My LG 60PA6500 would turn on automatically when plugging it in. The screen would be backlit but nothing was visible, no menu and you couldnt turn off the tv. I was testing the voltages on the X board I think when I shorted it out. Now nothing happens and all I read is 120Vac at the main board connection.

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... -
Hi
I'm a beginner in laptop repair, a friend of mine gave me his laptop to repair, a Lenovo Yoga 2 13 (20344), he said that when he plug the laptop, he hears a buzzing noise.
I checked, this is a coil next to the cpu. When plugging the laptop, the cpu start getting hot and the coil next to it too and that without even touching the power button.
My guess is that the cpu is simply fried and he can now toss it in the bin.
(I also could not find schematic for this laptop so i will create a thread about it)
Do you have any idea about what it can...
