Not much of a difference in my opinion. But check your powerboard schematic to see what voltage value is required at the pins. If the tv is completely dead but you are getting these voltages from the powerboard, then its likely the motherboard has the issue. Also Test the tcon board for any output voltage. Hope it helps.
Good job!
Where you bought the main board
I searched on ebay and got one. You could also look around the black market on facebook for a cracked screen one.
I have trouble with it but when i tested i have 17v not 18v what does it mean ? Thnx for advice
