@Digerati first of all thank you for even replying.
So yes - I contacted the Seller and he was responsive and explained that the unit was working at time of pulling and selling from school network because of upgrades. The team that pulled it says it was reset. But I tried with VGA cable to 2...
Purchased as supposedly working unit on ebay but upon starting with the power cable on, all I get is blinking green power led with consistent rate which means booting phase. After waiting for even hours, the blinking continues.
I have tried to connect vga cable locally and also null modem cable...
