1  Screen Tablet malarky / The Trading post / Intous 3 A3 Wide and New LG IPS 226V sheffield UK on: October 12, 2013, 09:52:18 AM
Hi,

I have for sale an intous 3 A3 wide and new IPS226V monitor for sale.
Also spare led strip and controller from an IPS 226V and extension ribbons for LVDS and LED power.

Everything you'd need to do a builld.

As you can see I completed mine the first time (see working pic)
but recently had an accident and damaged the screen of my first LCD.

I had originally bought a spare IPS226V monitor in case something went wrong during my first build but never
used it.

I do not want to make another build so selling up.

The intous 3 A3 wide has

Top cut for LCD...
Inside ribs on inside of case base taken out.
Some holes in the bottom of base.


Looking for an reasonable offer on this...

Pickup only from Sheffield UK.

3  Screen Tablet malarky / Design issues / Cintiq shielding on: December 30, 2012, 08:02:29 PM


So thanks to wchestnutt for posting the pics showing his cintiq from inside.

http://forum.bongofish.co.uk/index.php?topic=2236.0

To me it looks like a custom size wacom tablet board around the same size as the screen they use. It seems this is put behind the diffuser much the
same as we do in our builds but they can then package it more efficiently by putting the metal sheilding next and then folding the lcd flip out board over the
metal shield/panel...  then they put some wierd copper on the FFC's along the top edge where the lcd flip out board is at.

Ok we can't get hold of custom size wacom boards ourselves but was wondering if we can use the above to make out shielding better?

Have you any freinds that might have another 21ux?
if so it does not seem that hard to swap out the screen contoller board?

Its a shame mate...  NEC ips display probably... 
I can't see the pics, have you posted them?
I was certain it was one of the LVDS or other ribbons that might have come out of the connector.

If you decide to sell it and you're near sheffield or birmingham I can buy and collect and give it a try.

From the details you posted above you are correct this is not an issue with you computer or graphics card. So this leaves a few possibilities I can think of;

1. The LVDS cable from the LCD controller to the LCD driver is not fully inserted and just needs pushing back in.
2. One of the ribbon cables along the edge of the LCD has come slightly away from the LCD glass, although my gut feeling on this is that this is unlikely as you usually see lines on the screen rather than a change in colour on one side. If this is the case it may not be possible to fix.
3. The VGA/DVI cable has come loose on the inside of the Cintiq and needs pushing back in or resoldering. Having not seen inside one I'm not sure how it will be connected.
4. Might be a power problem, dodgy capacitor perhaps. Should be obvious if this is the case as they often bulge and may leak goop.

I think you need to make a decision as to whether you feel able to take the screen apart. As far as I can see on the net nobody has attempted any kind of repair of mod/hack with a Cintiq and documented it so we are all limited with the information we can provide.
My honest feeling is that you should go for this and try to fix it, the fact that you have seen the screen working makes me think it should be repairable and probably not too difficult, additionally I would love to see some photos of the inside of the Cintiq, who know's you might be able to help us with the fight against jitter!! 

My gut feeling is that this is the problem.

TBH i hav'nt seen one of these open so can't advise. Doing a quick search i can't see any guides either...

One thing look at your DVI connector and on the cintiq see if you can see any bent pins or anything like that.
Also try pinching the DVI cable in different places.

The heat is probably from internal components like you suspect, i doubt its the cause of the problems.

I've destroyed two screens trying to make a DIY cintiq... some of the FFC's are very very fragile, particulary the
traces at the sides of the screens and on the flip out circuits behind the screen.

If you do try to fix it be very very careful, not just taking it apart but also around any of the ribbon cables.

Looking through past posts most people do tend to wreak a screen or two making DIY cintiq's.

having said that...

I'd take a punt and fix it myself for £150 anyday....  I've gone though £450 worth of components already.
If i had to do it all again I would get a 21ux like you've done.

How come you're only getting most of your money back?   

How much are they keeping back?   this would determine if its worth taking the risk and trying to fix yourself.

If it was mine and I had no alternative i'd try to see if an ffc has worked loose. It'd be tricky because some of the screws can be hard to find
and ffc's can be hidden too. If its not this the other stuff can be hard to fix...

Try looking for a guide somewhere on the net.

If you hadnt thrown it away I could have offered you some money for the broken tablet.

Also are the circuits for the oled displays and buttons the same for all intous 4's

Maybe it would have been possible to buy a little intous4 and take out those components to replace in the xl?

11  Screen Tablet malarky / Build Logs / Re: Tabletmod XL HD build attempt on: December 29, 2011, 02:50:21 PM


I am sorry to hear of your bad news Mhage.

Is your intous 4 totally dead? or just one of the OLED buttons/display windows?

Post a pic of the damage maybe it can be repaired?   or if you don't feel comfortable maybe sold for parts so you're not
totally out of pocket.

Yes its probably the tangled wires thats causing interference.
I had some interference when I tried to shield the ffcs with aluminium tape.
I had take the aluminium tape off again.

This screen is very suseptable to interference particulary on the lvds ffc.

Its good practice to use flux remover so I just use it when I can.

I have intous 3 A3 wide and I get a little jitter with this build. I am going to try sheilding it when I get a new monitor but 1'm not sure its going to go away.

I don't know if the jitter is due to the 4mm temporary glass I have on the moment or something else.

When I was doing my build I noticed to very very little jitter ( I was just using a think sheet of plastic at the time).

I am going to put lexan 2mm on at some point to see if the extra few mm I gain will effect this.

Where abouts are you located dragon?

Yes do not remove the metal back plate or the foam from behind the wacom sensor board. Without it there performance will be effected quite a lot and you'll get all sorts of
weird stuff happening to the cursor.

To get my monitor screen in to the board, I had to cut the top plastic on the wacom board to the same size as the screen I put in.

On mine the screen is approx 8mm thick with the diffuser so it will stick above the plane of the wacoms plastic a few mm's but this is not a problem as we have
plenty of headway before the board cannot sense the pen.

At this stage you would cover the screen with some protective sheet. I am thinking of using 2mm thick lexan.

Yes this is exactly what I did.

The pressed metal sheet has raised sections that clip into the plastic black frame to keep it in place.

I used a dremel to carefully cut the metal sheet near the led.

The led sits in a groove in the cut metal piece as it originally did and everything is aligned perfectly with the diffuser when this modified peice is clipped in the black frame.

See the pic showing led bar and the cut metal frame.
