Hey all,
I'm restoring an A1181 Macbook which was given to me in a state of disrepair. After a thorough clean of the logic board I've got it booting again, all seems well.
However - the screen, while fully operational, seems:
A) A bit dim, and
B) Discoloured - like it's colour balance is all set wrong or something. Yellowish tinge? It does display all colours, red is red, green is green, blue is blue.. just.. tinted.
I have the funds to replace the screen, but if it's another problem I don't want to waste the time, money and energy, so I'm just checking: has anyone heard of this before and if so do you know what the problem is?
I'm reasoning it's just gruesomely faded CCFLs in the display panel because:
- I've never heard of an inverter changing the colour of a display (though it is a bit dim, I've also never heard of an inverter causing a display to be dim, they usually just clap out completely)
- Due to the nature of how LVDS signalling works, any signal loss or connectivity issues between the board and the screen would cause a complete or severe lack of functionality. The screen displays all colours, there's just a tinge to it. Hopefully this rules out the cabling.
- I've never heard of a logic board failure causing the chippery which drives LVDS to misinterpret colours in such a benign and consistent manner. After all, it's all digital, right?
What do you think?? Someone please confirm they fixed this with a new screen!
