mourgos Posted August 15, 2016 Share Posted August 15, 2016 <p>I recently purchased on eBay a Pentax 645N. It looked pretty new in the box. The only thing it is does not work.</p><p>It has a fast 2.8 lens. The batteries are Lithium and new. The battery indicator light blinks no matter how much I clean the battery connections. The battery holder tested as 9v yet flashes.<br>The camera makes a whine when I press the shutter and then stops, with indicator flashing.<br>I'd like to see if there is a quick fix.</p><p>Thanks!

john_shriver Posted August 15, 2016 Share Posted August 15, 2016 <p>I know the Pentax MZ series have a separate motor just for the mirror, and the gear on it is plastic, shrinks, and then cracks and spins on the shaft. Causes the same sort of symptoms.</p> Link to comment Share on other sites More sharing options...
john_shriver Posted August 16, 2016 Share Posted August 16, 2016 <p>Two choices. Return it for refund. Or pay <a href="http://www.pentaxs.com">Eric Hendrickson</a> to repair it. Risk of the latter course is that it's not repairable.</p> Link to comment Share on other sites More sharing options...
MattB.Net Posted August 16, 2016 Share Posted August 16, 2016 <p>I'd send it back unless it was a "as-is" item. </p> Link to comment Share on other sites More sharing options...
ivan_j._eberle1 Posted November 26, 2016 Share Posted November 26, 2016 IIRC, with an insert installed, you've got to have film loaded in the P645N. You can't dry fire it without an flashing error code otherwise. Link to comment Share on other sites More sharing options...
mourgos Posted February 27, 2018 Author Share Posted February 27, 2018 Fixed it: Sorry for the delay of a year or so! I took the film rewind hole at the bottom and put a pen tip inside to force it to "rewind". After this I put film in, the ERR error went away and I was shooting fine. I've since fixed a friend's camera the same way. Link to comment Share on other sites More sharing options...
