When I press the on/off button the screen lights uo and displays PENTAX, the lens zooms out but it gets to the end of it's travel and it sounds like a safety device is preventing damage by slipping the gears for a second then it zooms in again and shuts down. It seem like whatever limits lens travel is not set correctly. I've had a look inside but I cant see any stripped gears or broken/loose parts. Has anybody else experience of this ?
I have the same problem, when I turn on my pentax 57 optic the lens extends but it beeps and then retracts and shuts off. Any solution pls.!!!

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...ensure that the camera is turned on. If applicable, ensure the
lens cover has been removed before taking pictures. the LCD backlight
is turned on by pressing the DISPLAY button several times until the
screen appears. Depending on the camera model, the DISPLAY button may
be labeled as DISP or with a display icon. This button could be a
standalone button or it depends upon the camera model..... If operating the camera with a battery, ensure the battery is fully charged. Ensure the battery is inserted properly in the camera. If operating the camera with the power adapter, ensure it is plugged into a working AC outlet. Ensure
no Audio/Video (A/V) cables are connected for viewing pictures on a TV;
the LCD screen will not display when an A/V cable is connected. Perform a reset procedure on the camera....
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. 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.
