Great unit that fixed my pocket computer. Was not too hard to install using the developers install instructions.

Fantastic product

For LCD replacement for TRS-80 PC-1 / Sharp PC-1211

So grateful to the creator of the replacement screen!
Quality of the product is fantastic, and instructions on replacement are very clear.
I decided to try installing it without cleaning neither the new display nor the elastomeric strips, just kept them clean. Everything works fine.
When I tried to adjust the glued potentiometer to improve contrast, it snapped and suddenly the device appeared dead. I replaced the potentiometer with a 220kOhm resistor (my first guess) and it worked great right away. Important note: I'm using THREE silver oxide batteries to keep the voltage close to the original four mercury batteries. The fourth (left-most) battery apartment I've shorted by a flipped battery.

The new display looks and works fantastic, it's better than I imagined. Kudos to the author!

Amazing work, thank you a lot

For LCD replacement for TRS-80 PC-3 / Sharp PC-125x

My PC-1251 woke up again, thank to your investigation and work. Great job!
I used your instructions except that I used a hot air metal plate at 100 degrees C for about 5 minutes to be able to separate the old display from it's frame.
Thank you a lot!

Works like advertised

For LCD replacement for Sharp EL-5100

I just finished repairing an EL-5100 and an EL-5100S. Both worked on the first try.

I soaked the metal frame in acetone for 3 hours and the old LCD came out easily. Left the adhesive in place, and used it to hold the new LCD.

I aligned the left edge of the LCD (the side without the bump) to the left edge of the frame (the side with the hole). Cleaned everything with isopropyl, blew off the dust, installed the zebra strips, crimped the frame in place and it worked!

Thanks for your dedication, making parts to repair a calculator I bought 45 years ago!

Works great to replace failing EL-5100S LCDs

For LCD replacement for Sharp EL-5100

I have two EL-5100S with slowly deteriorating silver LCDs. When I saw that new LCDs are available to fix them, I couldn't be more happy to try it out. Oh man! These new LCDs are perfect! Installation was not as difficult after viewing the videos. I made sure the zebra strips are perfectly clean and have no dust particles sticking. Worked for me on the first try. So, instead of acetone or heating, I soaked the old LCD frame for a day in alcohol. Once some part of the glue detaches in one of the corners with a little bit of pushing (being careful not to break the glass), I then pushed some thin plastic wedge between the frame and LCD to let the alcohol do its job. Easy to clean up. The glue didn't dissolve and holds the new LCD nicely in place. I also have a pristine and beautiful EL-5100 with the yellow LCD. That machine shows no deterioration yet (knock on wood).
