Received fast, Works great

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

Good quality replacement LCD. Watched his instructional YouTube video and changed it myself, I would recommend.

Great replacement LCD! Works perfectly.

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

Good quality, easy to mount, working fine. Congratulations. I don't know why I have to write 100 characters in the review. This does not make sense.

Great product for almost forgotten calculators....

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

I replaced two displays of calculators in my sharp/Tandy/Casio collection of BASIC prgrammable pocket calculators.
Both work well now - without this display they were unusable . Thanks a lot!!!

One thing: The video is great, but the hint with the polarizer which must be taken out comes very late... I was ready with everything, when I recognized that the display is very dark. So I watched the video to the end. One additional iteration for me ...

Awesome

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

I got a PC-1 and 2 different 1211, and the three calculators have been fixed with this screen replacement. The video is very good, and it contains everything you need to replace it.

Perfect LCD replacement

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

A new life for a computer I have used while I was engineer student. I also repaired my CE-122 printer and cassette interface with new batteries.
Good information in video instructions and no problems with replacement.
Thanks for the product.

These displays are great and super affordable!!!

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

I found out about these displays from a gem of a Youtube channel called Robert Baruch.

https://www.youtube.com/channel/UCBcljXmuXPok9kT_VGA3adg

Robert has video's showing the replacement LCD displays he had recreated for the Tandy and Sharp pocket computers and explains/shows how to perform the replacement in a pocket computer.

After finding and reading his old EEVLOG thread for when he first came up with the idea to recreate these displays, I was amazed at his dedication and engineering Robert put into these fantastic displays. I was in awe to say the least. I quickly ordered 2 displays for my failing PC-1's - I received them very quickly - and after a Sunday afternoon and a little patience, I now have two working Tandy pocket computers. Without Roberts displays, my pocket computers would have been vintage junk destined for the bin. But Robert has given them new life. And the price? I paid 20$ each, which in my opinion, Robert is being extremely generous. I cannot convey enough thanks to Robert for these displays -- THANK YOU ROBERT!!

Revived an almost 40 years NOS PC-1251 :)

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

It was sheer luck that I got my hands on a NOS PC-1251 and that Robert managed to reproduce the LCD, for its original was long dead. The display came well packaged and quite fast from the USA to Germany and with the instructions from the video it was quite easy to do the job. I didn't use acetone but an other solvent (call Universal-Nitroverdünnung here) because what it is needed, is just something that dissolve the adhesive strips that hold the glass in the bezel. About 90 minutes later the old display could be removed and after a thorough cleaning I put everything together again.

Powered up, the display worked but I had strange effects with some pixels that never seemed to show. I asked Robert and followed his advice to remove the bezel and have a good look to the alignment of the contacts (hard to see as they are transparent and only show themselves under certain light conditions). I immediately saw that I was ~0.5 mm left of the gold contacts on the PCB and after correcting that, everything is fine :)

Thanks for a great product that allows us to keep these old machines running!

Awesome item and service

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

Outstanding project that gives a chance to bring to live the frist Pocket Computer in history and related items. Collectors community are quite gratefull. No yet tried to repair mine, but the item worths whatever the results are. A frist shipping was lost (may e COVID -19 issues) by USPS overseas, but kindly it was replaced inmediatelly at no cost.

Update: being in mind my poor skills, I was afraid of the outcome of the repair, but it was successful at the first go in both two machines: PC-1211 and PC-1210. So, If I did it for sure you can do it as well.

PC-1210 (the previous version and the very first Pocket Computer ever made) has only 3 G-13 batteries (instead of 4) a slightly different and simpler battery connections, but the rest is exactly the same. The TR80 PC-1 in the vid have some minor differences in respect PC-1211 (some connections plate under the speaker).

My two cents: Do not hurry up, work gently, take your time and go along process in two o three days in short enjoyable periods.
In my cases the screen alignment was not an issue. Just push the screen to the RHS. The centered contact alignment in the bezel window was not critical. The flexible worm contacts wiggle at first, but gently pressing them against the new screen edges magically got them straight (adhesion and compression made it, I guess).

In respect constrast: Previous to remove the pot dial try to adjust the dial. Even it is glued or painted, it is an aged non-iron made substance and it does not make much resistance to move with and tiny screwdriver form the other side of the board, at least in my PC-1210. Moving the dial full anti-clock wise made contrast OK. Nevertheless the PC-1211 (the first I restored) I went directly to remove the entire dial as mentioned on the vid (Error: may be I should have tried first to move the dial) but the screen still is too dark, with noticiable shadows. I measure a resistance of 800 K of the pot rod. With half charged batteries it improves visibility (constrast is reduced). I think I can live with it, otherwise I will solder a resistance and see.

Again, thanks to Robert for this impressive project.

I guess that other SHARP machines could be us this screen (PC-1500 , 1350 series ? and may be others). It will be nice to have a listing of them.

Very fine LCD display replacement for Sharp calculators

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

Very fine replacement: a modern exact replica of the LCD display for Sharp calculators 1200 series. Very clear, more durable, good video with substitution infos, need a minimum of practice and patience.
Work 100% like original, but follow exactly all steps indicated into the video to substitute it.
I hope will be made more LCD for other Sharp calculators soon!
Seller is a very kindly person, no problems to buy, very quick to ship, cheap shipping cost.
Many thanks again, my Sharp live again!

Giacinto | Dec. 1, 2020

Excellent!

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

The screen was a very good replacement and the videos clearly explain its use. The only issue is with contrast setting: my unit was supposed to go on 6 V batteries (the original manual says so) since mercury batteries were uncommon in Italy at the time, this means that the new display is a bit too dark even with the trim disabled, it probably would work perfectly on 5,4 V, I will solve this issue adding a small resistor.
Anyway the replacement display is fantastic!

Amazing

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

Got my Sharp PC-1251 working again! I'm just amazed about what some people do to preserve vintage computer technology. This screen is a direct replacement, and works perfectly.

Mitsunori | Nov. 22, 2020

EXCELLENT!!

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

The Youtube video was very easy to understand and helpful. I don't understand English, so I couldn't understand what the "contrast adjustment" part was doing. For the time being, I used 3 LR44 batteries and a jumper wire. We would like to pay tribute to The Half-Baked Maker's activities. I'm really thankful to you.

Excellent LCD!

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

I purchased the LCD of PC-1211 and PC-125x and was able to revive PC-1211 and PC-1255.
Thank you very much.

I'm sorry, I made a mistake. (I wrote PC-125x in the review of PC-1211.)

Hidefumi | Nov. 16, 2020

Excellent LCD

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

It was saved that my PC-1255 was revived.
If an LCD for PC-1245 or PC-126x is also made, I definitely want to buy it.

Tomohiro | Nov. 4, 2020

It was a good part

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

I wanted to use the PC-1251 I used in the past again.
Only those with a damaged LCD were available.
I couldn't repair it until now, but I was able to repair it with this part.
I was very happy with the existence of this part.

Resurrected my pc1251 I bought in 1986

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

The YouTube video is clear and the replacement of the LCD relatively easy. You just need to be careful and meticulous.
I am really happy this LCD has been made available.
Thanks a lot for your time and hard work!

Great product - restored my Sharp PC-1255 in 2 hours

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

Thanks a lot for instruction video on YouTube and this kit! Restored my Sharp PC-1255 in 2 hours with these great instructions. Acetone worked much faster for me (~ 80 minutes). Instead of Q-Tips and Iso, a good supply of simple Walmart pre-moistened lens wipes does the job as well.

Saved 3 Sharp PC-1211s from the bin

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

I recently won a few Sharp PC-1211s in an auction. Sadly the LCDs had all succumbed to screen rot, which was all the more tragic seeing as everything else in the units worked perfectly. I put them away in the hope of using them for parts when a unit with a working LCD showed up.
While browsing through Pocket Computer content on YouTube, I happened across Robert's tutorial on replacing the LCDs in TRS-80 PC-1s, and through that, his Tindie page.
Ordering was straight forward and easy, costs including shipping were transparent.
Shipping was quite fast, and the biggest delay was in customs on my side of the pond. The quality of the modules is fantastic and installation was very easy thanks to the Youtube video.

Robert's modules will save quite a few of these pocket computers from an unnecessary death.

Thank you!

Kevin | Sept. 30, 2020

Excellent Product! My TRS-80 PC-1 is like new!

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

Process was straight forward just like in the instructional youtube video. Thank you for taking the time to produce this display.

Great!!!

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

Thank you for shipping as soon as possible. I'm really thankful to you. I replaced the LCD that I received. It worked fine. I couldn't help but watch the liquid crystal darken little by little every year. However, it has healed after 35 years. I didn't expect this day to come. And the memories of my childhood have been revived. Your job is a historic achievement. I'm really thankful to you. Pay tribute to your work.

really wonderful!

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

Hello.
My nostalgic PC-1251 has revived !
Because I bought seven LCDs,
I got a PC-125* with broken LCD at a low price, at auctions, etc., repair it, and enjoyed so much.
There are many repaired PC-125* in my toy box!lol.
Your tutorial video that was easy to understand, so it was very helpful.
The Knack is to stick the liquid crystal rubber as original （to the top, bottom, left, and right without making any mistakes ).
Thank you for making a perfect LCD.
That's really great!
Again Thank you !!

I have been waiting for this product to be produced for years and was not disappointed. I have fixed 3 pocket computers with these new screens.

Thanks for making this product.

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

I bought a replacement LCD for Sharp PC-125x. I was able to exchange according to the tutorial video. Since I didn't have acetone, I peeled off the bezel using stationery sticker spray for two days.
In the original state, the liquid crystal turned black, and the state of the machine could be checked only with the BEEP command, but it was completely restored. Thanks for making this product.

I feel so happy!!

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

I had ever owned a pocket computer sharp PC-1251 when I was university student. It was a up-to-date computer and enjoyed scientific programming whenever I want to. So, I lived with it everyday, everywhere, and I felt happy when I use it. Unfortunately, its lcd came to black, and felt sad. For over 10 years I put it into a drawer, and I fortunately found this lcd part. I got it and the day I received, I replaced it. It came to success and display letters again. I felt happy and I remember my youth over 30 years ago. Of course it seldom came to useful now, it is almost my time machine. I appreciate the seller for selling such a wonderful part for old computer. The pc came back to be my treasure again. Thank you so much.

Excellent replacement LCD

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

Successfully repaired two PC3 and one PC1250.
Placement and orientation of the flexible contacts strips is critical.
Keep track of how they were originally located and positioned.
Left end - right end, upper strip - lower strip , PCB side - glass side.
The side that faces the PCB has indentations in the strip from years of contact with the PCB.
That side will not work well if placed against the LCD glass.
The strips should not overhang the edge of the LCD and make contact with the metal bezel.
I had to reposition the LCD and strips three times on one of my units.
Risking metal fatigue and possible tab failure of the bezel.
The LCD needed to be all the way to the side of the bezel with the hole.

Thanks you Robert for this fine product. Well done!!

Really great job. Thank you very much.

P.S. to correct the contrast I’ve just lifted middle contact of the variable resistor - it works perfectly in my case :-)

Excellent product and delivery

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

Arrived well packaged, exactly as described. Followed the youtube installation guide and my Sharp PC-1211 display is new again. I truly thought it was dead forever. The only deviation in the instructions taken was to allow the old display to soak in acetone for only about 4 hours. I they carefully tested releasing the display. The old adhesive strips released the old display, but remained completely on the bezel and stayed gummy, This allowed me to carefully position the new display and stick it into position without a shim or having it shift around. Perfect installation on the first go. Thanks so much for taking the time to reverse-engineer and provide these displays. I could not be happier.
