Customer Question
I just bought a...

I just bought a Pentax MX on EBay and the Light Meter is behaving erratically. It jumps from fully over exposed (top red LED) to fully under exposed (bottom red LED) when adjusting the f-stop on the lens. I have tried two known working lenses from my Pentax ME, and both exhibit the same behavior. Sometimes the meter will settle down to a stable reading, but the slightest touch of the lens will cause it to jump to the maximum of minimum. Any ideas?

Technician's Assistant: Has there been any damage to your camera recently (e.g. from dropping or from dirt getting in the lens)?

The lenses work as expected on the ME. The MX was shipped from an E-Bay seller in Japan in December.

Technician's Assistant: What kind of battery does your camera use? Have you tried taking out the battery and replacing it?

I put brand new batteries in when I received it. It was shipped without batteries. I purchased the batteries that were listed in the manual that I found on line.

Technician's Assistant: Anything else you want the Camera Expert to know before I connect you?

That's all I know so far.

Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your camera question.
I would imagine from the sound of it, that your camera is defective - possibly it has a loose connection in the light metering circuitry area.

You may also try charging up the new batteries fully for 6 hours continuously (regardless of what the charger says before that time is over), but I don't think that will help with this problem. It may well require repairing by Pentax repair.

Pentax authorized repair on the national scale is probably best represented by
