Without a remote control, switch off the blue-screen will be almost impossible. You have to enter its picture menu to switch off the screen status.

Tv's sound is not coming through but the tv's sound test is working


Go into the sound menu and make sure the speakers are set to the TV , or the audio system you are using.
If they are turned on , then reset the systems sound settings to clear any previous settings .
The preset volume may be set too low and you are using your surround systems volume controle?
try turning up the volume on the set manualy... ?

Dark spot on the right hand side of the screen


check make sure you didnt put your tv next to some thing that has a magnet in it such as speakers either from a radio or home surround sound system this will cause the problem and if its been sitting beside a magnet for awhile your probably not going to be able to fix it
