      Start by measuring voltages on the inductor coils (Vcore, Vram etc)

              Voltage ram is 1.5
              V core is 1 v
              When motherboard is standby voltage bios ic is 3.3 but when I turn on motherboard by connect power pin, ram voltage decrease to 2.8 v..

                  Nintendo Switch Oled HEG-001: Second-Stage Boot Failure
                  by privato89
                  Hello everyone,

                  I'm facing an issue with a HEG-001 motherboard that is unable to complete the Second-Stage Boot. I'd like to start directly with my conclusion, which is the decision to replace the MAX77621AEWI chip, and understand if it could be a correct evaluation.

                  Before I dive into the process that led me to this decision, I want to mention that I have a fully equipped lab where I can perform any kind of tests.

                  Let's begin:

                  Following some guides online, I tried to understand how the Boot phase of the Nintendo Switch works, and what are the...

                  Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                  by cheeky2
                  I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                  Obviously the same LVDS connector for the screen connection...

                  by Dani_2024
                  Hi and thanks in advance for any input you might provide!
                  I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                  Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                  Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                  Xiaomi router freezes at boot after re-capping
                  by hinisa
                  I'm using Xiaomi Router 4A gigabit edition as wireless repeater. It worked fine for 2 years or so, but last week, wireless started to disappear.

                  When I unplug/replug the power, it was working fine for a day/half a day or so until it freezes again.

                  After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:



                  Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during...
