Secondhand Replacement Screen for Toshiba Chromebook 2 (CB35-B3340)

Once I discovered the support window for a Toshiba Chromebook 2 (CB35-B3340) extended longer than I had originally anticipated, I was more willing to spend money to bring it back to working condition. While I was shopping for a replacement screen earlier I saw several offers for new units and a few scattered offers for secondhand units. I presume these were salvaged from retired machines and resold, which is fine by me as it came at a significant discount. $47 with taxes and shipping (*), as compared to $75 (before taxes & shipping) for a new unit.

That ~40% discount also came with a caveat: I clicked “Buy” on a unit that was rated “Grade B: Fully functional but with visible blemishes.” It was a bit of a gamble, but my primary requirement is only to see enough to enter developer mode, so I decided I would tolerate visual blemishes to save a few extra dollars. There was also a bit of a gamble in shipping. from my disassembly efforts I knew this panel is very thin and fragile. This time around, I did not mind the extensive packaging of Amazon orders.

I saw no physical blemishes on the panel during installation. Once installed, I was happy to see Chrome OS boot up and run. I had to work hard to see the visual blemishes that earned this panel its Grade B rating. I had to set the screen to full black, and artificially increase contrast in a photo editor, before we can see the magenta smudges: Two light horizontal smudges, and two dots one of which look a bit smeared.

I’m not familiar with failure mode of LCD display modules so I have no idea what’s going on here. Perhaps these were manufacturing defects? In any case, these flaws are only visible if I strain to look for them and there is no physical damage to the screen so I’m satisfied with my purchase.

The visual blemishes are not at all bothersome in normal usage. This level of performance was more than good enough to be used as a normal Chromebook if I wanted to use it as such. But the reason I got the screen was to access Chrome OS recovery menu to enter developer mode, so I will try that first.
