Ireland | jbweston - 2/17/2011 02:34 Something must be seriously wrong with it. When I depress all 3 buttons as directed, it just boots on up normally in another split second. I hope my dealer returns my call soon.
A couple of points easily missed, when calibrating in a hurry it is easy to not hit the one of the points in the centre and you will find yourself starting over!When doing a reset it is when the second progress bar is over half across that you press the buttons. |
| I provide replacement touchscreens for broken or unresponsive to finger touch. These are brand new genuine oem replacement touchscreens for a Trimble 750 FM CFX Display. If you do not feel comfortable to perform the repair after reviewing my tutorial, I can perform the install for you. Turnaround time is roughly 1 week. Just pay shipping both ways.
I also supply other replacement touch screens for various other models such as the Trimble FMD, Ag leader Insight, Versa, Kinze Vision. The ad for these screens are listed here: Insight, FMD, Kinze Vision
I will provide some installation guidance below if needed.
Install time takes 20-35 minutes. (Depends how quick you can turn out torx screws)
Touch screen calibration is required after booting up the display in the settings menu.
Be sure that the display is at room temperature before doing the installation.

T15 Torx bit
Phillip Screw driver
Flat Plade screw drivers
Take your flat blade screw driver and remove the rubber side guards as depicted. They pop right off with a little force. You will notice a torx screw is hidden underneath these rubber guards which needs to be removed.
Use torx T15 to remove all screws from the back
Remove this connector to to allow separation from the back enclosure.
1. Disconnect this ribbon cable circled in pink. This is the touch panel's ribbon cable
2. Remove all torx screws circled in yellow
3. Now lift the assembly away from the front bezel
4. Clean and wipe any dust and debris build up from the front bezel
5. Pry the defective touch panel evenly away from the LCD screen. Pry with gentle force. Take your time. Eventually the panel will peel and pop right off.
1. Lay the new touch panel onto the front bezel in the correct orientation so that the ribbon connector and be installed. Try to lay the touch panel onto the front bezel as square as possible.
2. Lay the LCD assembly on top of the touch panel while also keeping the torx screw holes lined up.
3. Evenly tighten torx screws in a criss-cross fashion. Do not over tighten!
4. Reconnect the Ribbon cable for the touch screen panel circled in pink from image above
5. Reconnect the Cable circled in yellow from image above
6. lay the back enclosure on top and fasten the remaining torx screws and press the side rubber guards in place.
7. Power on device and go into the calibration settings.
There is a short cut to get to the screen calibration by pressing and holding the power button and to top brightness button during the boot-up loading screen during the second loading progress bar once it reaches just passed 50%. This is considered a "Soft Reset"
Soft/Hard Reset
If you can't get the short cut to work, getting to the calibration menu can be a little tricky since the new touch screen won't be calibrated. You may have to press "blindly" around the screen until the touch screen can find the button you wish to press. Example: You may have to press an inch away to the left or right, above or below of the button you wish to press. You may want to use something more precise such as the end of a pencil eraser or a stylus pen during calibration. Once calibration is complete. It should be good as new.
This is my technique of replacing the touch screen. These instructions are here to help you build confidence in doing this task. However, I am not liable or responsible for the success of the installation.
A unique symptom of a faulty touchscreen is also when you initially bootup the display and you reach a screen "Finalizing firmware upgrade" "Please wait while the display finalizes the firmware upgrade. This process may take a few minutes." You then get to the point where your finger presses are also not recognized. The touchscreen has "shorted out" and caused a problem with the bootup sequence. A new touchscreen will also fix this problem.
