[langtitle=es]Pentax km - Sensor cubierto.. no puedo hacer fotos[/langtitle]

Buenos días,

Desde hace unos días no puedo hacer fotos con mi pentax km. Todas las fotografías salían totalmente negras, y después de estar trasteando un rato descubrí de donde creo que viene el problema.

Al quitar el objetivo y poner en modo limpieza del sensor y subir el espejo, descubro que donde solía estar situado el sensor aparece una especie de cortinilla de plástico, dejando el sensor cubierto. No sé de qué forma se puede hacer para que se mueva o cómo solucionarlo.

En alguna ocasión he tenido que limpiar el sensor porque se me habían pegado motas de polvo o algún pelo, pero nunca había tenido problemas con la limpieza.

Muchas gracias por todas las ayudas!!

At the risk of stating the obvious, the 'curtain' sounds to me as if it's the shutter, stuck down. As to what to do about it, I'm afraid I do not know.

Yep, sounds like a stuck shutter. Recommend only 1 course of action. Send in for repair.

There is one thing you could try, before you send it in for service. Its a long-shot, but who knows? It might work.

First, find the menu option that says something like "Reset to factory settings".

Then, remove the batteries and let the camera sit overnight.

Re-insert the batteries and try again.

I have no knowledge that this will work, but it costs nothing, doesn't take very long (certainly less than sending for service) and since a modern dslr is basically a computer with a lens, it might work. Its a variation on the old Windows "power off/power on" trick that often works with PC's.

Good luck.

Also try a firmware flash, that has been known to correct some strange problems.

I'd be cautious about sending for repair, since estimates alone can cost a lot (especially considering shipping), take a long time, and repairs can easily reach the cost of a replacement camera. You might just try the suggestions earlier and then give up if they don't work.

Muchas gracias por los consejos. Estos días he estado intentando la mayor parte de lo propuesto, el disparo largo, restablecer los valores de fábrica, y finalmente actualizar el firmware, pero no he conseguido que eche ninguna foto...
tendré que ver cuanto me cuesta repararla..

try taking a shot with the built in timer... this automatically lifts the mirror and might bring it down automatically if the mirror is the problem
good luck
