      Shopjimmy and norcal75 have better videos and better warning.

            Listen to what he said!

            "I re-read my thread, all you really did was insult me," https://www.badcaps.net/forum/showthread.php?t=67776
            It took 12 posts to get you to set the meter properly.
            And you told me my voltage on the connector couldn't be right, in fact you said it was impossible, BUT it was right. So I was measuring different parts of the board and forgot to adjust my meter, big deal.

                  You should know how to read your meter by now.
                  As I indicated, now way you can have 0VDC on the main filter cap, operator error.
                  Lol, I forget things faster than I learn them, meter was at 20 will try higher setting. board is bn44-00340b.

                    Same instruction as not to touch anything in the deadly hot side of the circuit with your hands or your body, proper instruction is important.

                            At this point test the Voltages on that balancer board diode as shown in the Video, you will have to turn the TV off and on when you move to the each next diode.
                            " and 13.16 from pin 7" That MUST BE AN ERROR on your part because it only has 12V supply to run the comparator circuit on that balancer board so no way you can have 13.16V.
                            Look at your meter to see exactly what it is showing on your meter display, more likely it is 13.16mV, recheck your reading. It is VERY IMPORTANT to get correct data! V and mV are not the same.

                                  Well, the 12 supply feeding the comparator circuit and you get 13V out off the circuit that has no Voltage booster but just a simple IC comparator circuit, then I do not know what to tell you.
                                  Do you know what LD pin is? that pin is normally HIGH >11VDC, it will go low when it detects bad lamp which what you have, that low is an error signal to tell the inverter circuit and the main board to shutdown the inverter circuit, that signal must have gone low otherwise your backlights would not have gone off due to error detect. That is the reason why i suspect it to be in mV range not in the V range as you report. You can also see the block diagram and explanation on how the comparator works in that Balancer board which is explain in that SONY trainning manual I provided.
                                  BTW, those Voltages you test on the those diodes are fed into the comparator circuit.

                                    I need to get a new multimeter. Maybe you guys could argue in another thread?

                                      @nomoresonys budm was pointing out an error in the video which could have bad consequences to anyone following his verbal instruction. Not sure how you could take that personally. My guess would be if you told tampatec about the error he would thank you for pointing it out and add a correction to the video.

                                      @OP, was this set wall mounted ? If the solder joints are ok at the ac power in then it's possible your power cable is needing to be replaced. I ask if it was wall mounted to see if it's possible the cable was kinked against the wall behind it.

                                          Ok, it may have been a verbal error but he set his meter properly and it wasn't just one rude response. it's over now tho. everyone has their own style and good for them, I like to try to help without making people feel stupid or being OVERLY SARCASTIC but that's just me.

                                            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.

                                            Hi all,

                                            TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                                            I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                                            A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                                            When powered on, initial splash screen (HISENSE ANDROID TV) displays for a few seconds then power shuts off. Tried updating firmware with USB flash drive (can't find 4GB drive but did format larger drive in FAT32) with no luck. Flash drive would be accessed but would never get to the update process. I have ordered a board (RSAG7.820.7911/ROH, PART# 242585) from eBay which will arrive in a few days. Does anyone have any input of whether I am chasing down the right trail or should I be trying something else? I appreciate your time and wish to say thank...

                                            Original NES power issues
                                            by sli4
                                            I recently turned on my old NES to find the red light won't go on at all. When powered on it shows black bars on the tv and a loud buzz through the tv speakers. Powering it off, the buzz goes away and tv goes back to normal (white snow).

                                            I tested the power supply itself and it is outputting 9V as it should - first two solder joints on the board at the power port show the same.

                                            Here's where it starts getting funky - When powered on, one side of the 7805 voltage regulator is showing 18V and the other is about 8.7V (center 0).

                                            On the big blue connector I get...
