Logicboard to LCD output problem?
MacBook Pro 15" A1286 Late 2009
Long story short:
-Initial problem: build-in LCD wasn't able to render black, instead flashing green was appearing.
-First Diagnosis: external monitor worked fine. Went to apple store / genius bar, they run their diagnosis and they only detected a battery problem (it has 400 cycles ish / nearly 4 years old) and a RAM problem (I upgraded by a non OEM apple RAM). But nothing with the logic board. Thus we concluded that it has to be the LCD.
-First attempt to solve the problem: I bought a new LCD and replaced it. But the problem still persistent.
Any idea how to solve it:
- Software problem..... ?? I don't think so.
-Logic board problem.....could be, but a new logic board is too expensive. Suggestions?
Thank you very much
