Man,it doesn't sound good. Just to make sure do these 2 things:
1) Power on while holding reset and see if you can get to priiloader
2) power down and power on again with all discs out and see if your dvd light flashes once, or twice quickly.
Without those fail safes you might be in a pickle unless you have a nand backup and your wii is old enough to support bootmii as boot2. Good luck!
edit: depending on what system menu you were on a modchip preprogramed to autoboot might work as well since you haven't used it in a while as long as your sm ios is in tact
