GTM32 CONTROL BOARD
After mounting it and after some tests the printer was working well. During a last test the carriage stopped and the LCD screen switched off.
After this incident, the LCD screen does not switch on. When I plug and switch on the PSU the LCD screen flickers for a moment, but does not switch on. Besides the PC doesn’t recognize the COM port since the incident. Before that happened, with the PSU turned off, the LCD screen flickered when I moved the carriages manually up and down due to kinetic energy that the motors produced. After the incident the screen doesn’t flickers when I do this.
I have also checked the PSU and it seems to be right because the LED light turns on when I plugged in the PSU. I think the problem is that the control board has burnt. I have tried contacting by mail with techincal support email@example.com and feedback Rita.firstname.lastname@example.org but the mail always fails in sending. I've also tried buying a new control board, but the GTM32 pro control board doesn't appear on their online catalogue nor other online shopping websites as amazon, aliexpress or ebay. Can anybody solve my problem?
