    Re: Dead digihome tv

    There are 3 boards on the back. Power board, av main board and at the bottom left I think is the t con board. The wires heading to the bottom right is for the remote sensor and standby light. Plus 2 speakers. Are the voltages ok in previous post?

      thanks for the pictures i have just read another thread and the voltages seem too match yours so yes i think you do have a faulty mainboard .

            Re: Dead digihome tv

            can you retest the voltages on cn4 connector test the outer row of pins 3,5,7,9,11 all boards connected tv switched on multi meter dc volts black probe tv chassis if you still have you old power supply maybe test both supplies.
            Budm if you have a minute can you have a read through this thread do you think its a main board fault? thanks.

                Your old power supply should be ok, if both boards read the same voltages you could re sell one of them and get some money back towards the main board or just keep as a spare of course.

                  Re: Dead digihome tv

                  Sorry for late reply. I've tested with all boards and components connected but power and av board are off the chassis ( I can't test all pins with boards fitted)
                  Following pins have voltage only the rest are zero v
                  Pin 14 12v
                  Pin 12 12v
                  Pin 10 12v
                  Pin 13 12v
                  Pin 11 12v

                        I've uploaded the flash for this mainboard in the eeprom thread. It'll work in this model. Same panel except NO1. Won't matter though.

                            Thanks for the replys. I'm just waiting on a replacement main board. Once fitted I'll update the thread.

                              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                              by Tynan Dill
                              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                              Upon bringing it home and plugging it up, it showed a standby light.

                              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                              The screen seems to blackout and stay black, but with a flashlight I can see the display.

                              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                              Yoga3 Pro-1370 Board NM-A321 DEAD no power at all
                              by k370
                              Hi everyone,

                              I have a NM-A321 board that is dead, with no power at all.

                              When I received the laptop, the +5VPMIC line was shorted. Removing the PU3 (ISL95905) solved the short, so I ordered and replaced the ISL.

                              With the new ISL, the short is gone, but still no voltages at all. I measured the following rails:
                              • +3VALW
                              • +5VAUX
                              • 1.2VSUS_PWRGD
                              • 3VALW_PGD
                              • 1.05VAUX_PWRGD

                              Additionally, the ISL95906 (PU3) is not getting any voltage on the VIN rail.

                              The only place on the board where I find any voltage is on the first MOSFETs, specifically:...

                              • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                              • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                              by corrize
                              Hello, the DSLR has heavyly fallen. It is dead : no sign of life and display nothing.

                              When it worked, it always displayed a card present state on LCD display, even when the battery is empty it display a empty battery symbol.
                              I found a dead fuse, I replaced it and a mosfet burnt, I changed it and another fuse burned. Nothing burned after. And I can't find any short circuit anywhere, it's weird.

                              Now, I try to understand how it works.

                              There is two boards (the little one on pictures has no component) : the first is a « power board » : managing...

                              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                              by Asraf Atb
                              Hi everyone,

                              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
