      Look at the power supply board connectors to see if there are pin labels printed on the top or the bottom side of the board or not.

              I hope OP at least did the fuse check without giving instruction.

                              The fuse (red square) will check like a short with meter in ohms test (same as meter leads shoted together)
                              If the fuse is ok, connect it back into the tv and check if you have 5VSB. 5 volts dc standby voltage

                                  So I just check it from underneath the board right? If so when I test it nothing happens my meter just stays on OL

                                      Test in diode mode, if you have a meter that beeps when you touch the probes together, if fuse beeps it should be ok, probe on each end of fuse, make sure you have the proper two points on bottom of board.

                                          A common failure seems to be D10 & D11, check them in diode mode to see if they are shorted or not.

                                              Hi all!

                                              I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                                              I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                                              hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

                                              Hi there,

                                              I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.

                                              The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:
                                              ...
                                              Pin out and expected voltages

                                              by sam_sam_sam
                                              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                                              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                                              I checked switching power supply brick 19.2 volts multi meter only

                                              No booting without switching power supply connected

                                              Checked switching power supply with an (28 volt ) incandescent light bulb it lights then hooked up the switching power supply again now the laptop and boots like normal

                                              What the heck is going on here...
