We are stuck in ZOOM. No one has a head!

A good possibility is the zoom head is causing the clicking sound. As we zoom the flash, the inside of the head moves to the back and forward. Gently tap it a few times see if that helps. My guess is it needs servicing.

I had a similar problem with my 430 EXII flash recently and discovered that after using the flash head in a "bounce" orientation, where the zoom automatically sets itself to 50mm, It wouldn't go back to wide angle or telephoto when I folded it back into place. The problem was caused by a small piece of confetti preventing the head from fully resting in the forward position. Check to see if there is any debris caught in there.

Not all TV programs are broadcast in 1080. When you use zoom or stretch on a program in 720 or 480 and a 1080 program is viewed you have to go back and take off zoom and stretch to get a correct picture.

On a webcam, you will generally find that they don't have the optical zoom that you would find on a compact digital, or SLR camer. in most cases, the zoom that you have is digital zoom, this just increases the size of parts the image being fed to the computer, and will often become blurred after a certain point. the best advice would be to move closer to the cam, or to buy a camera with higher resolution...generally 5MP should be more than enough.
the other thing you should try first, is to check that the camera isn't out of focus by looking for a ring around the lens, on some models there will be an adjustable focus, if this is the case,rotate the ring until a desirable image is shown.

Your zoom motor is probably stuck. Remove the two screws on the front side of the tiltable head. Pry off the two tilt caps using a small flat head screwdriver (they are glued on). Remove the 4 screws found under each cap. Now you can separate the two sides of the head and take out the two lenses (remember exactly how the lenses were positioned). Try pushing the flash in or out (it should move with a little force). See if the flash now responds before reassembling.

Check your cable box remote. You may have that stuck on stretch or zoom. Look for "ASPECT" above # on remote.

I paid the expert fee yet never got the answer to my Haier 27 inch Flat screen TV
So don’t hold your breath

on your remote try this..... push the left or right arrow keys to change format

don;t know what you mean by they came to calibrate it? if someone worked on it and now it does this then have them come back and undo it
