I got my screen from a Thinkpad T61p and it is a Samsung LTN15U2-L05. I just wanted to point that out.
Yup, I had seen your earlier post about this (thanks for that) - the T61p uses both Samsung and LG panels. Of the LG panels, though, the model the T61p uses appears to be the LP154WU1-TLB1 (which is what I meant - sorry it wasn't clear).
And just for an update. I'm still having a few issues. I was one of the guys that just got it to work. Using what I guess I coined as the "sleep method." I plugged the panel in with the computer in sleep mode and connected to an external monitor. When I unplugged the external monitor in mirror mode and the laptop refreshed the internal panel and it was showing correct colors in1920x1200.
I believe I came up with the 'sleep method' originally (as a rather last-ditch effort, as I wasn't sure some electronics might get fried). Since I've installed my screen (-04 Samsung) I have had the inner panel stop working twice, I think both times after I shut the lid to go into sleep mode rather than use the 'Sleep' menu item (both times an external was also connected - I believe closing the lid only makes the inner panel stop working on my machine when an external is connected, but I haven't tested this). The first time I used the 'sleep method' to fix it. The second time I tried 'Detect Displays' from inside the System Preferences and that did the trick. So if you're ever in need, try that first, as it's a lot easier ;-)
These are the issues I have.
- Cannot sleep in Windows. When the computer comes back up the colors are messed up. (there has been plenty of people talk about the messed up colors before but I don't know what to call it.)
- Some videos on some web sites show in the messed up colors under windows. Specifically the live video feeds on CNNs site if you want to check with yours. This one is really strange to me.
- Occasionally the computer heats up a lot. The fan cranks up really high and it eventually cools. I didn't use the computer with the original screen long enough to know if this is normal but it seems like it shouldn't be.
I am having worse issues that this with my revision -04 Samsung panel (which appears to meet with widespread success elsewhere). Though it was easy enough to get the panel to display something, I have to use a screen refresh of 50Hz to get good colours (and no shimmer) in Mac OS (at that refresh it seems to be perfect, but it's progressively worse at higher refresh rates), and I've never got it to work without funky colours in Bootcamp (I use VMWare Fusion now so I'm not bothered). And I had to use the 'sleep method' to get the panel working in the first place. I don't know if anyone else has had to do this with this particular panel - apparently most have not. It's odd the way some panel and machine combos act differently for different people (one of the hurdles of making a guide).
Incidentally, when I was first trying to get the panel to work I had to fiddle around a lot, and made a fair number of those 'plug in LVDS cable while Mac is in sleep mode then bring out of sleep mode' fixes. After a while my inverter died and I had to get a new one. I'm not sure whether it was this that caused the inverter to give out (it made a buzzing noise at every brightness level below maximum, something that is not an issue with the replacement I got, so it may have been faulty from the start) but it might be a warning to those fiddling a lot with the screen. If your screen suddenly goes completely dark, try replacing the inverter.
(By the way, for whomever is making the guide - it might be a good idea to make it "wiki" based, or as nearly wiki-like as you can make it (i.e. revisable in some way by the user community) so that everyone's experiences can be taken into account.)
Apart from that, everything is fine - it's all reliable enough for me to have taken the thing with me on a month long road trip without issues.
Other than the fact that this panel is nowhere near as bright as the original everything else works good. I'd like to find out what panels may be as bright as the original to find a better option to use than this one. Any input would be great.
The revision -04 Samsung screen is also not as bright, and there is more 'ghosting' (a lower pixel response rate). I think the LG panel is as close to the original specification in terms of brightness and response rate as anyone can get - which is why (and some others) are interested in seeing if we can make it work. (The Thinkpad user community seems to be pretty happy with that panel, as well.) Someone reported way back (before Leopard) that they didn't get it to work, but now that Leopard is out and seems to be much more custom-panel friendly, it seems like it might be a good idea to try again.
