Thank you all for your comments and suggestions. I don't want to sound totally negative... Because of my investment in lenses and other equipment, I have purchased a Pentax K-3. I do love it... I am just disappointed in Pentax because I would consider myself a decent customer and expected some help from them with the problem with the K-30. I will follow up with your advice. Thanks again for taking time to comment.

I purchased a Pentax K-30 just over 2 years ago. I noticed a problem with the contrast with many of my pictures 6 to 8 months ago. So, I changed lenses, updated firmware, changed settings, had the sensor cleaned, and often turned the camera off and then back on… The problem corrected itself until 3- 4 months ago. Then the image was either dramatically underexposed or completely dark. After investigating the issue online and in discussions with others who have experienced the same problem. I have noticed that several Pentax K-30 users have had this same problem. There are many blog posts and other forums where this is shared online. It is very frustrating to see that this problem seems to be widespread and there does not seem to be anything that the customer can do other than sending the camera to a certified Pentax repair facility (Precision Camera Repair) and paying a minimum of over $200.00 for diagnostics and a possible repair. I am confident that this shouldn’t happen to a camera that is barely 3 years old (or newer). I have also contacted Pentax. They are the ones that basically said that if the camera was over 2 years old and I did not have an extended warranty that they would recommend "Precision Camera". Any recommendations??
