SAMSUNG NP300E5A TURN ON BUT NO IMAGE

Post by jp_jota » Sat May 25, 2019 5:14 pm

Hello my friends, I need your help again. I am trying to repair a samsung np300e5a, which turns on but no picture appears and the fan runs at full speed,
I dont have a schematic for this model and I do not have the boardview, which makes it difficult to identify any component.

I notice also that the 1912a mosfet with 1.060v heats up a lot, And the coil next to it also heats, it replaces it with new and stays the same. if i remove the cpu heat desappers.

3.3v ok
5v ok
19v ok

MODEL: SCALA3-15 / PETRONAS-15 REV 1.5
BA41-01839A PTC

if it is possible someone can help me and facilitate the boardview or schematic of this model. thank you

There are a few possibilities as to what might be wrong with your laptop. The most likely of these possibilities is that your motherboard or " Graphics card " may need to replaced.
