My problem with 430EX II: - no red light on; - pilot button does nothing / doesn't fire; - doesn't fire on camera; - camera fire button only activates the distance measuring red beams; tried brand-new batteries, cleaned it really nice - still nothing.

Hold down the menu button while camera is on.

SOURCE: Flash Will Not Fire

Try a mode other than auto, and turn off the flash. Then try taking a picture. Did it work? If so, then your flash is either shorted or burned out, or the flash safety circuit thinks that the camera is open. If the flash is burned out, then professional repair is required, as a flash change-out is not trivial (Call 1-800-OK-CANON).

However, it's more likely to be only a break in the safety circuit. Many Canon cameras use some of the screws in the camera case to serve as a means of detecting if the case is open (and thus disables the flash to prevent shock). Examine all the screws around the perimeter of your case. Are they all there and tight? If not, tighten loose screws and try moving and replacing any missing screws with one of the others that are still there.

SOURCE: I just bought the 430ex II flash and it won't fire

I assume that flash is turned on. 430ex flash will fire automatically only in AUTO mode. On manual modes you mus manually force the flash to fire.
If flash doesn't fire at all, consider to claim the vendor or let the vendor to check the flash mounted on your camera.

Hello

Sounds like the flash tube has gone.
It should be taken to an authorized repair centre for a repair estimate.

I had the same problem with new batteries reporting as "low" and instant shut-off. After I found that it would stay on when plugged into USB, I suspected a firmware bug in the camera (I am a computer engineer). So I thought "how can I fool it?" I then found that it would stay on if you power it up with the rotary dial BETWEEN the video and manual ("M") setting -- in the "illegal" position. The after it's on, every mode works!
