When i print it is having a smudges lines in the letter black only .how 2 solve it?


Lines and smudges on the printouts are due to deteriorating cartridges and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner marks/ lines.
Also, make sure that the visible inside of the printer is clean and ther is no spilled toner inside.
Let me know if any further clarification/ assistance is required.


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Use warm water and you have to rub for a while but not too hard.
The longer the smudges have been there the harder to remove.
DON"T use any other kind of cleaner.
When I bought my new Sony flatscreen, I was sold a cleaner for the screen. After reading the manual it says not to use anything other than warm water, so I return the cleaner to surprized sales people!

Have two dark smudges on screen


Dear Chaplink,

You said "two dark smudges on monitor screen".

Asumming that these smudges are digital and not just something tata you can remove with cleaner, If your moniter is back-projecting then the issue is probably that the projector has been damaged.

If your monitor is a flat-screen then the gels inside of it are misplaced from somone touching and damaging your screen.

So basically, the only practical thing you can do is buy a new monitor.

Smudge looking marks onscreen


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.
