It sounds to me like you’re thrashing; trying a bunch of stuff without systematically trying to figure out what is the root cause. To recap: You were able to get it to print by power cycling. It then detected that ink was out, so you tried to reset the waste tanks??? But that turned out not to be an issue. Then you refilled the carts and was able to print something, but the printout didn’t come out right. So, rather than do a cleaning, you tried alignment. And now it’s back to lockdown.
You need to come up with a game plan. Figure out what gets the printer to power-on successfully. Try power cycling it again. Once you figure out how to get it to turn on without blinking lights, proceed.
Now the printer is on, and you can print a nozzle check. It comes out smeared. This implies that the capping station and/or head needs to be cleaned. Follow the cleaning instructions provided by IJM. Once the nozzle check is clean, proceed.
Now that all nozzles are firing, align the head.
Finally, do a test photo print.
If at any time during this, all lights start blinking again, analyze. What caused it? Did the printer make a funny noise before the lights started blinking? Did you do something on the computer right before that happened? Etc.
