    Toshiba Satellite L655D-S5148 Power light on, but won't start

    Hey everyone! I am having some trouble with my Toshiba laptop after 4 years of use. Before my computer died, i had a lot of over-heating issues which started about 3 months ago or so. Every month i had to re-apply thermal paste in order for me not to shutdown during computer games(WoW,LoL,etc). Two days ago, right after applying new thermal paste i tried to turn it back on, but my computer did not turn back on. I think the board may at least be partially alive because the power light comes on and if the battery is in it will charge.

    I have tried looking for the schematics online, but i could not find it. I know my power jack is fine because it reads the 19v. I am just not sure what to do now... I will end up getting a new laptop, but i would like to revive this one from it's shallow state. If anyone can toss me any ideas they will be appreciated! Thanks =)

      i get this a lot on youtube.
      after cleaning it wont work again.
      so!
      how many sticks of memory?
      did you screw back the cpu?
      lcd connector its ok? no pins bend?
      try to do the steps backwards
      Just cook it! It's already broken.

          Hey thanks for replying. I have two sticks of memory, the LCD pins seem fine, and the CPU is screwed in. I also forgot to mention this: As soon as I plug my laptop in I can hear a soft hum coming from the motherboard and the hum changes a bit when I hit the power button. I'm not sure if that's common, but thought I'd note that.

          I will re-do those steps to see if I missed anything.

                      Yes the hum is still there with the CPU and ram out.

                              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.

                              Toshiba Satellite C50-A won't power down
                              by ju123
                              Hi guys,

                              So, I've been racking my brains on this one.

                              I have a Satellite C50-A which I'm repairing for a friend.

                              I recently replaced the main board due to failure.

                              Following this, absolutely everything works perfectly, except for the fact it won't power down.

                              Initially, shutting down via Windows would shut the OS down, screen would turn off (noticed the lighter black go to what looks like the darker black powered off screen as though the backlights have powered off), however the laptop was still running internally with a spinning...

                              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...

                              LG 39ln540v - red light flashes twice, no power to LED driver?
                              by russpall
                              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
