IT SEEMS IT MY BE DAMP OR THE CAPACITORS IN THE POWER SUPPLY NEED TO BE REPLACED

my sansui LCD television flatview has a low contrast and color not good

I have a Sansui HDMI FLATVIEW tv - 34CM - however when I use my Playstation 3 to play games or view Blu Ray movies and use the HD cable - the TV gets extremely hot and the picture breaks up into what resembles a coloured bar code. I have to use a high powered AEG fan right on top of the TV which is wall-mounted. HELP as I am going crazy with this problem

It may mean that the code you entered is incorrect. Try these: 0135, 0310 and 0394.

is your TV have an audio out? then connect this to your amplifeir's audio in.
