Macbook Pro display difficulties

    I've had an unusual problem with the display on my Macbook Pro, which I bought in June 2008. Maybe someone on here could enlighten me as to what happened!

    On Sunday, the screen went dead, but it booted up fine judging by the start up sound. Took it to a repair place and they ran a test for a known issue with the NVIDIA graphics card which can cause that problem, but it didn't turn out to be that. Later, they rang back and said it needed a new display and quoted me €600. I said okay, because it's a good machine and I just wanted it back! They ordered the parts and said they'd get back to me.

    This morning they rang and said it was actually an issue with the Logic Board and I would need a new one, which would cost about €700. They said it worked running off an external monitor though, so I figured I'd just buy an external and run off that for the time being. So I picked up the laptop, paid €70 for their diagnosis fee, and went and bought a monitor instead (much cheaper!).

    Took it home, hooked it up. Closed the lid just as it was booting up which forced the display to the external, then opened the lid so I could type in the password. This all went fine and I was happy as I could use my laptop again, if only in this slightly restrictive manner! Then I decided to adjust the display settings for the external display in System Preferences, as they seemed a bit 'off' to me.

    I hit 'detect displays' in the 'displays' tab, then suddenly the laptop screen came back to life! I then had a dual screen setup, which was cool. I then shut down the laptop and restarted it without the external display and it still runs fine. Which is great.

    But my question is, what happened?? Makes no sense to me. The guys in the repair shop were about to replace the whole logic board, and now it's fine. I'm worried it's an intermittent problem which could happen again.

    The log on the receipt I have says it was an issue with 'a MLB or LVDS connector' which Google tells me are logic board components but I know little more than that.

    So, should I be worried that this will keep happening? Also, should I ask for my €70 back as their diagnosis was incorrect? Any insights would be greatly appreciated!

    sounds like the Nvidia problem to me... I know this test is not totally conclusive and can pass and fail in the same day. Especially for a machine that has just exhibited the symptoms.

    Apple have an extended warranty program me for any of the models affected by the failing nvidia chpset, You need to call them ASAP to see if you're model is covered as this sounds like the start of the end for the logic board if it has the NVidia chip,

    Hey, cheers for the reply. Took it back to where I had brought it and seems to be sorted now, they got it to fail the diagnostic test for the nVidia problem. The card and logic board have been replaced at no cost to myself. Well I'm typing on it right now anyway! I'm a bit concerned that it will only happen again as from what I'm reading online all those cards are apparently liable to fail. Crazy that I've had this Mac nearly four years and heard nothing of this issue. Will just take it as it comes I suppose.
