Every picture I take is blurred

Still I think your CCD or CMOS sensor is damaged. The viewfinder, is just a set of lenses, where you can see through. It has no connection with the sensor. These type of camera's also use the sensor to focus. The sensor needs things with some contrast, where it should focus. But when the sensor is not working correct, the camera can't focus, or take a sharp picture. On your screen you just see what the sensor can record. Nothing more, nothing less.
I don't think it is worth repairing the camera, because this will cost more than you pay for a new camera, with better specs.
Sorry I can't help you with this.

It's probably something to do with a lag or jam on your shutterspeed. so when you hit the button, and move you get a little blur. If its not this you might need to have your lens cleaned inside and out due to the camera zooms and catches the blurs on the lens after zooming so far in. I would recommend taking it to your local camera shop for adjustments and cleaning.

That would depend on why the pictures are blurry.

If the pictures are blurred because of camera motion, you need to either use a faster shutter speed or place the camera on a tripod or other stable support.

If the pictures are blurred because the subject is moving, you need to use a faster shutter speed.

If the pictures are blurred because it's out of focus, you need to ensure that the camera is focusing on what you consider to be the subject, not what the camera chooses.

On TV shows, they can take a blurry picture and enhance it to crystal clarity. In real life, however, those kinds of miracles aren't possible. In a photo editing program like Photoshop Elements, you can bring up the sharpness a little but you eventually reach a point where the picture no longer looks like a normal picture. The slogan is "garbage in...garbage out"...meaning you can only do so much to what you have to work with.

yes can be repaired,it is the problem of the focusing unit of the lens unit.

Try reseting all menus to default, then try again to test.
Make sure the lens is clean.
Do the menus appear clear?
Has the camera ever been dropped or had any other damage? This could get the lens out of focus, and would need repair.
Does blurring happen when zooming or when taking a picture of any kind?

Did you try turning the ring in front of the camera?

Viewfinder has focus lever at bottom, please adjust viewfinder internal focus as per your eye sight looking on-screen display. Every thing will be fine after that.

Have you tried to change the settings like to scenery or adjusted for lighting that could have an effect. The only time it's blurry for me is when I don't adjust for the picture I am taking. The camera itself focuses so maybe there hasn't been enough time for it to focus. Try those things and if it doesn't work I would take it in to a camera shop maybe it has internal problems.

one of the possible cause of the said problem can be a defective or broken flex ribbion cable carrying signal to the focus motor. the replacement of the flex will solve the problem. othe may be friction in the focus assembly. cleaning of the same will do the job. but in both the cases you will need the help of repair shop.
