Not to revive a dead topic, but if you still have that digitizer board I just did a bunch of work on DTK Digitizers and could help diagnose the issue, or I'd be happy to buy the spare board as a back up part. I do a lot of cintiq repair.


I finally obtained the internals of another Cintiq so I removed the not working screen and replaced it with the working one keeping the case and the manual controls boards (power button, expresskeys and image control). The new screen came with the three back boards included so I have them for spares now.

The old screen had four or five stress marks in the LCD after the accident that appeared as faint dark spots of the size of a fingerprint so I guess it is of no use for you. Also, it is heavy and would risen postage costs a lot. So I could send you the working CCFL Driver board, the working Display Controller Board and the defective Cintiq mainboard.

 Apart from that it is all screws, white plastic covers of the boards, cables connecting the boards, the metal frame shielding the LCD, the digitizer sheet behind the LCD, the CCFL tubes and all the light diffusion layers between the LCD and the digitizer sheet. Oh, and also the LCD motherboard that is composed of two pieces but I can't remember now if it is soldered to the LCD flat ribbon cables or uses connectors.

If you want anything of this, please send me a message. I live in Canary Islands, Spain, so I have to post from here.

Do you mean Surface Pro 3? Just go with your Galaxy Book stylus to a shop where the SP3 is in exhibition and try it on the SP3. If it works, then the drivers should work, but I don't believe there is any Wacom Control panel for those devices.

Wacom made some time ago some screens 15" and 18" or so that look similar to the Cintiqs but without ExpressKeys and they work with the Blue stylus I showed you in my photo, so the sensor is compatible (100% sure they would work also with the stylus from my Note 4 phone), but I don't know if the drivers for these screens will work in Windows 10 since they are quite old.

The small tablets used in some bank branches, Post offices and the like for signatures are also Wacom devices and I have tried them with my Note 4 stylus with success (and surprise from the bank employee  Grin)

Well, the Wacom device in the Samsung tablet is not an Intuos or a Cintiq so it will not work with those drivers and will not recognize a Wacom Pro pen or any Intuos 4/5/pro stylus. I don't know exactly about the Wacom device in the Galaxy Book but it is probably of the same kind used in the Galaxy Note series of smartphones and tablets. One easy way to check this is to try the S-Pen from a Galaxy Note phone (any, at least from Note 1 to Note 5 will do) in your Galaxy Book. Or try the Stylus of your Galaxy Book in a Galaxy Note Phone (you have to remove the phone's stylus for the phone to start scanning for a stylus.

If they work, then your Wacom device is what is known as Wacom TabletPC sensor.

In that case, of all the styluses you see in this picture, only the two at the right will work in the Galaxy Book. The rightmost is the stylus of my Galaxy Note 4 ant the other one is a Wacom stylus from an old tablet but I can't remember the name or model number:


Unfortunately you won't find the needed drivers at Those sensors are made for computer manufacturers to include in their products and Wacom position about it is that it is the manufacturer who have to provide the drivers.

My bet would be to try to use the drivers from some laptop or Windows tablet that uses the Wacom TabletPC sensor. If your Galaxy Book stylus works on it or the stylus from that laptop works in your Galaxy Book, then chances are the driver will be compatible. That doesn't mean the task of making this driver to run in your tablet will be straightforward but at least you will know you are dealing with the correct one.

Hi CableMender,

Any updates since May? did you get the thing to work? I recently repaired an identical one so maybe I could be of any help if you are still stuck with this.
5  Screen Tablet malarky / Heyaaaalpppp / Re: Laptop screen to wacom cintiqfor drawing on: October 26, 2017, 01:58:11 PM
the active area (at least on my intuos 3) is the area that is dark gray on your image. idk what the white marks are for but they are not the hard marks where the active area ends but on the intuos pen end touch my brother got, the active area is a bit bigger than the marks but doesn't extend all the way to the edge of the tablet.
I can't really say anything about the intuos 5 but I'd guess that the active area (aka the area where the pen works) is a bit bigger than the markings but not the whole dark gray area and definitely not the (light-gray) case.

In the Intuos 5 and pro, the White marks (they are really LED lights) define the active area. The pen will not work beyond this area. The Dark grey area is bigger than the active area because this way your pen will not bump when you reach the border of the active area. This was some of a problem in Intuos 4 and older. It is an unpleasant sensation and erodes the nib faster if you frequently reach the borders and bump between the drawing surface and the case.

When placing an LCD screen over the tablet, the pen will still be limited to the active area. It will not extend magically beyond that, of course. There is a calculator somewhere in the forum that allows to compare Intuos models and typical LCD screen sizes and see graphically which one will fit which each other.

I see your mention of the Intuos 4 was an errata, but anyway, just in case this information is useful to anybody else, Here they are the Intuos4 and the ExpressKey Remote in perfect harmony.

My guess is the remote would also work with the Bamboo since they use different drivers (not different versions of the same driver)

It is a pity Wacom removed support for Intuos tablets below Intuos4 from their newest versions of the drivers. A pity and a nonsense, because the Intuos 2 and 3 still work perfectly well in Windows 10 but since those drivers are not being developed anymore, the compatibility of Windows with those tablets will end soon, I'm afraid. (and also the  Cintiq 21UX DTZ and Cintiq 12)

Only option I see is a bootleg driver or hacking the original old driver to fool Windows into thinking it is a different service.

Unless you get it etched in the areas you need to paint, or have a specific paint, the tendency to peel off is to be expected. 

Yes, but the original glass had the border painted in black and it doesn't peels off at all. As I said, you need to scratch hard with an exacto knife or similar to remove it and even so, it is not easy to remove.
8  Screen Tablet malarky / Heyaaaalpppp / Re: dropped 21UX 2nd gen not responding to stylus. on: October 24, 2017, 03:40:45 AM
I have the glass to replace the one I broke. It is 2mm matt glass. So to hide the metal edges of the LCD and double-sided tape, I tried to paint the black border as in the original glass, but things did not work as I thought. I spray painted it on the inside but the paint does not stick well to the glass and it "peels". Obviously, if I stick this to the double-sided tape, what will stick is not the glass but the paint that will come off and the glass will be loose.
The original glass was painted black at the edge but this paint work does not peel off. You'd have to scratch it with a cutter for it to come out and still it's fucking hard. The one I sprayed comes out just by thumb rubbing it.
Anybody knows of another technique that I could try?
 I made the Wacom logo hand painted with a silver Sharpie in the inside side and then sprayed the black paint
Over it. It looks so great it is a pity all this effort is worthless
9  Screen Tablet malarky / Heyaaaalpppp / Re: ExpressKey Remote with old wacom drivers on: October 24, 2017, 03:23:14 AM
I have a ExpressKeys remote that I have been using for long with my Intuos Pro L with the same drivers. I have also tested it with the Cintiq 21UX DTK I'm trying to revive and that is from the same period of the Intuos 4. It should also work with an Intuos 4. I have not tested it yet but I can try tomorrow.
About the Intuos 2, I'm afraid it is too old so the drivers for modern tablets don't cover it (or the Intuos 3). You could try and install both drivers but I'm not sure if this would work since Windows will probably believe they are two versions of the same driver and not allow both drivers running at the same time.
I have also tried both the drivers of intuos 4 and a Bamboo and they both can coexist in the same computer but they are two different drivers so there is no conflict for Windows.
I think one thing worth trying would be to hack the intuos 2 driver so Windows identifies it as a different driver so you can install and use both. The driver for the intuos 4 appears in my computer as the service "wacom professional tablet driver" while the Bamboo driver appears under a similar but different name. If you manage to hack the intuos 2 driver so it is identified as a different driver/service/whatever, maybe you will be able to open both Wacom control panels to configure both devices separately but working at the same time.

I went the easy way and bought in ebay the inners of another Cintiq. It was the LCD and sensor cage with the 3 motherboards on it, so it was very simple to remove my faulty motherboard and replace it with the working one. Cintiq repaired except for one terrible mistake. While I was cleaning the glass of the front case in order to put the LCD in place again, I BROKE IT!!!

I was not doing any substantial pressure but it was enough to crack the glass. This glass is a 1mm thick glass with an anti-glare filter glued at the back. The filter is not at the front of the glass where you put the stylus but at the back, between the LCD screen and the glass. I think this filter also acted as a reinforcement of the glass, avoiding it to break when pressed from the outside, but when pressed from the inside (that's what I did) it simply cracked.

So now I have a working Cintiq but with a broken glass.  Cry

So what I want to ask you is what would you do?

I was thinking about replacing the glass with an acrylic sheet, more flexible but more prone to scratches, but I could also buy a screen protector to cover it and protect if from scratches, but I can't find a 1 mm sheet of 39 x 48.3 cm. The same goes for the plastic used to frame water paint pictures (2 mm and expensive) or glass (3 mm)

As I wrote on Drewid's topic:
One more thing. This digitizer contains two boards and flat flex to connect them.
You show active board (lot of chips) but not passive board (antennas). Flat cables shouldn't cause problems, but connectors at both ends may.

I'm not sure but in case there was any problem with the connectors for the sensor array, I think the detection of the pen would be erratic, being detected in some areas but not in others. But in my case, the pen is not detected anywhere.
12  Screen Tablet malarky / Heyaaaalpppp / Re: dropped 21UX 2nd gen not responding to stylus. on: August 17, 2017, 02:50:50 AM
As I see, digitizer board have two main chips and strange connector to LCD board.
First chip, lets say USB chip, working fully or partially. USB and buttons working. Communication with second chip may be broken.
Second chip, let say Digitizer chip, may be broken or waiting for signal from display controller.

IMHO both boards may need repair.

U5 is M16C R5F36CAMNFB and is the chip connected directly to the USB D- and D+ signals (through resistors). It is a microcomputer with its own memory, DMA, etc commonly used in USB devices.
U6 is the Wacom chip W4027F. This is the chip that locates the stylus and processes the signals from it. It is also present in the Intuos tablets.

Here are a couple of HI RES pictures I took of the motherboard using a scanner:

Hello again.
Here are the pictures. I took several more pictures than needed just in case they help to somebody else needing to disassemble a DTK-2100.









I have checked the connection between the Cintiq motherboard and the Display controller, not only pint to pin but following the tracks to the first component connected to each pin and it is OK, so the problem MUST be located in the Cintiq motherboard or the sensor matrix.

But in case the problem was in the sensor matrix, I guess I would get vertical or horizontal areas in the screen where the pen is not detected but not a complete lack of response everywhere.
15  Screen Tablet malarky / Heyaaaalpppp / dropped 21UX 2nd gen not responding to stylus. on: August 04, 2017, 07:55:07 PM
I have a second generation Cintiq 21UX DTK-2100 and recently in a very unfortunate accident it fell to the floor being hit in the lower left corner. Yhe plastic case in that corner broke in pieces but the LCD is still intact and working correctly. The Wacom driver still detects the Cintiq and all the ExpressKeys and ExpressSliders work but it doesn't react at all when I touch the screen with the stylus. (I have tried with several styluses, Grip Pen, Airbrush, Art Pen, Grip Pen Pro, Classic Pen but no way. All of them working in Intuos Pro, 5 and 4, of course).

So I think the problem is located at the tablet driver board (identified as PWB-B034D) that is still partially working since the device itself is detected and all the keys and sliders work. Or either in the sheet under the LCD that makes the EM matrix, but this is less likely since it is just a sheet of printed circuit matrix without any components on it.

I guess Wacom would charge me more than the cost of a fully working second hand 21UX for the motherboard so any suggestions?
The Motherboard has LOTS of test points but I don't know how to test it since I haven't found any information about it.
