Hi,
This is a previously working Acer laptop
but two months ago it started to show symptom of sudden blank dark display with blue led power and fan still on.
Sometimes it is a blue screen saying i might have changed a hardware, etc...
The whole screen will freeze and i need to press power button to restart. But the same issue of blank display return.
Initially i thought is a heat problem. So i changed to a new thermal fan but the issue is still the same. I also try changing to a different hard disk, reseat the memory card. But the same issue remains. I attached a picture of the motherboard for reference.
On hand i have a dmm, with some basic
soldering skill but i wish to diagnose and repair this laptop if someone is kind enough to guide. Thank you in advance.
