bypassing the touch screen calibration

33 posts in this topic

Posted

Hello!

I have smashed the touch screen on my qtek9090(not the lcd), and used a program to control my pda with the joystick. But when I hard reset it, the calibration screen shows up, and i can't bypass it. Is there a program, or something like that, to bypass it?

I got the digitizer from fujitsu siemens loox600, its sizes are identical to the qteks 9090, will it work, if i change the original with this one?

Thanks!

Just a guess, but you could hook it up to the PC and setup ActiveSync. Then run the "ActiveSync Remote Display" power tool to use the mouse to control it. My guess is that this will get you past the calibration screen, but there is a chance that it won't work. "True Connect" is similar and might work as well.

Worst case, you should be able to get some debug utils for ActiveSync that let you kill remote processes on the device. You could use that to kill the calibration screen, but I'd bet it will reappear on the next boot. You might also need the full Visual Studio development environment to do this, which might not be an option for you.

WRT replacing screens, I believe there are three different screens found on the Blue Angel, and one of them is incompatible with the others. This is from memory, so don't take it as gospel. With screens from another device altogether, it's a maybe but you'd need to be a lucky person to get away with it!

If the dimensions are the same and the ribbon cable can be soldered on no problem, yes it would work. I have transplanted a digitiser between the two different types of sony / toppolly blueangel LCM's and after splicing the ribbon wider so that the contacts matched up, it worked no problem.

If you do not manage it I have spare digitisers for the sony screens with the narrow ribbon connector.

sell digitisers as well, but they do not state which LCM they are for :-(

Ah! Das macht meir leid....or something.

If you can seperate the tension film plastic from the glass *with the silver strips in place* it *may* work if you transplant it to another digitiser glasstop but I have never managed it so I usually just throw them away. You cannot use ordinary glass. If you do not get the height of the plastic film correct it will stick to the glass somewhere accross the screen and will not work as the touchscreen works on tension / resistance so if it is touching at points other than the sides it cannot register your input.

If you can tell me the part number of the screen I will be able to help more.

It looks similar but the blueangel has a metal frame with 4 mounting lugs on it.

I'm in the UK. The screen number will be something like 60H000024 / or

ACX 502 BMV but I'm just made those numbers up so don't worry if they are not the same.

http://www.pdasmart.com/products/XD20pdaphonexda2s.htm well, it seems that it is the right digitizer. Now i just have to take it apart to see the number.

Thanks!

The picture they have used is a file photo, the digitisers I have seen on blueangels are not green tinged around the edges as theirs is shown to be.

If you look, they use the same picture in the ipaq section:

This is how a bypass is done!

Here you go theses are simple steps to bypass the touchscreen alignment.

Install you activesyn blah blah blah when it finds it go on my computer and go into your PDA device

go to windows startup and delete the Welcome file

after that give your PPC a soft reset and BAM u by passed the screen now get a free desktop program liek pocket controller from the internet it will automatically install on your pda and BAM you can control your pda add music and whatever

but now if you want to click stuff on the road get pen irazu just search on google and send it to your PDA then go to file explorer and double click it and you got a cute little mouse program that you can use like a stylus

On a sticker, on the back of the LCM assembly.

FYI, on the left is the digitiser from a toppoly LCM, on the right is one from a sony. Notice the ribbon on the toppoly unit is wider? You can cut the sony ribbon and open it out to fit a toppoly LCD if you have to but it is a bit tricky. The metal frame doesn't quite fit either but with some work it does.

I only have sony digitisers.

Sorry, only you can answer that. It may be worth you paying someone to do it for you - if you really need it?

Maybe take it to a repair shop if this is too difficult? You will find swopping the digitiser *very* difficult if you can't get to the LCD....

Instructions are available on that other forum you posted on about this problem

Well, I called the distributor, but they only sell/change the lcd+digitizer and want around 300$, so I have to order only the digitizer from somewhere else and than hope that they will change it. I will try to open my pda again tomorrow, but my hopes aren't high.

I'll change the digitiser for a fee if you want to send to the UK, but the Qtek 9090 can have either the sony or the toppoly screen in and I only have sony digitisers.

Sorry! That's a toppolly LCM with the wider ribbon :-(

It is possible to fit the digitisers I have to your LCD but it is difficult and I'd rather not do it as I burnt my fingers the last time. :evil:

I do not have toppolly LCMs or digitisers but I have many 06 boards waiting for them - they are heard to get hold of. Any company who says they can supply 'blueangel' screens ***ask them which type*** as you cannot fit them to each other.

It may be cheaper to sell your 9090 on ebay broken and buy another :|

Well, buying a new one is out of the option, since I saved money for this one for a lot of time.What about this page:http://www.goldenbyte.com/ ; the owner says that he has the right one.

How much work needs to be done to fit the sony digitizer?

Don't assume they will have one. They have used the same picture of a digitiser as PPCTechs page! Email them to ask.

You could make the sony digitiser fit. As explained previously you need to slice the ribbon along the tracks to make the narrow connections fit over a wider area as below.

Then you have to hold the ribbons in the wider pattern and heat the contact pads to solder them in place. Don't take it personnally but if you have to ask how, then I wouldn't attempt it, you may end up destroying your LCD ribbon :cry:
