Got my Pentax Optio A10 soaked in the rain today. TOTALLY!

This happen after a hard hit on the floor

Since the screen went black BEFORE the lens retracted, it makes me think this is a main board problem. The only other possibility is that it is the lens assembly, but since it went black BEFORE the lens retracted, I don't think that is it. I can replace the main board for $40, or you can send it to pentax in Arizona, and they will do it for about $90.
The main board is NOT something that I would suggest anyone try to replace as a DIY project. There are too many small screws, and delicate connections to deal with.

If you just want to sell the camera as-is, I also buy all pentax a10, a20, a30, a40 cameras, in any condition.

Hi,

You can download your manual here:

Hope this helps!!!

You can buy a screen on eBay for about $25 shipped, and it will come with instructions. If you are handy, and good with small parts, this is an option. If you prefer to have someone else repair it, I will replace the screen for $40. You could also send it to Pentax in Arizona and they will replace the screen for about $90.

It sounds like you need a new main board. Pentax in Arizona will replace the main board for about $135, or I will replace it for $65. If you just want to get rid of this camera, I also buy all Pentax Option a10, a20, a30, a40 cameras.

hi i bought a canon powershot 780IS and it isnt powering on..the lens came out then the whole camera shut down...nothing works and the battery is fully charged..

It sounds like you may have a bad lens assembly. If it is sticking, it will buzz. If it fails to open all the way, it will turn itself back off. This is what it sounds like you are saying. I can fix this for $40, or you can send it to Pentax in Arizona. I don't know what they charge for a lens assembly, but the minimum charge for this camera seems to be about $90. If you just want to get rid of this camera, I also buy all Pentax Option a10, a20, a30, a40 cameras.

It sounds like you may have a bad lens assembly, but you did not mention if it seems to be fully extending or not. If it is sticking, it will usually buzz. If it fails to open all the way, it will turn itself back off. This sounds like what may be happening. I can fix this for $40, or you can send it to Pentax in Arizona.

Try the procedures in this tip.

The battery should be a common format with a Pentax label. There is a possibility it could be card fault. But before you rush out to buy a card[not a bad idea to have two cards though] Contact Pentax Tech Support site - this may be an on going issue- and the camera is young enough to be swapped under warranty.
