Issue
I have an older model DCX-250 that the touchscreen has dead spots on the screen but the main board and power supply are working fine. It was wondering if the newer touch screen is compatible with the main board and power I have for the older model DCX-250
Environment
DCX - 250
Cause
When replacing DCX250 Touch Screen in the field you must check compatibility of your Main board.
Resolution
The black inverter located on "U6" of the Main Boards PCB was changed out to a newer inverter. The old style inverter will not work with the Touch screen.
If you have the older inverter labeled E205-E821D then this will need to go back to repair to fix because the Touch Screen will not work with this older style inverter. If you have the black inverter that is labeled E2536 it is newer and you can just order a new touch screen from customer care.
