Hisense H60N5705 installed in a conference room, turns off automatically a few minutes after being switched on.
Problem occurred suddenly, during a video conference. Switched on again by the remote control, it continued to work for a while and then switched off again.
Power cable and HDMI cable checked.
No changes by connecting the TV to another source but, even if it is left on the OSD menu, it stays on for a few minutes and then switches off.
So they took the TV (a 60' which is not easy to handle) to the lab and asked me to check it.

Hello everybody,
I got HP ProBook 455 G7 which originally turned on partially(fans on 100%) and hen off after 8 seconds, with AC diode flashing orange and last flash white. This behaviour stayed for a while, but before I realised that there is power delivery issue and not BIOS problem, laptop started to automatically turn on after 2 seconds when in turned off, kept power cycling. So after I fixed shorted cap and burned ferrite bead, laptop turned on fine and booted to windows.
Now, laptop can be turned off and it stays like that... unless you plug adapter again, which triggers... -
My Samsung UE40F6340, which I only use occasionally, has recently started turning itself off. It can take a few seconds to a few minutes before it happens. I've checked the auto sleep settings and similar options and found that none of them are enabled. I also unplugged all connected devices, but that didn't change anything. Of course, I also tried a different power outlet, which didn't help either.
After that, I opened the TV to see if there was any apparent defect, but found nothing. Pictures are attached. Then I disconnected the cable between the power board (right side) and the receiver... -

Greetings!
I'm trying to fix this Asus X540UP motherboard and I can't locate the problem. Initially, the board went dead. I assumed it could be some caps or mosfets. But then when I checked it under a thermal cam the CPU is warming up around 35 to 40 celcius. The 19v is present at locations specified by the boardview. 3.3, 3.2, 1.2, 5 & 12 is present. Only the GPU is dead cold. The board is divided into 3 sections. The middle section where the CPU and GPU are located show shorted power supplies (mosfets, inductors, big round caps). I reflowed both GPU & CPU thinking that...
