I have also seen similar lines on my screen, though only in a small corner. As of now, my MBP is still running.
I have just been talking with my brother who also has a MBP from early 2007 and he has reported seeing the same lines across his entire screen and now his MBP will not startup beyond the grey Apple screen (similar to your attached photo).
Any help out there?!
"Kaput" could apply to the video chipset if you have the NVIDEA 8600M GT. See:
If System Profiler identifies your computer as a "MacBookPro3,1" or "MacBookPro4,1" AND the computer fails a special test at an Apple Store or AASP, Apple with replace the logic board for up to four years from date of purchase.
Things to check:
1) If the defects repeat on an external monitor, the chipset has probably failed.
2) In System Profiler, click "Graphics/Displays" in the left-hand "Contents" pane. In the main pane, find the line that starts with "PCIe Lane Width:" If that value is anything other than "x16" the chipset has probably failed.
If the number in the model identifier is less than 3,1 the computer does not qualify for the free fix (which is a new logic board). Older MBPs with ATI Mobility X1600 chipsets have failed, but you are on your own.
I'm not able to start the computer up at all, so I can't check the system profiler, but I did check my receipt, and I purchased my MBP in April of 2007—which, thankfully, is still in the four year window for a couple months. I'm going to take it to the Apple store, and hopefully the problem is fixable. I'll report back when I know for sure. Thanks SO much for your help!
Okay, I got the MBP started up (zapped the PRAM; seemed to stabilize it). It was purchased within four years (April 2007). Regarding the specific things you mentioned:
-The PCIe Lane Width value is x16.
-The chipset is ATI Radeon x1600.
-The Model Identifier is MacBookPro2,2.
And that's less than 3,1. Does this mean I'm out of luck, and it's not even worth taking into an Apple store?

Out of luck for the LB replacement. The X1600 is not covered.
You can however, request a "Depot Repair." Instead of fixing the computer in the store, they send it to a central refurbishing facility and, assuming the case and display are not physically damaged (no beer stains, hair balls, or tire tracks), they rebuild it for a flat fee of about US$315 (shipping and tax may apply.
Everyone whose has taken this option (and reported back here) were pleased with the outcome. Turnaround is about a week.
I wanted to report back to everyone on this issue. I'm actually typing this message up on my MacBook Pro as we speak. I had a Genius Bar appointment on Thursday of last week, sent my MacBook Pro off for the flat rate repair (which is, as was stated, about $315), and they replaced the motherboard (which turned out to be the problem). My MBP came back this morning, and it's running even faster than it was before! Given that my options were doing this, doing nothing or buying a new laptop, I'm quite pleased with the results. Thanks so much for suggesting it, Allan!
Well, good for you David, but I still think you have paid too much. The problem with your MBP was most probably a heat related desoldering problem of the ATI X 1600 GPU, an issue Apple knows about and still doesn't seem to want to acknowledge.
Nvidia took the responsability for their delaminating Geforce 8600 M GTs in (a.o.) the MBP Core 2 DUOs, so the extended warranty program probably didn't cost Apple a cent. And the program has recently been extended from 3 to 4 years from date of purchase, just to show you!
ATI X 1600s are fine, but Apple seems to have used a faulty thermal design for them with the MBP Core Duos, even underclocking them because they probably knew someting was fishy in the first place. Just stick to your release dates, even if you know you have a major problem! What is more, in this first MBP model, many cases of too thickly and unevenIy applied thermal paste eventually going brittle have been documented. In which case instating a recall program would cost them big time. So they are simply in denial this time!
This defect actually calls for class action, but unfortunately the MBP in question is by now obsolete, so who cares? Probably I'll go the DIY way and reflow the bugger myself. Shame on you, Apple!
