Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
A few days ago my laptop gave me problems, when I wanted to turn it on to my surprise without charging so I did not put much importance on it, after that I turned it on with a charger, it turned on and charged the laptop, the problem with the laptop is that when it is turned off it turns to turn on after seconds, sometimes at 2 or sometimes at 8, other than that it works normally, I already checked many things, I changed a mosfet at the charge input to a pnp but it remained the same, after that I checked and I did not find anything outside Normally, before that, it had a failure where I changed... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down

Hi all! I have a problem with Pioneer VSX-D1011 – it don't turn on when the amplifier is disconnected from the socket for a few minutes. Standby LED doesn't light up. I'm a beginner in electronics, so I'm not very good at reading schematics. I tried to find the visual damages of components but I didn't see anything wrong. All of the fuses are ok, both of the switches the same. Have you any idea where should I start looking for? Once on every 100 tries I am able to turn it on, but what can it depend on? -
Hope this is the right place, someone can help me.
My laptop started having a really strange problem....
When I turn it on the fans start working at a crazy rate and with random breaks...
They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.
The model of the computer:
Xiaomi Notebook Pro X 15 OLED (A30)
