Hi, just landed into CN
I've got a ETX70AT a couple of decades and last two years it has been parked
Let's see whether I am able to explain the symptoms and some findings.
Yesterday I decided to start it up. I connected a 9V power supply to it. When it started up, during alignment it gave a motor failure error. I restarted several times and there was no way. I increased the power supply voltage to 12V using a regulator (since it suggested that the voltage was not enough) and it started to work better, however while it was moving during the alignment I could see that it was having a hard time, and it even stopped. I could not even hear the movement of the motors to maintain the position once a star was located.
I decided to continue manually with the tripod without unlocking anything.
This morning when I started it up, the Meade message appears as you can see in the video (https://www.facebook...978394704185663) and then the image fades and it looks like a movement on the display, but the motors are not heard and the remote control does not act.
I decided to disassemble it (first time) and I found the declination motor broken (I already found STLs to print it out in 3D). Also I looked into the pcb and did not find any noticeable in the connections but AUTOSTAR does not work.
I will be grateful if someone can give me some idea how to proceed. I will be searching along CloudNight messages to determine the problem although I am not sure about it.
