Thank you for reply.
Actually, when Capacitor exploded, I connected 12v on demultiplexer to 12v (just above the LCD connector) on megatronics not 12v 5A socket. It’s bcz I didn’t much knowledge abt electronics.
And I tried connect 12v on demultiplexer with 12v 5A on Megatronics, but in that case the Megatronics doesn’t turned on. Megatronics is connected with power supply by only 12V 10A socket at that case. That’s why I made wrong connection of 12v with megatronics.
So, my question is that do I need more connection btw megatronics and power supply except 12V 10A for turn on the Megatronics?
Thank you.
