MacBook Pro display doesn't work

I have the same problem with my 2.4 Ghz MBP. I am in the process of transferring data into my Powerbook with the MBP in target mode connected by firewire, and it is working although I see nothing on the MBP display. I am thinking of getting a cheap exterior display meanwhile until I have time to have the MBP serviced. Either way most of my data at least will be preserved in case they have to wipe the HD. Let me know what you find out. I did the command, option, P, R thing to no avail. The MBP works, just nothing on it's internal display.

Mine is working now! I used the DVI adapter to plug it into a DELL PC display at my job. The DELL display did not come on but the laptop display did! Try it, perhaps it will work for you. One of the telltale signs was when the MBP display was not working the sleep light remained on; not pulsating but steady. Now it is off and the laptop seems to be working fine. Hope this helps.

Try resetting the PRAM...I was having problems with my MBP display not lighting
after being closed for a while and then opened...this seemed to work for now:

Good luck!

I am going to chime in because I had the problem, did an archive and install which fixed the display problem but a display issue is back again! When I did the Archive and Install, I purposefully did NOT install the graphics update. That fixed the issue until yesterday...... I think the monitors worked alright when I started up in the morning but later in the day, I noticed that the external monitor (SyncMaster225BW) was a yellowish color and the letters were distorted. Ok, so I unplugged it and previously when I unplugged it (since the Archive and Install anyway), the MBP display would go blue but come right back on. Not so yesterday. It stayed blue so I had to press the power button to get it to go off. Booted up and came on. Plugged the external monitor in (can't remember if I plugged it in while it was shut down or after) and it worked fine. Booted up this morning and the resolution and color on both monitors was yellowish and not right. In fact "mirroring" was turned on, something that I did not choose. Recalibrated my MBP monitor. Got that right. Oh, and yesterday and today, I had to choose my background pictures for both monitors. Couldn't get the external monitor to work right so unplugged it which caused the MBP monitor to go blue and stay blue. Had to reboot again. Left the external monitor unplugged. Started writing this post and plugged in the external monitor again and all is right. Both have the correct background picture and resolution and in the menu bar, both are listed with the correct names (first thing this morning they weren't named Color LCD and SyncMaster). So anyway, that is my display woes. I was so happy that all was well after doing the Archive and Install and not doing the graphics update but something else is going on now. Not sure what. Hope this issue gets fixed soon! Please Apple....... Judy

My problem returned. The sleep light remained on with no pulsing light and no display. I took it in. Bad logic board. They estimate 10 days to fix it.

I didn't know the warranty extension costs $349 for Macbook Pros. Well, I may wait till my 1 year warranty almost expires in June before biting the bullet...I am delaying because I may want to sell it and get an upgraded MBP or something else. Since my Powerbook still works fine I may consider a (cough) Windows unit, but dread the thought of Vista...
