I picked up an open box M7 from Best Buy in "excellent" condition. I later noticed horizontal lines similar to noise in an old TV or VHS in the viewfinder. After a quick search, it appears to be a common issue. Unfortunately, there are no other "excellent" condition open box cameras in my area so my options would be to upgrade to a sealed camera and pay the difference, downgrade to a "good" or "fair" open box camera that's available in the area, send it in for repair (I did get the Geek Squad plan), or simply return it.
For those that have sent in in their cameras for repair, was the issue fully resolved or did it still persist? For those that left it alone as it does not appear to affect the actual image, did the viewfinder progressively get worse? Are there any comparable cameras in the market (most interested in the zoom capability in the point and shoot form factor)?
Thanks!
