My Vertex broke 3 years ago. It basically stopped in the middle of a print. I gave up fixing it and put it in storage (maybe hoping it would fix itself… ) Strange enough, it still has the same problems today. So I thought I try to fix it before I through it away.
When I turn it on there is no movement in any of the motors but all the lights on the stop sensors are red and there are some lights on the motherboard and the LCD glows. But there are no characters being shown in on the LCD, and nothing happens when adjusting the contrast of the LCD.
I’ve disconnected and reassembled the LCD and cable to the motherboard, but without any luck. I’ve also inspected the motherboard and the connections visually and by pulling them out/in again.
If I click the reset button on the motherboard one green light flashes, but nothing else happens.
The Power Unit is providing the 15V as expected. What else should I test?
