          Samsun ue49ku6450 blinking red light only when press the power button
          by pni
          Hi guys I have this tv Samsung eu49ku6450 that have a problem. When I plug in the power cord the standby led starts to blink but nothing happen. Then the standby led disappear. If I push the power button I see the standby led blinking but nothing happens and if I stop to press the button I don’t have the standby led red…nothing . I don’t understand if there is a problem in the main board or in the power board or it s a firmware problem. I tried to disconnect the main board from the power board, and I know the led should turn on when the main is unplugged but nothing happen…..so could be...

          Microsoft Surface Pro (5th gen) model 1796 - no power
          by PantherDave
          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.

          Consumption : when charger plg in = 0.004 amp

          Only 3/5 vl are present when charger connected..when i put my red probe at the coils of 3/5volts and power on with my power suplly it try to rise than 0v.
          when try to power on using power button i note this starnge value : 3v then 0.300v then 3v !
          No light at power button led

          HP 470 G5 blinking amber light no power
          by huzo
          The board is daox8cmb6eo and i can't find no boardview or schematics on the forum or anywhere...

          So i plug in the charger, amber light starts blinking ,there is 3.3V and 5V present, and 2.4V on the power button,board doesn't turn on, no shorts...
          I've tried flashing the bios...

          interesting thing is the battery was around 7,8V, and it's 11.1V battery, the mosfet near the battery is open, but not charging,i desoldered it,tested it and it's fine ,but the amber light kept going on the charger so i charged the battery with power supply and got it to about 10.5V...

          Lenovo ideapad 3 no power, orange light blinks once when charger inserted
          by roxboy1984
          Hi guys,

          I wonder if anyone has encountered this. I have a Lenovo ideapad 3 that shows no signs of life except when the charger is first inserted the orange charge light comes on for a brief second and then goes off. There is no other sign of life and no fans or lights come on.

          if I check the voltage going to the battery it spikes when I insert the charger and then hoes back down.

          i tried injecting 2V but nothing gets hot. Any ideas? Im still a noob.
