Black screen on startup

[Hittmo]

Hello.

I have a lenovo v155-15api laptop.

When i press the power button the cpu fan starts charger led is working. But power button flashes and screen isnt turning on. Anny suggestions?

 

Ive opend the laptop and dissasembled and re assembled everything from screen connector, ram, battery, cmos battery, m.2 ssd. Every single cable and component has been disconnected an reconnected. Evend the screen has been taken apart. 

Have also tried hdmi cable to antother screen.

What kind of initial sign or trouble with the laptop did you get before you went taking it all apart? 

 

Gotta imagine you can also look up that model and find what that charging light blinking means if it is failing POST. It can help you start troubleshooting without making it any more of a wild goose chase

Bro the easy fix is to not unplug and tear  every piece apart tryna Find how to start solving the problem or even identifying the problems at fault

 

All good and fair if it's a freebie I suppose.

Hi Hittmo, apologies for picking up your old thread, but I've got exactly same laptop with exactly the same issue. And I'm just wondering if you managed to sort the problem. Thanks in advance!
