Just opened the screen and saw this: That doesn't look good at all :sad: I guess the only option is to get a replacement screen

Thanks Byrd. I'll check the connector on the LCD to see if it's the issue with that black band :)

This is how my PowerBook 145B screen looks like: From what I've been reading about PowerBook screens I think that all those "weird" lines in the screens and faded parts are due to bad capacitors, am I right? But what about that black part in the top-left side of the screen?? That doesn't...

Last week I got a non-working Powerbook 145b for 20€ (~23USD). The first thing I did was to test the power supply, which was giving a good 7.8V. I saw that the battery was still in place and I feared the worst. When I took it out my suspicions were confirmed: corrosion. It was looking...

Yeah, that looks quite nasty. I wouldn't be surprise if there are broken traces on the board due to that corrosion. Last week I got a 145B looking like that one (or worse) and it had some broken traces:

Just an update on this:   I kept persevering and I got it working! I tried many different things really. I saw that the terminals where the battery gets connected were a bit corroded so I desoldered it to see if there was any damage under it. I couldn't see much but when I put it under the...

Interesting. To be honest I didn't think it was the main boards because they look pristine: I was also worried about the pram battery, but I don't think it can cause that problem, right? hmmm I'll check the main boards better in case I can find something wrong.

it does not make any sound, nope :/  one thing I found weird is: I was checking this iFixit guide and saw that RAM module that mine doesn't have. Is it needed or am I actually missing parts???

So you think the screen or some other part is gone?? :(

Yeah, that ribbon cable seems very fragile... it was the first thing I tested for continuity expecting one of the paths to be broken. But it seems all good. I removed the display from the plastic cover and it's a huge PCB, but no signs of caps in the back. Or do you mean I should remove the...

Hi. Got a Powerbook 180 and it is not showing anything on the screen: I've searched in the forum and I've found this user with the same issue:  I've also read that it may be an issue with bad capacitors and I have seen some people replacing the caps in other Powerbooks of the 100s...

Hey mate, did you fix the display by any chance? I have a Powerbook 180 with the same issues. I tested the ribbon cable for continuity and everything seems fine.
