monitor with no image, bad logic board!
Hello,
I have a Macbook A1181 13 2.0GHz with a non working monitor,
after power-on i get a half second flash light from the lcd and from the led light web-camera
and i cant see any image at all (no faint images or back light) from the monitor
i already replace the inverter, still the same symptoms
i think it is the logic board
after make some tests with a voltimeter on the cable from logic board that goes on inverter i can see the same symptoms on the voltimeter (the voltage go high for half a second)
i don´t have a video rgb cable to hook the computer to a external monitor
here my targets:
- it is a bad inverter cable?
- it is a bad logic board?
- it is a smd fuse on logic board?
- it is a Missing enable voltage from motherboard's video chip?
My last option is to replace the logic board
but before i want to try to fix my self
tanks every one
Update
Tanks for your answer.
This model don´t have a nvidia gpu
Components already tested:
- Monitor LCD: OK
- Inverter: OK
- Cables: ???
- Mainboard: ???
»»I am now hunting for SMDs dead Fuses...
Note: the macbook start normally i just don´t have image on the monitor.

Any way, its a shame that i have to replace a complete mainboard
because of a internal malfunction component or because a little SMD fuse that i can't identify,
the real problem here is to isolate a faulty component...
Tanks.
Es esta una buena pregunta?
