I checked the batts, even tried new ones and still it wont turn on. Is there some explanation for this? I really confusing and i really would like to know the problem before i buy a new one

Check the battery contacts for corrosion - typewriter eraser pencils are ideal for polishing the contacts. The ON/OFF switch can fail - try pushing down as you slide the switch. The switch can be repaired for less than the cost of a new flashgun, as long as you don’t go to Canon that is…
