This is can be due to sensor damage or memory card damage.

  • Card damage (maybe repairable).
This is common with Flash memory that has been used extensively for a long time and this problem is likely not caused by any fault in the camera.
To check whether the damage is on the card or on the camera, copy a good picture from your computer and check it a few days later with a COMPUTER. If the lines appear on them too, you can say that the card is damaged.
If you want to try to use the card again, You can try formatting it (method differs from cam to cam, check instructions manual for specific instructions)
If this doesn't work, You will have to buy a new card. Make sure you buy a good brand like Lexar or SanDisk.
  • Sensor damage (unlikely to be repairable):
If you pointed the cam directly at something very bright like the sun (for taking pictures of an eclipse for instance), some parts of the sensor will get burnt. In this case you will get oddly colored dots all over the pics in the same places.
Parallel lines are consistent with other kinds of sensor damage like because of water.
I'm afraid that you might not be able to find someone to repair this cam; it's not a professional DSLR camera. which means repairs to it can cost more than buying a new camera will!

Hello sir, i bought this camera 2 year before. it

This camera has a fault. You cannot fix it by changing settings. It will probably cost more to repair than it is worth now. You can buy a new camera which will be much better than a camera from two years ago and cost less money.

Dark lines in background of picture its a sony cybershot dsc-s750

I think your camera chip is dying soon. Try taking a photo on a blank sheet of paper, black and white, see if there are lines. If there is, it shows that the camera chip is defective...

Problem with recording the picture

See if your camera has an ISO setting. If it does, make it a lower setting. 100 is best and move up from there (try to use no higher than 400). The lower the ISO, the more light you will need but your images will be less grainy.

Picture quality has become terrible

Ed, The shutter on your camera has become stuck open. This causes the lines across your pictures. If you take the camera outside or shoot in bright lighting conditions the pictures will come out over exposed. The fix for this problem requires complete disassembly of the camera to access the shutter assembly inside the lens. It is a fairly common issue due to the fact that the shutter is such a delicate component. Check with your manufacturer for warranty support or recalls. If they are unable to help you for free, there are repair providers which you can find online who will repair your camera for a reasonable rate. David Millier Advance Camera Repair
