Great video. When someone makes look that something complicated is soooo easy to do; it is because that person is a Master in what he does. Cheers!

Really enjoyed this LCD repair watch video! It's a little complex but certainly doable with the right tools.

Congratulations on your channel, I follow with great interest and I want to thank you, I have found many help and many guides to repair some watches of my modest collection! Thanks 👍👍👍

This is incredible!!!! Thanks for sharing your knowledge, I hope you’ll share more and more tips about how to fix things especially the vintage one ☝️

If going the polorizing filter route, I would make up shims from the left over material, drill appropriate size holes and install them under the lcd clamps. That way you can tighten the screws properly and would not have to worry about the lcd moving around. Good video.

Thanks for helping me finally understand how my Casio Pathfinder display could malfunction (it it is mostly faded until stored in the dresser away from light). Also, the compass readings now only say north or east (regardless of direction). It was a swell watch for about a year (maybe less). Excellent video.

Imagine teaching yourself this before the internet. Many dead watches later. . . . . . . .This is outstanding stuff! Thanks!

Terrific video. As always very helpful and informative!

I've removed the old polariser and replaced it with a new one but there are some modules where letters and symbols are printed on the polariser itself. Pasting the new one over the old makes a lot of sense!

Outstanding, what a transformation. I will share this video on Seiko Passion FB group as this might help a few guys in there.

i like the way you act in fixing you are professional man

..super your notes regarding fading repair .. congratulations and grateful for your videos ..

Very impressive. Very good video.

My parents bought me this Seiko watch back in 1983. I wore this watch for 20 years , until moisture was getting in and would show up in the display. The O-ring on the battery cover had dried out and I used electrical tape to cover the battery cover. But in the summer time when you would sweat the electrical tape would move and the moisture would get in. One day it just died and I threw out the watch. To bad your videos weren’t around then , I would of mailed it out to you to see if you could fix it. By the way love all your videos , keep them coming.

With apologies for digging these comments up after 5 years, I have a question about a faded LCD/Casio T-2000 project I'm plotting… If you measure an existing Up Converter capacitor which has already degraded, won't the replacement with a capacitor of an equivalent value also provide insufficient power? Really you need to know what spec that component had at the factory. Also, so many thanks for these videos. It’s a great (and also scarce) resource.

new sub indeed! lve those watches since I was a kid 40 yrs back :)

You sir are a master at what you do. Subscribed.

Great video are you self taught,another great watch and informative video 40 years ago I remember looking at that watch in a shop window,it's on my list.

Generally nothing happens to ceramic MLCCs with time. Sometimes they crack across and then they fail, either losing the bulk of their capacitance or going short, but there is no gradual expected decline in capacitance, no chemical changes, these are extremely inert materials, so they shouldn't be replaced unless indicated by measurement. It's a good idea to measure in-circuit so you don't have to needlessly damage the substrate by soldering if you have a good idea of the circuit overall in cases where there isn't a lot of parallel capacitance, and if it measures too low or you get a resistance measurement across is too low, then replace. Boost circuit capacitors are not critical in capacitance, 10-20% is fine. They have variation from the factory. Thing is you never know whether your new MLCC will be a quality manufactured product that is going to last (especially if you haven''t bought it off Murata, TDK or Kemet), or whether it has a hidden fracture or material inconsistency from the factory that can cause it to crack; and the process of desoldering and resoldering MLCC can fracture them via thermal shock, so desoldered MLCC should normally not be reused even if they measure OK. So if your in-circuit measurement gives you a good indication that they're fine, leaving them alone is an adequate course of action.

From my experience, it has always with the polarized film. Especially watches above 6 or 7 years from production date. It seems that watches that kept in a long time in the drawer or dark places may subject to the fading LCD. If it was less than 5 years or less the condenser might contribute to the failure. This is a good video anyway!

That is one incredible job right there. Cheers.

2 years ago i saw your tutorials and now I have a little colection. Now in Europe in very dificult find digital watches in an afordable price

Very mind boggling and great talented JOB.

Cleaning the zebra strips and display contacts with some alcohol can also help with a faded display. I did this with an old LCD game and the difference was night and day. I just received a watch that has a very faded display (more clear when looking at an extreme angle). It also fades out when pressing a button (not when pressing the light). Also the digits change slowly. I think this is probably a bad capacitor, or a dirty contact somewhere.

Fabulous video, very helpful.

Great job! I like it, Thanks you I can try repair my 3 vintage watches from my collection. Many Thanks!

In my case I can't find a local distributor of polarizer replacements. So I use polarizer films from old LCD panels. Some of them are thick and touch enough to peel without damage and can be recycled. I use solvents like lacquer thinner when peeling off the film using Xacto knife and wiping off the glue.

Great job 👏 loved the video

I dont understand the thinking around the capacitor. You measure the existing capacitor to know what you should replace it with. But if the capacitor is faulty and you exchange it for a new one with the same value as the faulty one you would get the same result right? Why are you expecting an improvement if you change one capacitor with another with the exact same value?

brilliant buddy cheers for sharing

Excellent video.

Very comprehensive video! I’m wondering if you have anything about LCD screen Seiko 0644? Digits on the screen are faded pretty badly plus the fact that the battery last 2 days only. Any advice? Or video how to disassemble? Thanks in advance!

Great! I usually remove the old one, a tricky job but works nice... I had done one few days ago, it was a Casio W-350,module 152 with a reddish front polarizer film.

Simply amazing, thank you.

hello sir, thank you for sharing this methods. keep it coming. cheers. :)

Thank you for these very helpful videos. Do you happen to have any recommendations for watch repair in California? Preferably someone with your attention to detail?

Very interesting video. It made me inspect my old Casio W-780 with the 549 module again. It has a very strange contrast problem, I've never seen before. Instead of an evenly weak contrast over the whole display like in your video, it shows a "dynamic" loss of contrast depending on what is shown on the display. That means, the same segment can have full contrast at one time and weak contrast at another, depending on what the other segments show. Or a segment that is supposed to be off, is sometimes visible with a weak contrast. So this can obviously not be cured by simply sticking a new polarizer on top of the display. So after watching this video, I started to think about whether this phenomenon could also be caused by a weak capacitor. Unfortunately I can't find any technical document about the Casio module, nor any information about such behavior of an LC display anywhere else. The module has three capacitors in a row, so I don't even know which is the up converter (if any). What do you think, may this problem be related to a weak capacitor? The display also shows a very slight amount of the rainbow effect, but it's barely visible.

tenho um Casio G-shock DW5600 máquina 901 e troquei a película polarizadora e ficou bom. usei a película polarizadora de uma calculadora. ficou muito bom!

If you read the capacity of a damaged condenser you have a wrong reading. When you replaced the capacitor with one of the same capacity you have no changes. The question is, what was the original value of the capacity before the damage!

Great video. 3 Casio CQ-82 multi alarm clocks have just come into my possession & they all have the same faded displays. Can the same kind of film help fix the problem?

Thanks for your videos! I'm doing an AC reset on a vintage Casio Skywalker. The 12:00 comes up during the reset, but if i stop the reset the module goes blank again. If i hold in a button while doing the AC reset the watch works but a bit more faded. If i let the button go it goes blank again. I wonder if you have any suggestions?

I enjoyed your video. Thanks for posting. The problem I see is that you measured the capacitance and then replaced with exactly the same. Your result was just what I expected. If it was the capacitor, then the value you measured was the value after it drifted, not the value it was when it came out of the factory. I appreciate you do mention that you can't find the original specs, but replacing like for like will result in no change.

amazing video!

hello sir, is there any differences between removing the old polarizer instead of new polarizer stick on the old polarizer? why in this case it is not becoming negative display when you've tested it?

hello and congratulations for the explanation. I wanted to ask where you can buy or download the manual you used in this viedo. thank you so much

Very amazing video again. In my opinion it would be better to cut the polarizing film before some smaller to prevent what you described, that the film is liftet by the guides. Because the visible part of the display trough the window is smaller than the LCD itself. I think it can be 1mm away from the border without beeing visible later. And the thickness of the display would be the same as before in the areas of mounting the brackets. On the other hand not so easy to install. What do you think?

Hi there, What a great fix. I have a Timex Expedition that the chime and alarm are faint. How do I get this to sound louder? the pieso sounding plate is fine and the battery is good and strong as it was replaced but still the problem persists, Can you help in what to look out for?

Hi, very helpful video, thanks for it. I´m a watches entusiast, specially mechanical ones, but I like the old school lcd ones too. Few months ago I purchased an old scrappy "citizen cryston lc", as far as I know a really old model. I put a new battery on it but barely turned on. I cleaned all circuits with isopropyl alcohol and after that it turns on, but after 1 or 2 seconds the screen dies slowly, then turns on again only for die again. Do you think the problem is one of that 2 you talk in the video? there´s almost any information about those watches

I have a vintage lcd digital watch which display is pretty dim. Thanks to you I know that it probably needs a needs a new polarizer. But I’m a noob and don’t want to mess up the watch, also I would like to add a led backlight to better see the time in the dark. Furthermore it needs a better sealant on its back cover plate for more sweat resistance. Would you be able to help me out?

Nice video. Are you think the polarized film from cellphone or tablet, could bem also used?

good work..btw any idea how to get rid of the uv flare on the glass due to degradation of uv over the years

Good job👍

Hi friend, a doubt, where did you buy the capacitors bands?

"Attaching the film to the display is much more riskier".... he hasn't seen me use a solder iron. For him it's much more riskier.... for me putting that film on, I could do in my sleep. Thanks for the video

I wonder if you could have removed the old polarizing film first? When I have modified negative LCD's to positive (I hate the dark LCD's), I have always taken the old film off first. Thanks for the video. I've got an older 1545 module Casio DW-5600E with a faded display. I'm going to try to invest some time in taking the old polarizing film off and installing new film.

Your video verry much usefull to me.

super cool, thanks!

Great job.

Hi, my old Orient music alarm watch has also faded digits and in addition there is like a rainbow shade that makes the vision even more difficult. I guess it is due to the aging of the original polarizing sheet inside. I´d like to ask the community if someone has removed the original sheet before placing a new one and if this job is easy. I see a high risk of broeaking the LCD in doing so, so i´m not convinced it´s worth enough. Any tip is welcomed

Hi ,, I’ve been looking for these filters and can’t find them on eBay. What I can find is big sheets self adhesive but for galaxy phones . They are very cheap but was wondering if they would work? Is a polarising filer just a polarising filter or are there many types . ?

Very helpful thanks

Good video !!

When LCD watches first came out, the displays only had a life expectancy of around ten years, before the chemicals inside degraded... and unfortunately, that is still the case today - even with large back-lit TV screens.

What is the book you're referring to that talks about the upconverter? That looks like an amazing resource to have.

Dear Vintage Digital Watches, I have a Seiko A359 digital LCD watch that has two problems: 1. It is losing time; and 2. The digits while still showing good contract are a bit fainter than previously and sometimes the display goes out completely when the ambient temperature is cool. Is there any possibility that I could send you this watch for an overhaul and repair?

Good job bro

I think that if the original capacitor is bad, the reading in the multimeter is giving the bad capacitor value, so changing it for a new cap with the bad capacitance is useless. You would need to know the original capacitor specifications.

Getting a venerable Seiko 0439 back to life thanks to your video! Where did you get the polarized adhesive film? Thanks so much for sharing!!! Long live to Vintage LCD! (Thanks to you)

cool vid!

Hi, do you know what could cause the LCD digits to change a little slowly? Thanks

Hi, do you know how to determine if the lcd watch is broken or not? the lcd from my old watch is not showing any sign but I check from the lcd contact in the board there is voltage about 1-2V.

Hi Tibi i think i was send you a message here but m not sure so here we go again. I found many polarized films but almst all are for cell fones so is the same ? Also one of them says active i imagin the active 3D lens . Anyway please let me know the one for watches i have many with bleeding screen and also faded digits. How do you put in to lcd i mean do you use glue ? Thank you

I've got same watch with same problem. Unfortunately I'm not able to fix them like you.

sir what power lens microscop are you using

Hello, I came across your page while searching for some information on a Seiko Final Fantasy watch I bought back in 2001. I never worn it and it pretty much sat in the box on the shelf along with a few others in my collection. During the Covid-19 visit, I found myself a bit bored and decided to replace the batteries in old watches. All worked out well except for the Seiko Final Fantasy watch model. Now, this watch is somewhat sought after but I prefer to keep mine. After replacing the battery, the numbers are dim and fairly broken in places. I don't know if you've seen the watch or perhaps know of it. If you do, I was wondering if you might have a fix for it? Seiko offices are closed because of the virus, as if most watch shops around me. Could this also be an example of a capacitor problem or a LCD replacement screen? Your thoughts please.

Do you have any video on LED Vintage watches

Hi my friend where do you buy the capacitor?

Excellent..

excellent

Thank you for your videos, they are very educational Where can I find a book like the one you show in the video to learn theory? Thank you.

Hi! very good repair reports. I have a question for you about the repair of Casio's watch??? There is the next the situation: clock Casio DB 31 and CA 50 in them one and the same the reason. when the battery is inserted the watch run if you can get the battery and insert back the clock is not included , you can several times to set and get the battery out and that does not happen. the clock will lie down 5 - 10 minutes without battery, then insert the battery the clock starts to go again. It happens that inserting the battery indication on the LCD is not complete and seconds do not go. it is necessary to remove the battery and reinsert and then maybe the watch will work normally or do not show. Is that some kind of capacitor? if Yes, what and how to define it???

Nice video! Wll explained. However, I have a different issue that bothers me. What could be wrong with digital watch when it doesn't react on commands (pushers)?

Very good

such a good video.

Nice video. But where do you buy the lcd watch repair book? And the capacitors where do they buy ?. If there are spots on the display, can it be repaired? Thanks Fabrizio.

Hi, from Brazi! Is there any way to fix when some of the digits are missing?

Bonjour et bravo pour vos vidéos très intéressantes j’ai une montre citizen mouvement lcd 9460A les condensateurs ne sont pas soudés sur la carte mère et sont manquants avez vous les caractéristiques des condensateurs et leurs valeurs pour le remplacement merci par avance Gilles

I would imagine that before attempting either of these two fixes, you'd stick a new battery in, right? Then, if that doesn't change anything, proceed to the capacitors...

Thank you verrrrrrrrrrrrrrrry much bro🤩🤩🤩😎

Muy buenas tardes. Q excelente. Las reparaciones. De los dos relog es. Vintachs.

If I want to invert the light on the LCD screen of my car's head unit with a polarizer so that instead of black letters on a lit up background, it has lit up letters on a black background, is there a specific kind of polarizer I need to look for on ebay?

Great video.. one question, the polarized film can be use for negative display mod?

Is this the same kind of polarizer as those used for cellphone lcd´s?

hello I have a casio m-15 melody and the screen has the numbers engraved even if it is without a battery how can you repair those screen or clean greetings

Hello congratulations for your great collections and thank you for the videos . i have some seikos lcd with differents failures im wondering if you can help me to restore them . Fist i have an exactly model the world time but is has strange behavior when i press the buttoms the display fails is quite difficult to set up . Also the battery dont last to much . What is the isopropanolI and where i can fund it . Isee the batch of capacitors so i wondering how you extract from the strip . Sorry may sound a stupid question but i just start on the watch repair and never see how came the capacitors . Sorry for the long message and also for my english im not english speaker .

I am not sure someone has asked this yet (looking at the comment)... and in the video I could hear that you answered it so... for this watch, if it is not the capacitor... do you know why the displayed has faded at the first place ?... what are the causes of this? Do you know? Also does the polarised film make the display darker than before or not ? Thank you ! Great video

Hello, do you know where can I buy the module of watch casio? all circuito to make a new case to use it?

Impressive May be stupid question: would it be possible to stick the film below the watch case glass instead of sticking it on the display itself? Do you have to pel the old polarizing filter off before sticking the new one? Thx

That was amazing... but what if the numbers displayed in the lcd is not complete ?

What is that watch repair manual?
