what could be wrong with my Pentax MX light meter?
i replaced the batteries but it still isn’t working. The rest of the camera is fine and in great condidtion but i need help with my light meter. any suggestions on what to do or what could be the problem?
how do i get to the photocells to check?
When you turn it on, the LED’s in the viewfinder should momentarily flash.
If no LED’s ever light up you have a battery connection problem. Make sure the batteries are inserted in the right direction and use a flashlight to make sure the contact inside the camera is not corroded by leaking batteries.
If the LED is only showing the bottom red one, you have a photo sensor problem. Use a bright light (not the sun) to see if the meter LED’s “move”. Dial through the f/stop settings and the shutter speed settings. Change the ASA/ISO setting. Sometimes, the contacts get a little dirty and moving them around fixes the problem.
Good luck
Update to your reply:
The light sensors are behind the focusing screen which is on the roof of the camera. I would STRONGLY recommend you not get into this area uless you are a) a highly skilled camera technician, b) not able to find a camera repair shop to check out your camera and are willing to lose your camera all together if you mess up. I would rather look for another used MX or use this one with a separate light meter than risk destryoing it by taking it apart and not knowing what I am doing. Check the other possibilities first.
Here’s the service manual if you are daring enough:
