I've been complaining for a while that the display on my A1138 Powerbook(DLSD, HR) is very dim. As this is one of my most used PowerPC Laptops, this is bothersome to me. A while back, a very generous MacRumors member offered a couple of Powerbook and iBook parts for the cost of shipping, and those have been gradually trickling in here. Among the parts was a "stripped" A1138 with the panel still attached. The computer still has the logic board, although as best as I can tell is pretty much dead. I put a stick of RAM in it, connected a top case, and plugged it in. I'd hoped that I could at least some sort of gray screen so that I could see what the panel looked like. Unfortunately, it won't progress past spinning the fans-I don't get a boot chime or any other signs of life. I'm not posting out of interest in getting that one going, as it's missing a lot of parts and I don't think is worth the effort. Rather, I'd like to transplant the panel to my good A1138. Looking at iFixit, it appears to be an involved enough job that I'd prefer to not blindly switch them without ensuring that I'm actually going to be upgrading the one in there(I'd hate to find that the replacement has liens or pressure marks). So, I guess what I'm wonder is-does anyone know of a way to test the panel without actually installing it in a good computer? I don't mind to pull the donor panel out(and in fact would do so anyway before removing the one on my "good" computer) but am lost at where to go beyond there other than just plugging it into my good computer and trying it out. Does anyone have any suggestions?
