Sky-Watcher EQ5 SynScan is broke down

[MAKARON]

Hello everyone! I have result of my the problem! 

In begin of September, i sent the "Motor Control Box"  and the "Hand Control" and the "stepper motors" to repairman (he nickname @Ivan7enych - here his youtube channel https://www.youtube.com/c/Ivan7enych - this is not an advertisement, just maybe it will be interesting for someone, okay). He had defined problem. problem: two controllers TMC5130A is broken. We ordered these two controllers. Then Ivan7enych soldered them. Yesterday i had received package (the "Motor Control Box" and etc...) from Ivan7enych. And i happy! Now, it working! The Lamp is not flashing. No noise. Scratches on the reverse side insulated.

I hope next all will be fine.

The reason for this is still not clear to me.

1. there is a suspicion of such a reason: https://youtu.be/e4_SHT0iiXA?t=81 (there are subtitles) - that is, in my case (unlike the video) I could plug in the DC Jack 5.5x2.1mm power cable ( 12V / 3A) into one of the holes: HAND CONTROL / ST-4, and of course I DO NOT REMEMBER whether I did it or not, it was dark ... well ... now I have plugs in HAND CONTROL / ST-4 . and now I am extremely careful when I connect the power.
2. perhaps the reason is the "scratches" on the back of the board...

in general THANK YOU ALL! problem solved!

(it's a pity that the problem was not a cable break)

Glad to hear your mount is now up and running.  Strange how the driver chips had blown.  Still not important now as its been fixed.
