Today has been fun, I got a dead Toshiba Satellite 460CDX for less than a tenner which I'm not even sure covered postage. The seller knew it didn't work, they had stripped out the hard drive and half the screws were gone.
Through the course of today I've taken it from a dead Toshiba Satellite 460CDX that gaves codes 05 & 4C - which according to the Tecra 730CDT maintenance manual, 05H / 05Hex is "SM-RAM Check" and 4C is meaningless i.e. it stopped running meaningful code after reaching post code 05, so a RAM fault...

Back to a working Toshiba Satellite 460CDX: Re: Toshiba 460CDT - POST/Flash codes?
And hopefully that will help mattlacey and anyone else with a Toshiba Satellite 440CDX / 445CDX / 440CDT / 445CDT / 460CDX / 465CDX / 460CDT / 465CDT laptop, four little traces completely broke the computer.
Once it was working, I found out the original screen is not only garbage (DSTN) but also broken:

So for fun and because I've wanted to do this for a while now, I converted it from a 460CDX motherboard that drives that DSTN screen, into one that drives an active matrix TFT - it's a Toshiba Satellite 460CDT now

That line? This is a faulty screen, I'm not gonna do weird electronic tests on a good screen 😁
The mod only requires moving 20-ish 0603 resistors from one spot to another, there's good clearance around them so it's pretty easy to do, gonna detail it in a new thread in a bit. It's much easier and less involved than this previous hackup: Upgrading a Toshiba laptop from DSTN to TFT panel - The Satellite 400CS becomes a 400CDT
(which I made look way worse than it is, you can easily make a 430CDS into a 430CDT by putting the video card + LCD from the 430CDT onto the 430CDS motherboard. Good if you've got a dead 430CDT but a working 430CDS)
