A new replacement LCD for Tandy PC-3 & Sharp PC-1250/51/55

Описание: Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://www.pcbway.com/

In this video we fit a new replacement LCD in a Tandy PC-3 which is the same as the Sharp PC-1250/51/55. Thankfully someone is reproducing the LCDs for these vintage pocket computers. (Link further down.)

We’ll try a different method to separate the old LCD glass from the adhesive on the metal frame. We’ll try using a hotplate to soften the glue rather than acetone. Will it work? If so it should save hours of waiting. Join us and see how we made out.

Timeline:
00:00 – Welcome
01:05 – Initial test and tear down
12:23 – Hot plate experiment
15:19 – Aligning new LCD in frame
19:43 – Reassembly
26:01 – Testing
27:02 – Wrap up
