    You have a simple one to replace, here's a video, you can see the board without the cover. you can also check the two capacitors and those other components looks like there's 3 or 4 : https://www.youtube.com/watch?v=-4TMdKEV-uc

        Wow, thanks for finding this video, it shows exactly everything i'm going through with mine, i did test the fuse and mosfets with my multimeter, they checked good, also caps tested fine, i didn't try that trick with the neon lamp shown in the video, but i think my problem will follow the same path, i think i'll try to find that inverterboard and replace, or maybe if i can find that pwm ic as suggested in the video is most likely the bad culprit.

              Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
              by max789
              Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

              I made the following tests:
              1. Disconnected the main board from Power Board = backlight works.
              2. Connected the main board and disconnected the T-Con = backlights does not work.

              So I ordered a main board from Ebay also BN41-02156A but from...

              VIZIO M557-G0: Backlights or ???
              by bpcannan
              'Morning,
              I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.

              Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.

              I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.

              I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate...

              Hello everyone,
              I want to find a replacement for uP0109 8pins, and i found this parts:

              uP0109 is "2A Ultra Low Dropout Linear Regulator"
              RT9199 is "Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator"
              FP6137C is "2A BUS TERMINATION REGULATOR"

              can replace uP0109​ by RT9199 or FP6137C ?

              Samsung UE49MU6400 acts dead until disconnecting backlights, then works.
              by jesterace
              Hi everyone I have this TV which was dead one day when I tried to turn it on. I've had the cover off and there was just a pulsating/electrical clicking/ticking noise from the PSU. I disconnected the mainboard as sometimes this works to just fire it up with backlights on? That didn't help. Same noise. Then I disconnected the backlight cable from the PSU and the TV came alive. It appeared to respond to the remote and i'm pretty sure it's fully operational when there is no backlight connected.

              However, I am in a dilemma.

              I tested the backlight outputs with the lights disconnected...
