DWW-700M Touchscreen gone be crazy

**AIR-V** · 07-25-2005, 04:32 PM

Hello All,
I've got troubles with the touchscreen of my DWW-700M

. It works fine until a short time and after the cursor goes anywhere or sound blocked on axis.. vertical or horizontal....

I'm using Worcol driver...with this software there Draw section to test the calibrating. it can show me the troubles very fine. if i design a square the line don't follow the finger or pen.
What s wrong with it ??? have you already seem it before ?

Thanks
AIR-V

I have the same problem as:
Touchscreen defect ?

Problem is with the drivers methinks.

Tried the drivers supplied, and all drivers on egalax.

Egalax supplied drivers works perfectly on my mac (OSX 10.4).
<edit>I was wrong, the powerbook looses calibration after a few minutes in the same places the pc does</edit>

Been scouring forums, havent found a real fix with this.

Tried all combiations of drivers with fresh install, sp1, and sp2.

I get it working for about 10 minutes, then it will go back crazy..

Any definitive fix before I rma my entire setup?

my prob it's not because drivers...
when i receive my new dww-700m (the second one) .. i don't installed new drivers.. i just plug in usb .. and use driver used with my first defect screen ... (egalax 4.0)

the screen work perfectly .... during the first month.. after that.. some area of LCD stop to respond...

begin with the bottom right corner (square of 1/8 inch)
fews days later... (square of 1/4 inch)
fews days later... (square of 1/2 inch)
fews days later... bottom left & top right corner too...

my carputer is 100% finished .. so no new hardware .. except last week I plug usb mouse because my touchscreen don't work anymore..

after calibration (25).. work better.. except bottom right corner.. and I need to re-calibrated each 10 minute

sometime mouse pointer stay in top left corner.. don't want to move anywhere.. but i can click at (0,0) position .. woohoo..

sometime.. when i press somewhere and the mouse cursor don't move where i want to ... i can apply a stronger pressure.. sometime work.. sometime not..

i think some area of my LCD is frozen ..

my workaround: draw a LARGE SQUARE .. before trying to use touchscreen.. repeat this each 10 minute .. and before calibration..

looks like a real bad problem, i say try to refund and get your money back

This problem also has a fix. If you bought your monitor from me you can return it for repair. It needs a new touch panel. For those that want to do this yourself, I can send you a new touch panel. Here is a how to: http://www.digitalww.com/DWW700M_touchpanel.html

Wonder if ziplock will provide the same courtesy, heh heh.

Armen is very helpful with everything he sells, and backs it 100%. I hope you all get your problems sorted out, he made sure I got mine sorted out very fast.

i live in the UK and got one from here, same problem. can't send it back cause it would cost about $150 (£70) and couple of weeks with a hole in my MG dash.. the whole thing sucks if you ask me....
