Thanks to Robert C Baruch

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

Hello Robert,
I have two Sharp PC-1211 which weren't useable anymore since years due to the wellknown LCD problem. I'm a sailor and a fan of astronomical navigation. The mathematics for that isn't the easiest one, that's why I tried in the early 80's to write a helping program in BASIC. ( 1 step, 0 memories left !!)
I succeeded in that and were using the program on that Sharp PC-1211 together with a sextant on many sailing trips worldwide.
I'm not so experienced in other modern program languages, that's why a friend of mine currently tries to get run my old BASIC- program on a windows based computer.
When I heard about your activities around the replacement of the LCD I was really curious, because that was maybe MY SOLUTION. I ordered two new LCDs and with the help of your perfect video on YouTube how to arrange the replacement, I succeeded !
Now, again I have two perfect working BASIC - computers in my hand.
Thanks a lot for your excellent help in that matter.
Best greetings to you from Germany
HANS-ULRICH

Awesome products and easy to install

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

It’s a pity to see our beloved pocket computers dying. Thank to Robert, this is an old story.

I am the worst handyman I know but, thanks to the videos, I have been able to replace so far 1 PC 3, 1 Sharp PC 1251 and 1 Sharp PC 1211. So, if I can do it, everyone can.

Thank you Robert.

PS: I changed today (Feb 18th 23) the screen of a PC 1245.

Worked like a champ on both my PC-1 and PC-3!

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

Thank you Robert for taking the time and engineering these displays so our fellow Tandy handheld PC lovers can bring their PC-1's and PC-3's back to life!

I've done both and now I have two fully operational units along with my PC-6. Your engineering was spot on and instructions easy to follow. My only gotcha was the small ribbon cable on my PC-1. After the display was replaced it would go blank if the the two boards were folded back together, yet come back to life if they spread apart. Turns out the small ribbon cable connection near the row of short connects that tied the two boards together had a short section that was making contact when the boards were closed. Once I spotted that and folded the extra section over it worked like a champ.

Now I need to find a way to fix one of the hinges on my PC-6....

Well done!

Chuck

Great

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

I was looking for a long time for this LCD to bring back to life this computer to which I am very attached.
It's the first computer i bought, in 1982, and on which i learned the basics of programming.
I've replaced the LCD following your instructions and everything went all right, it works really really fine.
I put a piece of plastic under the slider of the potentiometer instead of removing it, it is easier and it works very well.
The shipment was very fast with no problems.
I would like to thank you for this excellent work.

Nice LCD

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

Another saved RS pocket computer. Installation takes a little care but is not too difficult. This LCD was a happy find.

An excellent replacement display for my Sharp PC-1211

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

The display looks beautiful in my PC-1211, I would highly recommend it to anybody needing a replacement.

Not only that but the video detailing the process is excellent and very easy to follow.

Top marks for managing to recreate the display for this little machine at such a reasonable price, it has brought back my brothers machine from the dead, he's had it from new so it is a nice piece of family history too.

It is a shame that the UK VAT rules are so ridiculous as it took 5 weeks for mine to arrive via a forwarder and it about doubled the price, so something to be aware of if you're in the UK and need just a single display.

Another one lives!

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

When I decided to get into vintage pocket computers, I bought a Tandy PC-3, not realizing that the display was completely gone (pictures rarely tell the full story). Undeterred, I ended up getting a Sharp PC-1250A in perfect working order, but of course I held on to the Tandy. I knew Half-Baked Maker had reverse engineered the display for the Sharp PC-1211, but I didn't realize until a few weeks ago that he had also reverse engineered the display for the Sharp PC-1250 series! Naturally, I pounced. I went ahead and got 2 just to have a backup for my 1250A, but I was really excited to try and get the Tandy working again. I've got to say that I was a bit nervous using acetone for the first time ever, but everything went very well and very smoothly. Definitely watch his video a few times before attempting this repair; it's amazingly clear, and he goes through the entire process slowly and methodically enough for any beginner to easily follow. If you have a PC-1250 or any of its brethren with a bad display, don't hesitate to order a replacement! You'll be very pleased with the results!

Very great replacement!

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

My PC-1211 had already shadows and it's only a matter of time before it takes over the whole display. So after I saw the videos I bought 2 displays (this and one for my 1251). The instructions in the video are very clear. It took about an hour and a coffee to change the display. Now my PC-1211 is fully restored and I don't have to be afraid, the display will be defective in the future. Thank you so much! :)

Really great!

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

I was giftet a PC-1251 with a complete black LCD. Coincidentally I stumbled over the YT channel of Robert. After I saw the videos, I didn't hesitate a long time and bought 2 displays (this and one for my PC-1211). With the video it was very easy to change the LCD and the PC-1251 is back to life again! I'm happy that people can now prevent the great PCs from ending up in the garbage just because of a defective display. Thank you so much for this! :)

Got my TRS-80 PC-3 display working again

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

Fast Shipping. I was able to repair my TRS-80 PC-3 without any major problems. This is a pocket computer that I had originally purchased in the early 1980's. Followed the tutorial by Robert Baruch on Youtube to make the repair. I was successful even though I first tried to put the display in upside down! I guess that I needed someone to keep yelling white side up during the operation. We did need to purchase a fresh bottle of acetone to replace an older one that my wife had. The old one did not work at all.

Easy way to restore these pieces of history

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

Thanks Robert for taking the time and ingenuity to make this replacement LCDs, with your video and a little common sense it is really easy to fix these wonderful computers, I finally restored a Sharp PC-1211 that means a lot to me as I started my career in computing sciences when I was 10 experimenting with this 4 bit computer/calculator. Kudos!

Perfect LCD, thank you!

I just replaced the lcd on my sharp pc-1211 and it looks great. Now the restoration is complete. I had just previously restored the CE-122 printer and cassette interface and now have complete working setup. Thank you!

Received fast, Works great!

Thank you for this replacement LCD. What used to be a useless pocket computer, SHARP PC-1251 with a broken LCD, is now usable again.

Works great!

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

This allowed me to restore a PC-1250A I bought on eBay. Its screen was all black. No problems at all with the replacement- I did watch your Youtube video instructions. Now I need to find a replacement belt for the tape player in the associated CE-125..

I'm amazed that there was a reasonable cost way of duplicating these LCD displays. I definitely need to design a custom LCD display for my next project.

Raffaele | Sept. 4, 2021

Worked immedietely

Brilliant project and end result that breaths life into old

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

I don’t know where to begin to say thank you for this brill replacement LCD. Fitting was straight forward and the results startling. What had been a useless pocket computer, PC-1251, is now usable again. I didn’t need to do anything with the contrast wheel except to turn it up quite high and put two new batteries in. I have a slight issue in that digits 3 and 4 in from the right are flaky, missing pixels or too many pixels. I’ve tried refitting 5 times now, and won’t do it again as I could feel the LCD bracket lugs starting to give way. Even with this you can always make out what the display is.

All I can say is wow! I wouldn’t even have got off the starting blocks with this project, much, much less had the skills to get it to production.

Great product, support his efforts - Buy with confidence

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

Another great product. I've purchased 5 or 6 of the LCD's for the PC1 and all worked perfectly. I recently got a couple PC3's of which one of them had a dead LCD. I did a blind BEEP test to confirm the unit functioned and purchased. I'd say the PC3 is a little easier to work on and replace than the PC1. Great video support as well for instructions. I'm going to buy a spare LCD for the other PC3 that will likely fail over time, as well as a spare or two for the PC1. Thanks Robert and I look forward to other projects you may have in the works. And a special thanks for supporting these old units and keeping vintage computing alive and well. . .

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!

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.

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!
