Calibration of touch Screen is off - Can't re-calibrate.
I have an HP Pavilion tx1000 (specifically 1308nr) that I bought from Best Buy. Recently the calibration of the pen became off by about 2 inches from where I touch the screen. My pen is not the electric type, it is only a pen-shaped piece of plastic. When I have tried to re-calibrate it the 2nd cross-hairs never register, the computer just beeps when I tap it (no matter the screen orientation). Although, when I first turn on my computer the calibration is perfect when I am on the screen wherein you type in your password.
I really appreciate your help!

1. Place letter- or A4-size paper in tray 1, and adjust the side guides. 2. On the control-panel Home screen, scroll to and touch Administration. 3. Touch Troubleshooting. 4. Touch Calibrate Scanner. 5. Touch Calibrate to print the first pass of the calibration target(Print out). 6. Place the first pass of the calibration target face-down in tray 1 so that the arrows are facing into the MFP. 7. Touch Start to print the second pass. 8. Place the calibration target face-up into the ADF, and adjust the side guides. 9. After the calibration target has passed through the ADF once, reposition it face down in the ADF and touch Start. 10. Place the calibration target face-down on the scanner glass, touch Start, and scan the page. After this pass, the calibration is complete. Calibration will fails if print quality is not good...ensure that print quality must be in order.. Once calibration successfully done, restart printer several times & verify start button light, if its green every time 'u' re success. if not cleaning required for CCD which is major work & not suggestable..
Calibrate the touch screenThe
command buttons and fields are displayed on the screen image at
specific pixel points. To initiate a response, the touch screen
interface needs to recognize exactly where a fingertip or pen touches
the screen relative to the pixel position of the display. Each user has
a slightly different hand-eye coordination response. Calibrating the
touch screen allows the interface to compensate between where the
program is expecting a touch and where the touch actually occurs.
To calibrate the touch screen, place the tablet notebook in the desired orientation and do the following actions.
Click or tap Start > Control Panel > Tablet PC Settings
to open the Table PC Settings window.
On the General tab, select the option to display the menus in either the Right-handed
On the General tab, select the desired screen orientation
from the drop-down menu, and click or tap Calibrate
. Follow the instruction to touch the screen at the specified points.
Repeat this calibration action for all four of the screen orientations, then click or tap Apply
On the Handwriting Recognition tab, select the Use the handwriting personalization
At a later time, you can return to review the Go to Pen and Input Devices
and Go to Input Panel Settings
options to make using the touch screen to control programs and input text easier and more accurate.

These TX1000's have their fair share of issues, and this one is the most costly (potentially) to resolve.
There are two, and only two, possibilities for why the digitizer in the LCD isnt working.
1) On many occasions, I'd estimate about 40% of the time, there's a little cable inside the LCD housing and behind the LCD itself that connects to a daughter-board, which then is cabled to the mainboard. This little cable sometimes comes loose, and a simple reconnect will resolve the stylus pen issues.
2) The digitizer in the LCD has failed, no separate LCD+digitizer purchase, oh no no no....Gotta get the whole damn assembly. Part# 441106-001 at roughly $550 exchange from HP.
Try using your finger to calibrate the screen at first. (If you have difficult to navigate to the alignment screen use the stylus & keyboard to feel out your way) when calibrated to an accepable degree use the stylus to calibrate the sreen, if the target doesn't respond to stylus at any specific piont use your finger. Continue this process till u get it aligned as best as possible. I suspect this problem is caused by specific points on the screen going bad.
Mine has already twice made the same thing. Solution was simple - got the touchscreen changed (luckily under warranty). As third problem required change of the motherboard, I'm planning to get rid of the piece of junk alltogether. I think it is a solution for all the troubles with tx1000.
I have the solution to the touch screen problem. You need to get the support and strip down document for yout touch screen from HP.. for instance the one for the tx1000 series is c00853874.pdf
you will need another machine or to print the pages required to strip your machine all the way down to removing the monitor, and the surround on the screen.
the document is step by step...label the screw etc, you'll be fine...even if you have never done it before.
the result is the terrible build quality of the machines. the ribbon access cables for the webcam, and for the touch screen are poorly installed.
I found that my touchs screen access cable was not actually properly installed at all, and was only barely contacting when i received the machine.
my touch screen is working properly, you need to be gently with everything, the circuit board that the webcam and the touch screen connect to is directly behind the screen..
you must strip the screen down, and then lift the glass... there are 4 screws around the edges of the glass when you have it stripped down... once you lift the screen up.. there is a circuit board on the rear of the top of the plastic screen back. the are connectors going into this...for the quick access buttons around the screen edges...the webcam,.. and the touchscreen.
i have to say i just discussed this with a guy called GINO on Hp online support...and he doesnt care that this is the solution...or that there has been a manufacturing fault since day on.. they never plugged the cables in properly.
