Our sun rite tv screen shows smudges how to clean

No,u can't,this look like it cause by people doing something wrong to it outer LCD screen panel sell.Sorry u have to used ur tv as is.

can you feel if the surface is rough has it been cleaned with an abrasive cloth like a scouring cloth used for dishes as this will scratch the surface of the screen try getting a good polish spray on but dont spray to much on and use a soft cloth ideally a proper duster cloth see if they polish out if not the the screen surface has been scratched this can be polished out but you will need to get a pro to do this as doing it your self could ruin the telly permanenty as this is a delicate job to do hopefully you should polish these marks off but if not i would get somebody out to look at the telly to get the scratches polished out of the screen this should not cost to much but will save the frustration of watching a smuged screen the only thing you can do yourself is try polishing the screen properly in case she cleaned it and the cleaning product is still on screen if not you will need to get the screen profesionally polished goto a tv repair shop and these should tell you who to call hope this is some help to you but their isnt much you can do yourself

Unit needs cleaning and POSSIBLY cleaning the waste ink dump which is a blotter like sump that captures the waste ink during the jet cleaning cycle.

did you find a solution to this ? i have a TV doing the same thing.

probabally a dust spot on the mirror or the lcd mini panels inside the optical engine.
must be dissembeled to clean.
not for the faint of heart.

wipe battery clean with white napkin...re-insert, same thing happen....change battery.....if the phone is new you are under warranty

Yes, if you have used different lenses and a smudge still appears (in the same place) there may be something on your sensor. Have you cleaned or touched the sensor in the past? Typically sensors only get dust (shows up as small fuzzy dark spots) on the sensor, not smudges.

What kind of camera? Some camera's have removable fresnel lens held on by a spring loaded frame. Other camera's must be disassembled to replace the lens. There is no way to repair a damaged fresnel lens.
Pentax K1000 must be disassembled.

If you suddenly noticed it, this is most likely caused by a large piece of dust on the lens. It is hard to clean, you would need to take the whole TV apart in order to get to the lens (mounted on the optical block).

It could also be caused by a failure of the optical block, which had inherent issues. There is a pending class action law suit against Sony for problems with optical block that include smudges, hazes, and tints that appear after a certain number of hours.

Other causes could be a dirty portion of the mirror or a smudge on the inside part of the screen but these are rare because dust and contaminants do not usually accumulate on these parts of the TV.

Do a thorough manual cleaning of printerheads (where the cartridges sit). Many printers are notorious for clogged nozzles and the ink dries on he prinheads until it becomes a bandind issue or ladders appear, smudges too. Use a proper cleaning solution and cotton buds, until most colour is gone off cotton buds. Reinsert cartridges and try again.
