode there is no beep and OL on both of them. i checked with another fuse further up the board and that one beeps.Comment

by TR103Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
by MgiffuneI have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
by IerwinHello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
by gl4709I am working on a Samsung un55cu7000d which has backlights and audio. There is no picture. This model does NOT have a separate TCON board. Before I order a main board I would like to try and confirm that the issue is not in the display. The ribbon cable from the main board goes directly to the display and I can then disconnect the left from the right. When I disconnect the right side the display lights up on one side but has no video being displayed. Can you all give me some guidance on how to confirm the main board is the issue.
