White screen, but works fine with an external monitor.
My A1226 MacBook Pro display screen went white when i pulled out the power cord one day and has not worked since.
It works fine with an external monitor and the screen brightness keys make the display brighter and dimmer as expected.
It shuts down when i press power then enter (dont know if this is relevant thought i read somewhere it maybe)
i have just changed the display data cable, but still have the same fault.
I don't know if i want to buy a new screen if it will not fix it. Is there some other test i can do to determine the fault?
Thanks!
Is this a good question?

Have you checked your LVDS connector? Check the pins on it and take a look to make sure that none is missing or shortening it out. Obviously the backlight works, that is what provides you with the white light, but you are not getting any video signal.

OT, I was thinking the same thing but he pulled the power cord when it happened which got me thinking SMC and/or the loss of PRAM power. He did replace the cable which could have introduced a new problem too.

Hi , this turned out to be the logic board , the guy i got the spare parts off
to try said he would put money on it being the logic board , and he took all the
parts I didn't need back , very helpful chap.
I'm sure I read somewhere that
there is a fuse on the logic board for the display , I would like to repair my
board if possible as it was an upgraded board (invidia issue) and also a 2.6 ghz
the replacement I got was 2.2 . .
Any idea where this fuse is ?
Thanks

Greetings! Same thing is happening to my A1226. Screen goes white. I changed one of the the screen cables that connects on the logic board and after it worked fine. Recently, it did it again. I closed and opened the lid and it came back to normal. So, I am going to check the other two cables that connect on the i/O board the blue and the black one. Also will check the inverter board with cable too.
