    Technika LCD32-407B Shuts off after 40 mins.

    Friend brought this round asking me to take a look, she said it turns off after 40 minutes and wont switch back on for a while.

    I opened it up and found 2 bloated caps 1 of which was beginning to leak.

    Replaced them and it has now been on non stop for 4 hours.

    This is just in case someone has a similar problem.

    Nice easy fix, what caps did you use as replacements? Would recommend replacing all of the similar green Samxons, known bad caps.

          Samsung PN43E450A1FXZA (Plasma) - Display up for 4 mins, then shuts itself down
          by berriferous
          Set was manufactured in 2012. I'm trying to diagnose where the problem is. I am assuming it is over-currenting after heating up? Display looks fine until it decides to shutdown. If I keep turning it on, it will eventually refuse to power up and requires unplugging to get it to respond again.

          I originally thought there would be some easily detected bad electrolytic capacitors, but I don't see the telltale signs. There might be some very minimal bulging on one of the x buffer board. BN96-22092A (LJ92-01852A).

          If I unplug the power feed to the X/Y board (LJ92-01854B), the...

          Asrock z97x starts then shuts off after 4 seconds, sometimes more, no post
          by chaos-theory
          I have a really weird problem, this motherboard was working normally, someday it just started and all fans were running but didn't want to post, tried resetting bios, checking CPU and it was getting warm tried external gpu, flashed bios with programmer, but same problem.
          Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...

          A1706 820-00239 - Works, but sometimes shuts off when the charger is disconnected
          by baglaivlad
          Hello everybody!

          Have in work A1706 820-00239 model. Originally no power, shorted PPBUS_G3H because of corroded C6403, C6404. Some water damage around this components, but nothing major.

          After replacing this capacitors the laptop came back to work, I reinstalled MacOS and had no issues until I started to test Type-C ports. Sometimes the laptop shuts off immediately when some action with Type-C ports performed (charger disconnected or USB device inserted/disconnected). I checked Type-C port flexes, they are okay, but I cleaned them anyway. I can't see any signs of liquid...

          Dell inspiron 15 7567 sudden shuts down
          by samuelphirik
          Hi. I have a pre-owned Dell Inspiron 15 7567. It worked fine
          During the first 3 days of owning it until Dell Update software popped a notification about a latest Bios version 1.15.0 and latest Intel ME Software update of which I updated. It rebooted and firstly, Upgraded Bios from version 1.8.1 to 1.15.0 then it started upgrading Intel ME firmware. After that update, my laptop shuts down without notice (Like thermal shutdown)
          I checked Thermal Paste on the processor and the Graphics Chip and it was dry. Replacing thermal paste has not helped me.
          Now I've noticed that laptop...
