Texture appears on my photos, the settings are OK

You can spend $300 to $500 fixing this or just do the best thing most cost effective thing and replace the TV.

Please see the following comment:

It must the nozzle check is not perfect. Check nozzle and do head cleaning procedure. If there is just little nozzle clog ( 1 - 2 lines missing), you can get good result with best photo/photo rpm setting.

replace the ink cartridge

most likely a broken / faulty screen. may be the screen ribon cable but unlikely
cheapest option is to get a replacement from a broken camera (ebay or similar) and swap it out yourself.

there are a couple of "tricks" do getting this camera open drop me a line if you decide to proceed...

best of luck

sometimes I encounter vertical lines below..... when i tap the sides it clears for a time being  but after a few moment again appears

I have the same problem, this is my second cannon sent to me from them!

If the test patterns are not matching what your printer tells you is normal and your photos are banded horizontally, you may have clogged nozzles and printhead. Do a maintenace clean under your printers direction, and see if it now prints ok. Also, you may be low or out of one particular colour, but still have enough of the others and the printer will try to compensate by using available colours, hence colour banding and distortion. A manual clean with cotton buds and cleansing solution is recommended if the first clean does not help.

When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. An example of this can be seen in the pictures below. The photo on the left shows the fine plaids pattern on the shirt. The photo on the right is a distance shot of the same shirt. In this photo, you can see a ripple that is not visible in the photo on the left. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Look at the image above. This image shows red cross-stripes and black cross-stripes overlapped slightly misaligned. When you look at the entire image, you find a ripple that differs from either of the patterns. This is the same principle that causes the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly. Reference You may find another Moire effect displayed on the LCD of the camera. As this is caused by the aligned pixels on the LCD, this effect does not necessarily appear in pictures you have taken.
