I have a HP Scanjet 3970 flatbed scanner that won't power up. I've checked all the connections and the power source and all se

Solution
If you tried a different cord, only thing you can do is repair the power board or replace the scanner.
Seeing how the thing is about 10 years old, I'd just replace it. Unless you know what to replace and how, you'll spend more on part and labor costs to fix it.
