Many PC-3 and PC-125x pocket computers suffer from LCD degradation to the point where they are no longer useful. Apparently the seal around the LCD was of poor quality, and over the years moisture gets in and ruins the liquid crystal. The result is a display ranging from a few splotches to complete failure.
I decided that it was important to bring all these dead PC-3 and PC-125x computers back to life by reverse-engineering the LCD and remanufacturing them.
These LCDs were custom manufactured by Sharp for the PC-125x. Radio Shack had a rebranding agreement with Sharp, and named the computer the TRS-80 PC-3. Replacement LCDs were never available, and finding a working LCD is problematic, given the systematic failure of the seal.
I tried as much as possible to make the fonts and positions used for the indicators as identical to the original as possible.
I've made a video showing how to replace one of these LCDs. There are a few crucial things you have to be aware of:

I ship via the United States Postal Service, every Monday (US Pacific time) except on USPS holidays, when I ship on the next open day. US destinations usually take a few days after that, EU/JP about 2 weeks, and South and Central American destinations can take up to 6 weeks.
I CANNOT SHIP TO THE UK. Too many packages to the UK have been tracked as ENTERING THE UK, but after that the package disappears. Because of the unusually low rate of successful delivery, I no longer ship to the UK. You can find a parcel forwarder in the US. They will give you a US address to ship to, and then they will send your package from there to you using a reliable mail service.
I CANNOT SHIP TO BRAZIL. Too many packages to Brazil have been tracked as ENTERING BRAZIL, but after that the package disappears. Because of the unusually low rate of successful delivery, I no longer ship to Brazil. You can find a parcel forwarder in the US. They will give you a US address to ship to, and then they will send your package from there to you using a reliable mail service.
