PowerBook 520 screen question
Posted by: -_- JC on 2025-06-17 06:52:19
Last year I think I got the best deal of a lifetime on FB marketplace, found a PowerBook 520 for $15 in near perfect condition. It came with the power supply, a working hard drive, and no cracked, or even scratched plastics for that matter. I don't think I'll ever get this good of a deal again.

About a week ago, I finally managed to order a new screen for it, as the only imperfection with the PowerBook was a faulty screen. I managed to get a screen used in the PowerBook 540c, the Toshiba LTM09C017. I found out today while plugging in the new screen that it required a new screen to board interconnect cable, as the old cable was made for a greyscale screen. However, the only cable I found was for a Sharp LQ94D041.

My question to anyone who's familiar with these laptops and more specifically the displays that go in them is, will the Sharp cable work with the Toshiba display, or will I have to hunt for a new cable or display?

I can find a new Sharp display, there's several on eBay. However, there was only one of these interconnect cables on there, so I'm guessing It'll be a long time before I'll find one that matches the Toshiba display.

If they don't work, would anyone out there be able to sell me that very specific cable from a parts machine?

Would really love the community's support, thanks.

The cable is specific to each screen type and manufacturer, so you will need a Toshiba TFT cable in order to use that screen.

Where can I get one?

Out of a PowerBook 540c with a Toshiba screen.

Seriously, even in 1994 you weren't going to be able to just go get one at Radio Shack or whatever. They're application-specific and over 30 years old at this point. I haven't seen any Kickstarters to make new ones yet. Your only option is cannibalization, but given how many of these machines have turned to dust, they're not impossible to find.

I actually do have a spare Toshiba TFT cable but shipping to Canada may be a bit of a pain.

I've previously shipped a couple of items to Canada, and if you get the right person at the Fedex store (or wherever) its only a few minutes longer to send it off, than to somewhere in the US. I recall that a correct description of the item was key.
