Hello,

I am looking for some help to diagnose my Hyundai hit18s. I have had a fault with no boot and was suspect power supply. I took to repair shop before Christmas and they identified a fault and I got it back today, installed it in the machine and I now have more lights on the control but still no boot up.

in order for men to try and read the faults from the 7 segment display I am trying to understand the components that build up the control.

I have 2 seven segment displays in the cabinet but do not know which component is the cpu and what the other one is.

I was to try and understand the fault to determine if to pay for an engineer visit. I do not want to spend too much money on this machine. I only use it occasionally.

from left to right I have board next to the pier supply with the memory battery on that had=s a display with '8'

further to the right I have another board with a display reading '0'

any help appreciated

Screen is blank does not try to boot
