“Jose saved my daughters’ computer and me a lot of money. After she dropped it and the screen shattered we thought even the inside was damaged. Jose checked it out replaced the screen and gave me a very reasonable price. the best was that he completed the job in 3 days. i will definitely use him in the future and recommend him to family and friends.”–Joyce G., Davenport, FL

China, we’re told, can make anything. If you need some PCBs in a few weeks, there are a few factories in China that will do it. If you need a nuclear reactor, yep, there’s probably a factory in China that’ll do it because nuclear reactors are listed as one of the items facing new tariffs when imported into the United States. No, I am not kidding. What about LCDs? What about old-school character LCDs? Is it possible to find a factory in China that will make you the LCD you want? That’s what [Robert Baruch] will find out, because he’s repairing an old computer with new parts.

The object of this repair and restomod is a TRS-80 Pocket Computer (PC-1), otherwise known as the Sharp PC-1211. It looks like a calculator, but no, it’s a legitimate computer you can program in BASIC. [Robert] bought this computer for a bit more than $5 on eBay ‘for repair’, which means the zinc-air battery was dead, and unfortunately, the LCD was shot. The LCD technically works, but it just doesn’t look good. Sometime in the last thirty years, moisture got in between the layers of glass, polarizing film, and liquid crystal. This is not unique to [Robert]’s unit — a lot of these PC-1s have the same problem, many of these broken seals rendering the computers themselves useless.

This is an ancient computer, and replacements for this LCD are impossible to find, but because the Sharp PC-1211 is well documented, it is possible to find the datasheet for the original display. With that, it’s just a question of finding an LCD manufacturer that will do it. So far, the costs look good — $800 USD ($300 for tooling and 10 samples, $500 for another 200 LCDs) is what it’ll take to get a few units. [Robert] already has a few people interested in repairing their own Pocket Computers. You can follow the eevblog thread here, or check out the video below.

The replacement job will require disassembly, and one should carefully observe the steps in the video tutorials other users have created and posted on Internet. Or even better, leave it to a licensed repairer or somebody who has proven practical experience and knows how to avoid risk of electrical shock, ESD damage to the electronic components or the display panel - and can offer warranty for their work. Pay extra care with the cables connecting the mainboard to the display (LVDS, LED backlight and menu button board) as they can be easily damaged when removing the mainboard.

I am an IT guy who discovered repairing electronics by need - when looking to fix the hardware related problems I encountered with monitors, laptops, computers, networking, printing, audio-video and so.

I found that working with resources disposed for recycling is a very efficient way to learn, and solve many problems without big expenses. I agree that the cost of repair at specialized centres could bear a high cost - considering that fixing requires time, experience and somehow be lucrative. But younger generations tend to break technological barriers easier, and with the help of readily available information consumers can solve problems themselves when manufacturers can"t.

Due to its high cost, the logic board is the only part in the device that is not included in the liquid damage service. If the logic board has been irreversibly damaged, we will not be able to repair it and you will be refunded, minus the cost of return shipping if applicable.

It depends on the liquid. We reserve the right to decline liquid damage repair if the phone or device has been exposed to a liquid that may be hazardous in any way. Please call us at 1-877-320-2237 to inquire and make the proper arrangements.

Absolutely. Although salt water is corrosive and can be very damaging to electronic devices, we can still attempt to repair it. Our success rate on salt water damage is lower than that of a device that has been dropped in other liquid, but there is still a good chance that it can be repaired. If we cannot repair it, we will refund you the repair cost, minus the cost of return shipping if applicable.

First and foremost, do not attempt to turn the device on as that can cause a serious short circuit. Next, send the device in for our liquid damage service as soon as possible. The sooner we receive a liquid damaged device, the higher the chance we can repair it.

It is possible that a device can begin working normally on its own after liquid damage, but it is very uncommon. It is more likely that corrosion and residue deposits will begin to form on the logic board making the repair process more difficult. We recommend sending the device in as soon as possible, even if it is still wet. The sooner we receive a liquid damaged device, the higher the chance we can repairing it.

If we are unable to repair your liquid damaged device for any reason, your payments will be refunded, minus the cost of return shipping if applicable, and your device will be returned. If your device could not be repaired and you do not want the device back or do not wish to pay for return shipping, please let us know and we will recycle the device at our repair facility.

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 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.

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! :)

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!

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!

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.

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).

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.

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.

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.

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.

I repaired four Sharp PC-1211 successfully. Video tutorial of replacement is very useful and so replacement was very easy. Thank you very much Robert for reborn of these lovely PCs

Due to manufacturing issues, 100 % of the TRS-80 PC-1 pocket computers will need a new LCD display - most probably need one now. I am the original owner of one that is just getting to the point where without a new display it will become a doorstop. In what can only be described as a spectacular herculean effort this guy has created a drop-in replacement LCD for these collectible computers - thus literally saving them. The LCD fast and looks like a production part - this is not a kluge or prototype, this is the real freaking deal. It amazes the hell out of me that someone actually took on this project - thank you so much!!!

Perfect fit and function. Video tutorial on installation is a big plus. Out of all of the TRS-80 pocket computer series, the PC-1 is the one that is almost always plagued with a failed LCD. I own four of these pocket computers, all with varying degrees of failure, from light blemishes, to complete blacked out. The key is cleanliness, taking your time, follow the alignment procedures. If you are starting out with a "know good" operational unit, you should have success. Quick shipping, and quality packaging methods too.

I own several of these Pocket Computers (either Sharp PC-1211 or Tandy TRS-80 PC1), and I have been an absolute fan of these devices since I was a teenager.

I basically smoothed the defective LCD adhesive with hot water and liquid soap. Removing the defective LCD from its metallic case was a little bit harder than with acetone, but faster (I did not have to wait overnight for the acetone to activate).

I was right to buy several of these LCDs, I will now refurb my other devices, reviving them back to operating life, some 35 years after they were manufactured.

I have successfully fixed two PC1211s with these LCDs. After a couple of false starts (putting zebra strips in the wrong way round) I managed to get two machines working with the new displays. They do seem to better than the old ones with respect to contrast. The installation is a bit involved, but definitely possible. Thanks Robert, excellent work.

My PC-1 was retrieved from my to-be-recycled bin about 5 years ago **at the very last minute**, even though the LCD display was about 75% "roached out". Boy, am I glad I did. Being the first computer I ever owned, I just couldn"t part with it, even though it would probably never be functional again. What were the odds? Then I stumbled across these videos by some crazy guy who decided, "Hey, we can fix all these rotted LCD displays, NO PROBLEM!" after which he proceeded to create them and make them available to anyone who wanted one. Flabbergasted, I rushed to the store to buy some batteries to satisfy myself that the remaining 25% of my old LCD was "correctly" displaying characters, making an attempted replacement worth the effort. I then put in my order quickly (in case supplies should run out before I could respond!!) and a week later had the new part in my hands. My installation (having avoided all the cited pitfalls and possible missteps so well documented in the excellent video instructions) went smoothly. The computer works like brand new.

What"s so surprising is that this unit is to this day a functional and useful piece of gear which after almost 40 years is a testament to its overall ruggedness and efficient design. One could wax eloquent on the ability of designers from that time period to squeeze the most usefulness out of the parts available for the purpose. I cannot thank the _Half_Baked_Maker_ enough for creating this excellent replacement part. It has provided no small amount of joy to this PC-1 user.

It was really fun to be able to restore my old computer to better-than-factory condition by replacing the old dying LCD. The new display works perfectly, and Robert"s video on the installation process covered all the bases.
