The liquid between the 2 glass panels of the LCD has leaked from its pixel cells and the light path has been blocked. This happened because the LCD panel was either pressed too hard in that region or it was subjected to a temperature too high for it to support.
This is unfixable and it's going to get worse. Time for a new tv.

My sharp model lc-20b9u-sm has a dark circle on screen


Without seeing the dark cycle myself it is difficult to guess what. I only can think of something hit the screen (ball?) or perhaps someone bumped into the screen?
If the bump was minor, it could become lesser.
Perhaps you should ask a technician to look, or take a picture from the screen, one when switched on and one switched off, but close to where the dark circle is and take the pictures to a tech.

The Contrast and Brightness on tv appears to be dark.


If this is a CRT-based TV and it's been played most of the time, you may have a bad picture tube, especially if strong red colors bleed to the right. CRT's dim with use, unlike LCD or plasma. But it could also be trouble in the video circuits - none of this falls into the DIY category, unfortunately. High voltage involved, unless you're comfortable around it and want to try turning up the screen controls inside the TV. If you do, let me know - but "no response at all" from the external adjustments points to a more serious problem.

Two blue dots on the screen


its sounds like the guns has burnt your yube, when switching of does your tv show a bright circle in the middel, or while watching. Smack your tv on the side while on see if the picture goes away or make a bright circle in the middel, this is caused by a bad solder joint but you wont get rid of the bunt pixels sorry.
