Lens cover i dropped my camera for the first time in the sand. i guess grains of sand got stuck inside and the lens cover will not open fully. i've tried compressed air. any other ideas?

A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it. There are many non-invasive techniques that people have come up with to accomplish this. Some may be seen on this blog article. You can also open the lens barrel up to fix the covers, but only as a very last resort. This article provides further information on correcting this problem.

yes its grain or sand only stuck in between the lens.

are you experienced in electronics for opening the camera?

It's usually merely a grain of sand or dust jamming it. But it's also usually easy to fix. This link outlines repair techniques for a stuck automatic lens cover. Recommend trying the less "risky" ones first before considering the end of the lens.

A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it: 1) Try blowing lots of compressed air around the lens cover to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Use no heat mode if possible. 2) Slide a thin strip of paper between the lens cover shutters and the outer support ring. Work it around 360 degres to clear out any debris that may be in there. 3) With the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. Repeat the above three steps several times. If repeated tries don't work (keeping in mind that it usually does), it then may be necessary to open the lens barrel to access the lens cover mechanism.

You can open the lens barrel up to fiix the covers, but only as a very last resort. The above procedures normally work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and it will void your warranty).

Try blowing lots of compressed air around the open lens shutter to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Also with the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. A grain of sand in the mechanism is usually the culprit, and you want to try to dislodge it.

You can open it up, but only as a very last resort. The above procedures usually work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and it will void your warranty):
