According to the manual, press the Vol (-) and (+) bottons on the top of the TV at the same time, and hold until the progress bar on the screen reaches the end.

My viewsonic n2751w tv will not stop channeling down... have to put weight on top to stop

mmm sounds like a sticky channel switch on your tv itself. Spray some special stuff called Contact cleaner spray available at any electrical outlet or hobbyshop - its a little bit expensive but works great to clean motherboards and most other electrical equipment. Spray while the tv is off and press buttons in between sprays

No matter what button I press, it says 'locked' on the TV screen. How do I unlock it?

Try holding down the Menu button on the remote for at least 5 seconds, the child lock is on, If this doesn't work go to samsung website and find your user manual and follow the procedure they suggest.

Screen changes colors only

Hold the Vol+ Vol- buttons down and turn on the power switch in the back of the unit.
The screen should turn blue and some square in the middle of it.
The noisy square is actually the bios being reset.
Once the unit turns itself off, you can turn it back as usual.
Note: Some of these units require a 3 button reset.
In that case hold Vol+ Vol- and Menu at the same time while you turn the power switch on in the back of the set.
I hope it was helpful.
