Try a hard reboot of the camera and a firmware update or reinstall...

If those or different memory cards don't cure the problem, it's very likely a bad sensor or something downstream from the sensor going bad.... In which case you probably should try to get your money back. That's not a case of "sometimes the colors are a little off". That's a completely whacked out looking image.

*Sigh* It's gotten worse, and it's happening almost every time I turn it on. Totally unusable images unless it's the size below, which isn't anywhere near large enough for some things I need it for.

Could it be a dust-in-the-sensor thing? Any suggestions for trying to clean it? I just asked the person I bought it from if she'd take it back, but I sincerely doubt she's going to.

Dust on the sensor shows up as splotches, not lines. If it's getting worse, most likely it is a fault with the sensor or the supporting electronics.


Not sure why, but call me JJ.

This.

Looks like you bought a dead camera.

Well, thank you for all the help. I tried a hard reset (I think — taking out the battery and letting it sit switched to On?), and I'll try the firmware, but it looks like I got screwed. I've been buying laptops, cameras, lenses and phones from eBay and Craigslist for years and never had a problem. Guess it was bound to happen some time :/

Sorry to hear about your bum purchase. You might as well try to get your money back or at the least ask the seller to refund a portion to help you with the repair. She might say yes.

You need to take out both batteries, the main, and the backup. The backup is the little one right by the main.

Found ref here but this thread dates back to 2008 http://www.fredmiranda​.com/forum/topic/62538​1 (external link) so could it be that some early models had an issue and for the record mine was bought in 2007 and as fas as I can tell does not have the issue :)

Sorry if I missed it but you say high Q JPG but the screenshots you post say CR2 which if the RAW file ~ I think you have serious porblem with the sensor or possibly the DIGIC processor but either will costly to repair?? Can you get a refund???


That was a great meal ~ you must have a good set of pans :p

gj711, Thanks! I had no idea that backup battery even existed. I tried that, and it could be a coincidence but now the pictures look good for the first time today! I'll keep checking.

Box Brownie, yesterday afternoon I was trying it with JPEGs, but last night I tried it with RAW to see if it would help.

I emailed and called the woman I bought it from, but no answer yet. I don't have high hopes for a response.

Well, I've tried it every 20 minutes or so for the last half hour, and it seems the reset JUST MIGHT have done the trick. Thank you so much, gj711!!! Now I get to spend the rest of the night playing with my new 50mm 1.4 in dark corners...

Congrats, but I would still look at returning the camera. That's a major issue (even if it's just in the electronics)...

The seller is ignoring me, unfortunately. Maybe I'll have my email/phone call returned tomorrow, but I doubt it. :rolleyes:
