Hello Rmaratha2,
I am in the UK.
I have Alchemist Script miner for LTC.
About 4 of my boards are down and need a repair.
I think the asic's are OK, it is the Power Supply side that has burned out.
I have the schematics of the circuit layout, and I think the parts that need to be replaced are TI type 86360D Buck FET power blocks. These need to be reflow soldered.
Maybe the Zener's have been zapped too.
Each board has 4 modules, each comprising 2 Buck FET's and 2 Zener diodes and a bank of 8 asic's.
As I said, I think most of the asic's are still OK, and that it is the power input stage that has been fried.
Of course, that is only my ( educated ) opinion, I have not got proper facilities to do a circuit test in order to diagnose the true cause of the problem.
Do you think you can help me ?
I can pay BTC or LTC or bank t/f. ( or do you want some old 500 Rupee notes ??
)
Please pm me. thanks,
-Erich
