Replaced main board on my DTF 1390 and now control panel not working together powering up. The printer turns on, but the control panel never comes alive. How do I fix this, and why is a brand new printer dying on me in the course of three months?

Thank you for contacting us. We at BCH Technologies always appreciate your interaction and have a special place in our hearts for all the support you show us, be it on this blog or on YouTube. We need your feedback to improve our technical core.
Here are a few possible steps to find what is causing your DTF 1390 printer's control panel not to respond after changing a new main board.
First, let's discuss whether a printer can turn on or not. There is a main switch on the back of the printer. This switch powers the white ink management system and the printer. This switch always remains. If you turn it on, it doesn't mean the printer is turned on. To turn the printer on, you will need to push the control panel. You may hear the white ink stirrer and pump working, but it doesn't mean the printer is on.
Check The Main Board Works
Check Main Board: The replacement main board is functional. Occasionally, newly bought planks can be seen as faulty. Our quick guide to main board verification can be viewed here: https://youtu.be/6DlKiaZPGRg. The video provides a step-by-step guide to ensure proper operation of your main board.
Power Supply Check:
Check the Working of the Power Supply: Provide appropriate voltages to see if the power supply is correctly conducted. If you use a non-OEM power supply (like the Prestige A3+ R printers), ensure it is what your DTF 1390 printer requires. If not, please review our repair reference guide here and make sure all connections are good: https://bchtechnologies.com/products/reference-for-stylus-photo-1390.
Check FFC Cable Connectors:
FFC Cable Test: The medium connecting the Control panel with the main board is called a flexible Flat cable. This part sometimes needs fixing. Could you check that the FFC cable is inserted in the correct position and not pinched or broken? If the FFC (flat flexible circuit) cable is loose or damaged, power will not reach the control panel, and it may be unable to communicate with the main board.
Examine Wiring:
Check the Control Panel: If your printer has also been rewired, then the control panel will have some wires in it. The control panel will not power on if the wires are connected incorrectly. Follow your printer's wiring diagram to make sure all wires are properly connected and secured.
But printer issues can be hands-on, such as fixing a never-spit-out-paper-type jam or changing the ink!

Our service is to repair the printer as a whole or some of its parts and guide you on how we should proceed with mail-in / local drop-off options. We realize we might not be the most cost-effective, but if you are tight on cash, consider looking up some of these things via online research. You can first look on YouTube or visit the home page of our Channel (https://youtube.com/@bchtechnologies) and use a little notDatoire to check near "About." what is it there is always some search icon in all channels that lets you search for videos. This is usually the fastest way to find an answer, as many video tutorials exist. In addition, YouTube may recommend videos from other valuable channels.
